Heating Cooling and the Filter Change

One question that frequently comes up is when you should change the filters in your heating and cooling system. An air filter may seem insignificant, but not keeping up with your heating and cooling systems maintenance schedule can decrease the unit’s efficiency and could cause expensive internal problems.

Air Filter

A clean air filter will offer little to no restriction on air flow. A dirty or clogged air filter will cause a significant reduction of air flow. This could cause the indoor coil of your HVAC system to freeze almost stopping the air flow completely.

TIP!The ducts that move the air to and from the air furnace, central air conditioner, or heat pump typically are energy wasters. Remember to seal and insulate the ducts.

Filters can last for long time, so we have to also remember the surrounding environment and take that into consideration. In a relatively clean environment you expect to get a much longer lifespan out of your HVAC filters. In an environment where there is a lot of dirt, more recent construction and pollen you will have to change your filters much more frequently.

HVAC and Air Filters

Your heating and cooling system is actually filtering the return-air, not the supply-air. This is often a misunderstood concept. With that being said whatever dirt, dust or pollen that inhabits your space will be caught up in the air-filter. Once the air filter has reached its capacity it starts to lose some of its efficiency as does your HVAC system.

To better understand this, think of yourself with a cold and stuffy nose, it is harder to breathe. This is exactly how dust and dirt affects your HVAC system. When the return-air has been restricted it will not allow the HVAC system to heat or cool efficiently.

TIP!A properly sized, installed and functioning heating and air system will circulate the air in your home every hour. In the process, it pulls that air through a filter.

There is not a specific timetable for changing the air filters in your commercial or residential HVAC system. You simply need to get a good feel for your environment and then check on the filters periodically to keep your HVAC system running efficiently. If you do not have the time to maintain your HVAC equipment it is wise to call in the professionals like the ones at Heating Cooling Chapel Hill. They will help you schedule routine maintenance for your HVAC system.
