Furnace Odors Homeowners Should Not Ignore

Share on Facebook

Every homeowner should be alarmed by odors emanating from the furnace. If you smell any sort of odor coming from your furnace or vents, do not shrug it off as a side effect of the system's natural operation. Such odors are a sign there might be a serious underlying problem. Be proactive by reaching out to our HVAC experts for assistance. Let's take a look at furnace odors and what they typically indicate.


A Musty Odor


A damp or musty odor stemming from your furnace is an indication that a new condenser pump is required. The furnace condenser pump accumulates water from the furnace system, and should be cleaned at least once per year. Dust and water gradually builds up within the pump, spurring the formation of bacteria and mold. If you still smell the odor after cleaning the condenser pump, the odor is likely emanating from something else in your home.


A Burning Odor


This odor often occurs when the you turn up the thermostat to a higher temperature than normal. If you haven't operated your furnace in months, dust will have gathered within the combustion chamber. This dust will burn and create the burning odor. There might even be some smoke generated when the furnace is turned on. The problem is worsened if the furnace filter is dirty and rife with dust. It is also possible for brand new furnaces to generate a burning odor as the oil that prevents internal components from rusting is burned away. If the odor extends beyond the first day of use, it is a sign something else within the furnace is burning and professional attention is required.


An Electrical Odor


The vast majority of electrical odors are the result of broken furnace parts. This odor is similar to an iron that has overheated or blazing hot metal. If your furnace's air filter is dirty, it heightens the odds of electrical components becoming overheated. If furnace components are heated to the point that they malfunction, they must be replaced.


Generally Foul Odors


Generally foul odors are sometimes attributable to dirty air ducts. Have your air vents cleaned and the odor might dissipate. It must also be noted some foul odors are the result of small animals like birds and rodents that find their way into HVAC ventilation systems. The scent of the animal carcass will spread throughout your home until the remains are removed.


Waste Odor


If you smell pet urine when your furnace is in operation, take a look at the floor ventilation registers. If your pet has relieved himself by the vent, the odor will spread when the furnace operates.


The Odor of Gas or Rotten Eggs


If your home reeks of fuel/gas or rotten eggs, there is a chance it is the result of your natural gas or oil furnace burning fuel. However, if the odor stems from any part of your home away from the furnace, it is an indication there is a significant gas leak that has the potential to cause an explosion. Reach out to your fire department right away if the odor is not emanating from the furnace.

How to Prepare Your Furnace for Winter

Share on Facebook

Winter is quickly approaching. This is the ideal time to have your furnace inspected, tuned up, and repaired. The last thing you need is for your heating system to give out in the dead of winter. There are a few things you can do on your own to get your furnace ready for those low temperatures.


Clean up Around the Furnace


Most people keep other items in the room or space where their furnace is located. In some instances, the furnace is laden with stored items as it has not been in operation for months and has ample surface area. Relocate all items that are placed on or by the furnace. Give the surrounding space a thorough cleaning. Be sure to vacuum the exterior of the furnace to eliminate cobwebs and dirt. Finally, check to ensure the furnace is completely visible. The pilot light should be seen with ease.


Replace/Clean the Filter


Your furnace filter collects all the dirt, dust, and grime when air intake occurs. The filter should be cleaned prior to the start of winter. Ideally, the furnace filter should be cleaned once per month. If you find that the filter is clogged and in poor condition, replace it. A clogged and/or worn out filter will result in a high energy bill because it will require your furnace to work that much harder and longer to warm your living space.


Mind the Burners and Heating Vents


If the furnace burners are obstructed, they will prevent the proper flow of gas and lead to the release of carbon monoxide when the system is turned on. Make sure the burners are clean and do not have obstructions, like debris or dust, blocking them. Check the heating vents as well to ensure they are not obstructed. If heating vents are blocked, warm air won't spread throughout your home. It is even possible for blocked heating vents to overheat to the point that a fire forms.


Bearing Lubrication


If your furnace is old, it has plenty of moving parts that function with the assistance of bearings. These bearings must be oiled. If they lack lubrication, they will eventually wear out and the furnace will not function at optimal efficiency. A lack of bearing lubrication can also lead to costly repairs. Pinpoint the oil caps above the bearing shaft and apply oil.


Check the Blower Doors


If the furnace's blower doors are not tightly shut, harmful heating byproducts like carbon monoxide might mix with the warm air that circulates throughout your living space. Make sure the blower doors are firmly closed prior to operating your furnace in the winter.


Mind the Fan Belt


The fan belt is a vitally important component of the furnace. Make sure it has tension and doesn't have obvious signs of wear and tear. If the belt is too loose, the furnace will require an excessive amount of time to heat your home. Loose belts also cause the furnace to use more power/gas than necessary. Go ahead and unscrew the cover of the air handler, find the large rubber fan belt and check its integrity. If the belt is frayed, cracked, or compromised in any other manner, it must be replaced. If you do not feel comfortable conducting such an inspection, reach out to our team so we can do it for you.


Be Proactive


Lastly, be proactive by reaching out to our team for a furnace tune-up and inspection now and you will dramatically reduce the odds of malfunction throughout the winter.

The Importance of Air Duct Cleaning

Do not make the mistake of turning on your heating or cooling system and assuming the air emitted through your home's ducts will be perfectly clean. Just like any other space, air ducts gradually accumulate dirt, dust, allergens, and other particles. You and your loved ones should not be exposed to these contaminants each time you turn on the furnace or air conditioning. It is even possible for such particles to build up to the point that they impede the flow of air.

Air Duct Cleaning Frequency

Air ducts should be cleaned at least once every two years. Frequent cleaning will guarantee that your family breathes in the cleanest possible air. If you wait longer than a couple years to have your air ducts cleaned, you and your loved ones run the risk of breathing in everything from allergens to mold, dust, dirt, and all sorts of other unsavory particles.

The Strangest Things Find Their Way Into Air Ducts

Some air ducts serve as makeshift living spaces for insects, small animals, and other vermin. Pollutants can accumulate in this space and be recycled through your heating and cooling systems over and over again, and manifest in the form of black debris along the outside of the vents and/or furnace filter. Such debris is an indication that your system is soiled. Air ducts can also contain mold, mildew, animal droppings, and all sorts of other nasty gunk that should not be redirected to your living space each time the furnace or air conditioning turns on.

Air Duct Cleaning Combats Sickness and Respiratory Problems

If anyone in your family has asthma or any other respiratory problem, it is even more imperative that you eliminate dust mites from your living space. Those who suffer from allergies should not be exposed to dander or pollen. Each of these particles will inevitably accumulate in your home's air ducts unless they are cleaned at the proper frequency. Do not assume you will be able to spot such particles. They are microscopic and therefore are too small to see with the naked eye.   Have your air ducts cleaned frequently and breathe in the fresh and clean air you deserve, and you will find you feel much better.

Increased Efficiency Means Big Savings

Air ducts that are not cleaned for years will gradually build up particles. These particles will eventually block the flow of air. Some will be transported right on back to your heating and cooling systems. The end result will be a reduction in air flow through the ducts, inefficient HVAC operation, and ultimately, higher utility bills. Consider the following statistic: the United States Department of Energy reports upwards of 40 percent of energy used to cool or heat a living space is wasted. Aside from wasting energy, dirty air ducts will also force your system to work harder to reach your selected temperature A system that is forced to work harder than it should will break down that much quicker.

Have your air ducts cleaned by one of our professionals and you will rest easy knowing you are breathing in the cleanest possible air.

Signs for Air Conditioner Replacement

When something goes wrong with an air conditioner, it is often difficult to determine if a repair or a replacement is necessary. Oftentimes, even the most experienced air conditioning professional isn't completely sure as to what the best decision is. The bottom line is no one can predict how an air conditioner will perform following a repair. It might function without flaw for years to come or require an additional repair in the coming year. Let's take a look at some general guidance regarding air conditioner replacement and repair to help homeowners make the best decision.


An air conditioner that reaches 10 to 15 years old and requires multiple repairs should be replaced. There is no sense in spending money on multiple repair projects once your air conditioner has reached a decade in age. In general, if an air conditioner repair bill is one-third or more of the cost of a new air conditioning system, it makes sense to invest in a completely new system. This is especially true for air conditioning systems that are near or beyond 10 years in age. Invest in a new air conditioner and you will enjoy the many benefits provided by today's energy-efficient models. These new units reduce utility bills and generate incredibly clean air. A new system won't require a steady stream of repairs like an air conditioner that is nearing the end of its useful life.


Take a look at your monthly energy bill. Compare it to the prior month's bill. If there is an upward trend even though you have not decreased your thermostat temperature setting, your system might need to be replaced. Older air conditioning systems' inner mechanisms eventually become worn and require an abundance of energy to generate cool air. In some instances, a repair can be performed. Yet there is no guarantee the repair will stand the test of time. It is possible numerous repairs will be required, making it more economically prudent to invest in a new system.


Signs for Air Conditioner Repair


A home that is not cooled in an even manner is cause for concern. The temperature in bedrooms should not be drastically different than the temperature in the living room or other spaces. Air conditioners that are in proper working order spread out cool air in an even manner across the home's entirety. In many instances, uneven cooling is the result of clogged air ducts. Have the ducts cleaned and the cooling might even out. It is also possible that the air conditioner itself is malfunctioning.


If your air conditioner turns on and off without much time between the cycles, it requires a repair. When functioning properly, air conditioners cool a living or working space to a temperature below the level set by the user. It turns back on once the air returns to the selected temperature.


If you notice system warning lights on the interface, don't panic. This is a sign your air conditioner requires some sort of repair or maintenance. Reach out to our air conditioner aficionados for an in-depth analysis and repair.

  • Air Scrubbers/Cleaners
  • Electronic Recovery Ventilator
  • Vent/Duct Cleaning
  • Humidifiers/Dehumidifiers
  • Changing Air Cleaners/Air Filters

Contrary to what people believe, the air quality indoors is usually worse than the air quality outside.  The air we breathe inside is often far worse than the air quality outside and the reason for that is because the contributing factor to poor indoor air quality is that newer homes are generally more efficient and have airtight seals. In fact, today’s energy efficient homes are constructed with materials that seal the home tightly and reduce air flow.  Energy efficient homes not only help with energy consumption but they also reduce air flow allowing toxic pollutants to build up and contaminate the air you breath. 

Indoor Air Quality Solutions

What’s so important about the quality of the air you breathe?  Be certain you have the best indoor air quality possible.  It can be the most important decision you make!  Having good air quality is an important factor in supporting the well being and health of your entire family.  There are many contributing factors that make the air quality worse in your home and cause problems to your health.  Homes have indoor contaminants that include pollen, bacteria, mold, pet dander, tobacco, chemicals used for cleaning, dust mites, and fumes left over from cooking.  Poor air quality can diminish a person’s quality of life and contributes to a number of health issues, including; poor immune system, allergies, sinus infections, upper respiratory infections, and other negative ailments.  Some people can develop severe breathing problems if the air within a home is not clean and fresh.

Signs It is Time to Have Your HVAC System Inspected by a Professional


Most heating and cooling systems function without flaw across all four seasons. However, there are some instances when the attention and expertise of professional HVAC technicians is necessary. If you notice any of the red flags outlined below, reach out to our heating and cooling experts for an in-depth inspection. We will diagnose the problem, develop a plan of action and provide you with a free quote.


Odor Stemming From the HVAC System


If you notice any sort of odd odor coming from your heating or cooling unit, it is cause for concern. It is possible a part is overheating, that a small rodent or insects are trapped in the machine/ducts or that something else has gone wrong. Let our experienced HVAC professionals inspect your system to determine exactly what is going on.


System Warning Lights


If any of the system's warning lights are illuminated on the thermostat interface, do not shrug it off and assume the system will function as designed. The illumination of such a light is a sign that something might be seriously wrong with your heating or cooling system. Do not wait longer than a couple days from the time in which the warning light illuminates to call our HVAC professionals.


Odd Noises


If your heating or cooling system is making unexpected noises, there is likely a problem that requires the attention of a professional HVAC technician. Though every heating and cooling system will make a little bit of noise during operation, particularly loud noises are a warning sign. Any sort of clanging, grinding or banging noises from your heating or cooling system must be addressed so the problem doesn't worsen and spiral into an even costlier project.


Energy Bills are Rising Without a Temperature Change


If you haven't adjusted the temperature of your living or working space but your energy bills continue to go up, there might be something wrong with your system. You should not have to pay through the nose to heat or cool your home or office when you aren't setting the temperature at a particularly low or high level. The solution might be a surprisingly simple repair of your thermostat or heating/cooling system.


Issues With the System Turning on and Off


If your heating or cooling system won't turn on or off or continues to cycle on and off in a repeated fashion, it requires the attention of one of our HVAC aficionados. You have plenty to lose from a furnace or air conditioner that turns on and off over and over again with little time in between cycles. Such activity will increase your utility bill and unnecessarily tax your heating or cooling system. This overworking of the system will cause significant wear and tear and possibly force an early replacement. Contact our HVAC professionals for an accurate diagnosis of the problem. We'll get your heating or cooling system back in shape so it maintains your selected temperature without constantly cycling on and off.

The Importance of Regular HVAC Maintenance

Heating and cooling systems are just like any other piece of machinery in that they require occasional maintenance in order to function as designed. Periodic HVAC maintenance will ensure your heating and cooling systems produce high-quality air, remain functional for years if not decades and keep your energy bills as low as possible.

Enhanced Indoor Air Quality

The typical homeowner assumes his heating and cooling systems will generate warm and cool air that is perfectly clean. Though this is true most of the time, neglected HVAC systems can reach the point where they emit low-quality air. You and your loved ones deserve only the best air. Take a moment to think about all the time you spend indoors. You sleep, eat and relax in your home for upwards of 16 hours per day or more. Regular HVAC maintenance will ensure your system's air filter isn't clogged or faulty in any other way. This filter must be periodically cleaned or replaced to ensure dust, allergens, dirt and other nasty particles do not enter the equipment and taint your air supply.

HVAC Maintenance Prevents Major Problems From Developing

Let one of our knowledgeable and experienced HVAC gurus inspect and maintain your heating and cooling systems at least once per year. This opportunity will give us the chance to identify potential trouble spots. Nipping these problems in the bud before they spiral out of control is essential to maintaining your comfort as well as your budget. Repairing a minor problem (or a potential problem) now will likely prove much cheaper and easier than rectifying a major breakdown that occurs weeks, months or years later.

Peace of Mind

One of the most underrated benefits of regular HVAC maintenance is peace of mind. You will enjoy a powerful sense of peace and relief knowing a savvy heating and cooling expert has analyzed your HVAC system before and after those blazing hot summers and frigid winters. Our technician will check everything from the system's connections to its electrical components, filter, safety controls, cleanliness, airflow, belts, blowers and overall operation. You will rest easy following this maintenance, knowing your heating and cooling systems will keep you perfectly comfortable no matter how hot or cold it gets.

HVAC Maintenance Saves You Money

There is no better reason to have your heating and cooling systems maintained than to save money. A HVAC system that runs in an efficient manner is clean, properly insulated and capable of warming or cooling a building to a specific temperature without turning on and off with little time in between cycles. This maintenance will prevent your system from working harder or longer than it has to. The ultimate result is a reduction in your utility bill.

Prolong the System's Lifespan

Regular HVAC maintenance will also extend the lifespan of your heating and cooling systems. A well-maintained, well-functioning HVAC system will keep your living or working space at the desired temperature for upward of a decade or longer. Think back to the massive investment you made in this system. All it takes is periodic maintenance to ensure you get the most bang for your buck.

How to Prepare Your Air Conditioner for Winter's Wrath

Share on Facebook
Winter is right around the corner and that means it will soon be time to turn off the air conditioning and start up the furnace. However, simply turning off your air conditioner and assuming it will function without flaw once next summer arrives is a mistake. Be proactive by preparing your air conditioner for the harsh winter. Minor preparations made in the coming weeks can make a major difference when you turn the air conditioner back on eight months later. Follow these steps to keep your air conditioner in tip-top shape across winter's duration.

Turn the Air Conditioner's Power Off

Start out by turning off the exterior power to the unit. Air conditioners are designed with an exterior circuit that controls the power that is sent to the unit. Open the box on the side of the house by the unit and pinpoint the red circuit handle. Flip it upside down then reinsert it in the slot. Close the box's lid. Turning the power off will prevent damage to the air conditioning unit and also prevent you and others from being electrocuted when working with the unit. Furthermore, turning off the power will prevent the air conditioner from accidentally being placed in the “on” position in the midst of winter. The last thing you want is for your air conditioner to be errantly turned on in the winter months when its water can freeze and damage the unit's condensing unit.

Cover the Air Conditioner's Pipes

The pipes that extend from the air conditioner to your house contain water. They should be wrapped with foam insulation strips and secured with duct tape so they are not exposed to winter's freezing temperatures. You can also use foam blocks and duct tape to protect these pipes.

Clean Around the Air Conditioner Unit

Take a close look at the area around the air conditioner. If you spot any sort of debris like leaves, lawn clippings, branches or other items, sweep, rake or pick them up. Clear out at least a two foot radius around the air conditioner. Trim plants that are growing over or near the unit. You can also use a hose to wash off bugs and grime from the condensing coils and fan blades. Such a thorough cleaning will reduce the chances of clogging and combat rust/damage. It will also make the area less inviting to animals looking for a new home.

Protect the Unit

It is important to safeguard your air conditioner so leaves, ice, snow and other items do not seep in. Grab a square of plywood and place it atop the system. Place a large rock or a brick on top of the plywood to keep it firmly in place.

Take protection a step further by covering the unit. Wrap a thick plastic or vinyl tarp around the unit and tie it together with rope or bungee cords. Leave just enough slack so residual debris, moisture and condensation aren't trapped inside.

Best Ways To Improve Your Home’s Air Quality This Summer
When Summer comes around maintaining your AC is probably the last thing on your mind. However, AC maintenance should be at the top of your list for home maintenance priorities as it helps to improve the quality of your air. Cooling systems that are kept in proper condition can improve the air circulation which makes the air that you breathe better for you.

Since the inside of your home is where you likely spend the most of your time, it is important to ensure that the air quality you breathe is clean. The reason for this is because the impact the air can have on your body can have both negative and positive effects. Experts at the Temperature Pro of Maryland list several three ways you can improve your air quality and how this can improve your health and increase the enjoyment you receive from your home environment.

Would you rather skip our tips to improving air quality and hire us to clean your AC instead? Contact The Temperature Pro of Maryland today to get started!

Tip #1: Replace Your HVAC System Filters
Depending on the air conditioning system you have, your home’s HVAC system filters should be changed periodically on a routine, monthly basis. The golden rule for the amount of time to have in between replacing your AC filters is once per month, however some AC systems can get away with only needing the filters to be changed every three months. HVAC systems that only need filters replaced a few times a week. Doing this will ensure that the air being blown throughout your house doesn’t contain high amounts of dust, dirt, and other toxic substances that can affect the integrity of your health and the air your breathe.

Tip #2: Buy A New Air Conditioning Unit
If your systems are particularly old, or in bad condition for one reason or another, it might be time to invest in a new air conditioning unit altogether. Not only will a new system naturally guarantee clean air quality circulating throughout your home, but it can save you money too.

Tip #3: Open All Your Windows
If you’ve already taken the appropriate maintenance measures for cleaning your HVAC system and air conditioning units, the next best thing you can do to improve the air quality in your home is to simply open up the windows from time to time. This allows fresh air to come through and prevents dirty air from becoming stagnant and being re-circulated throughout your home.

Tip #4: How Can HVAC Maintenance Improve Your Indoor Air Quality?

Many homeowners don’t realize that they can improve indoor air by simply giving their HVAC system some routine TLC. Most residential cooling and heating systems blow air through ductwork, which is referred to as forced air. Each HVAC system also has an air filter with the primary purpose of keeping dust out of the equipment.

Tip #5: Upgrading Air Filters to Improve Indoor Air Quality
For people who suffer from airborne allergies, an easy way to improve the air quality and filter out contaminants in the HVAC system is to install a better filter quality. All filters have MERV (minimum efficiency reporting value) ratings, which are indicators of the size of particles they can trap. The scale runs from 1 to 16 for residential purposes. The higher the MERV rating is, the cleaner the air in your home will be. For example, fiberglass filters have ratings from 1 to 4 and cannot trap the most irritating particles, like dust mite waste, mold spores, pet dander, and pollen. Pleated filters have 5-8 MERV ratings and will trap the more offensive particles. Some filters have ratings as high as 13, but it is best to check with your HVAC contractor or your system’s owner’s manual before selecting filters with high ratings as they can slow down the airflow as much as a dirty filter would.

Tip #6: Clean Out Air Ducts
Having good air filters will assist in keeping air ducts cleaner, which will help you and your family breathe better. Over time, dust collects in the ductwork of the HVAC system which in return calls for the need of professional duct cleaning services. Signs of problems with the air ducts include smelling odors or seeing dust deposits near the registers more often. You can remove the register cover to see how much dust and debris has collected inside the ducts.

The best way to prevent a dust buildup is to check the air filter monthly during cooling season and replace it when it’s dirty. Higher density filters trap more particulate matter and may need to be changed more frequently since more dust particles will be collected inside the filters.

How Your Air Conditioning System Works

Share on Facebook
Your Air Conditioning system is composed of 3 primary parts: 1) Compressor; 2) Condenser; 3) Evaporator. The compressor and condenser are normally on the outside of the building and the evaporator is normally located on the inside the building and can be a part of your furnace.

Air conditioners use a chemical, or refrigerant, that easily converts from a gas to a liquid and back to a gas again. This refrigerant is used to transfer heat from the air inside of a home to the outside air.

The refrigerant is a cool, low-pressure gas when it reaches the compressor. The compressor squeezes the refrigerant causing the fluid to increase its energy and changes from a liquid to a gas and absorbs heat from inside the building in the process. As a high pressure gas, the refrigerant leaves the compressor and flows to the condenser. The condenser serves as a ‘radiator’ and helps the heat to be released from the system into the air.

As the refrigerant leaves the condenser, its temperature cools allowing the refrigerant to convert back from a gas to a liquid. The liquid travels into the evaporator through a very tiny, narrow hole. On the other side of the evaporator, the liquid's pressure drops causing it to evaporate back to a gas state, and as it evaporates, it extracts heat from the air around it. As the refrigerant exits the evaporator, it is now a cool, low pressure gas. It then returns to the compressor to begin its trip all over again.

Connected to the evaporator is a fan that circulates the air inside the house to blow across the evaporator fins. Hot air is lighter than cold air, so the hot air in the room rises to the top of a room. There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the house through other ducts usually at the floor level. This cycle continues over and over again until the unit turns off usually by a thermostat when your indoor air reaches a certain present temperature.
