Four Most Common HVAC Issues and How To Deal With Them

No homeowner wants to think about the potential of their HVAC system not working one day--especially on a hot and humid summer day. However, you’ll be more prepared to deal with the situation if you know about the most common HVAC problems you’re likely to face.

#1. A Problem with the Refrigerant

Refrigerant is delivered to the evaporator coils in your unit so that those coils can remove heat and humidity from your home. If there is a leak somewhere in that pipeline, the evaporator coils aren’t getting the proper refrigerant flow they need to expel the hot air and humidity from your home. The most obvious sign of a refrigerant leak is the noticeable loss of cooling and possibly the presence of ice on the evaporator coils and refrigerant tubing; as a result, that leak could also mean that you don’t have enough refrigerant to cool properly. If your supply of coolant is too low, your HVAC system has to work harder, run much longer, even though it isn’t delivering the desired results.

Either way, when you have a problem that’s related to your HVAC system refrigerant, call a professional Coolray HVAC technician to assess the issue.

#2. Your Thermostat

If you’re not getting accurate temperature readings, the first thing you should do is replace the batteries. If your HVAC system kicks into gear after you replace the batteries, great! If you replace the batteries to no avail, there’s a distinct possibility that you need a new thermostat, or could have other mechanical issues with your system.

You’ll need to call a trusted Coolray HVAC technician who can diagnose your system and thermostat and replace it if needed and ensure that it’s appropriately wired to your system’s components.

#3. Drainage Issues

Below the furnace/air handler cabinet that houses the filter and evaporator coils of your HVAC system, there is a drain pan, emergency drain pan and a PVC discharge pipe that expels the condensation from your system. This discharge pipe can become blocked from algae and biological growth causing a blockage which can shut your system down and possibly even cause a minor flood. If you don’t have an emergency condensate overflow tray or if there is a clog in the drain line, you’re likely to see a puddle of water around the filter and evaporator coil cabinet. As well, a clogged condensation pump is one of the main reasons your HVAC system will shut down unexpectedly. If you discover that you do have a clogged pipe and your system didn’t shut off, it would be a good idea to ensure you have a cutoff switch such as a float switch.

An HVAC inspection from the Coolray experts can detect a clogged drain pipe and check for a cutoff switch. Give us a call.

#4. A Dirty AC Filter

A filthy air filter prevents the flow of cold air and refrigerant through the system, which forces your air conditioner to work harder. The good news is that you can usually deal with this problem on your own. If you have a disposable filter, follow the manufacturer’s instructions and replace it regularly. If you have a permanent air filter, you can wash it yourself.
