What To Check Before Alerting Your HVAC Contractor

HVAC challenges are not always as complicated as thought. Carrying out some basic troubleshooting can help save you your hard-earned cash and time booking irrelevant HVAC services. You don’t have to always be in haste to call your HVAC contractor; take your time to check if it is something you can handle yourself before placing a call. Here are some vital things to check out before scheduling an HVAC service appointment.

Zero Heating and Cooling

Have you detected that your heating and cooling system is not blowing out cool or warm air? Then, you don’t have to call your technician right away. First, check if the system is turned on. If you switched it on and off and the issue remains, check the circuit breaker. There is a dedicated circuit breaker for every HVAC unit, and this part may have been tampered with. The next thing to do is make a reset to restore the power on the HVAC unit. Also, do a reset on the thermostat. For individuals using mini-split ac units, if only the indoor unit is functioning, try turning off the thermostat for at least 1-3 hours. Some models of HVAC are made to self-reset when turned off for more than an hour. After all, if your system is still not blowing well, call for an expert HVAC contractor to inspect it.

Increased Utility Bills

Besides maintaining comfortable indoor air quality, heating and cooling systems also preserve indoor temperatures. So if there is a case of heat leaks – like leaky windows or inefficient insulation – the HVAC is forced to increase its output so the difference can be balanced. This boost would eventually lead to a rise in energy or utility bills. When the HVAC thermostat is not properly set, it increases the HVAC system’s energy needs. So all you have to do is make sure your thermostat is set in between (not too hot and not too cold). This would balance the error.


Lack Of Airflow

If you detect that your HVAC unit is on, but the airflow is not coming from the vents, something must be blocking the air. Inspect the filters and be sure they are not dirty. Note that the air filter needs to be replaced quarterly. Or it can be replaced after a long period of heavy usage. Air ducts need resealing and cleaning from time to time, like about 3 to 5 years. Proper maintenance of the air ducts keep it safe from leaks and maintain efficient indoor air quality. 

Constant Running Of HVAC System

A standard HVAC system is supposed to go off automatically when it detects that the room has reached a comfortable temperature. If it seems to be constantly running, then it’s time to check your thermostat setup. It could be that the thermostat has been set at a temperature that is too high for the heating season or too low for the cooling season.


As a homeowner, there are so many other things you need cash to take care of. Some issues with your HVAC system could be rectified by yourself; however, if you noticed that the issue is serious and beyond your idea and experience, reach out to an expert HVAC contractor immediately.
