As is the case with any complex mechanical system, your home’s HVAC system consists of a number of components which all have to be functioning well in order for this system as a whole to perform smoothly and efficiently.

When all these components are well-maintained and functioning properly, so will your HVAC unit be functioning properly. This is important to you because of the comfort and indoor air quality the system provides, as well as for its ability to keep energy bills lower.

When something goes wrong with your HVAC system in Mesa, Tempe, Chandler, Scottsdale, or Gilbert, your first call should be to Simply the Best Heating & Cooling, so service can be restored promptly and effectively.

The following reasons for failure are among the most common with HVAC units in general, so when your system isn’t working right, chances are it will be for one of these reasons. Check these first before making a call to the professionals.

5 COMMON REASONS FOR HVAC FAILURE

Dirty Filters

If this is the only thing wrong with your HVAC unit, it’s an inexpensive fix to make. Filters should really be changed monthly during peak seasons of warmth or cold, so that all trapped pollutants can be discarded, and not recirculated throughout the home. When filters are not regularly changed, they make an HVAC unit work twice as hard, because the pollutants create a barrier which hinders airflow.

While not the peak seasons of your HVAC system running, changing your filter every 3 months is a good rule of thumb. If you have a washable filter, you can wash it every 3 months.Not changing your HVAC filter is one of the most common reasons we see heating and cooling systems fail. This is the easiest part of preventative maintenance that you can do.

Improperly Balanced Dampers

Most ductwork systems in homes terminate at individual rooms, and have dampers in the main supply line which act to control airflow throughout the ducts. When dampers are not properly balanced, some rooms may be heated or cooled much faster than others, but when dampers are properly balanced, all rooms are equally heated and cooled.

If you aren’t sure if your dampers are properly balanced for your Tempe, AZ home, give us a call and we’ll come out before your HVAC fails, inspect your system and let you know if you are getting the proper airflow to each room.

Broken Thermostat

Broken thermostats are the root cause of far more HVAC system failures than you might think, and fortunately, this is one of the simplest and least expensive repairs you can make on your heating or cooling system. The only bad thing about the thermostat being the culprit for so many problems, is that it’s usually not obvious to the occupants, and requires the knowledge and experience of a professional to uncover.

If you do have a broken thermostat, this would be a good time to upgrade to a newer smart thermostat. Smart thermostats can lead to lower energy bills as well as greatly increased convenience.

Leaking Refrigerant

This is a common problem with air-conditioning units, and it can cause either poor performance, or no performance at all if the problem is bad enough. Condenser units in your air conditioner require a refrigerant in order to cool incoming air for your home, and when there isn’t enough refrigerant in the system, there’s no way for the air conditioner to function correctly.

With low refrigerant levels, the condenser works harder than it’s meant to, and that creates additional problems, which can lead to a complete breakdown.

Breaker Was Tripped

When your HVAC unit won’t function at all, there’s a possibility that the circuit breaker was tripped, and the breaker provides the flow of electricity which powers the unit. You may be able to restore power by resetting the breaker, but there’s also a chance that some other problem caused the breaker to trip in the first place.

If resetting the breaker solves the problem, then it may have just been a fluke, but if the breaker trips again, the safest thing to do is contact a professional electrician.
