Keep your heating and cooling systems in check by calling a professional every year. Regular preventative maintenance can help prevent significant issues from developing into bigger problems. In fact, the six most common HVAC problems and solutions are preventable with yearly checkups.
6 HVAC Problems and Solutions
A dirty filter restricts airflow and causes unnecessary work for your AC or furnace, which can overheat your unit. Even if your system never breaks down because of a dirty filter, your unit works harder to cool and heat your home. You might also feel more discomfort inside your home because your HVAC isn’t cooling or heating properly.
Replacing your filter regularly is one of the easiest ways to extend a unit’s life.
The number of programmable and non-programmable thermostats is endless. When you think your furnace isn’t working properly, it may not be the furnace that needs repairs but the thermostat setting or battery.
Refer to an owner’s manual and check your settings to get rid of errors before calling in a professional. Once you switch to using a programmable thermostat with batteries, be sure to check and replace these batteries from time to time.
In harsh winter temperatures, the water inside your coils and lines might freeze. When water freezes, it expands—once it expands, it has the potential to burst. If you find that any part of your HVAC is frozen, call a specialist like NESI Comfort for help.
Odd Noises in Your AC or Furnace
It is tricky to know when you have a furnace noise going on that needs your attention, but odd sounds may indicate possible mechanical issues. Make sure to monitor these noises and listen for any patterns in your ventilation as well. When a unit makes whining or squealing noises, there is usually a problem.
Depending on how severe the issue is, it may be time to invest in a new heating or cooling unit. In any case, call an AC professional.
Dirty Evaporator Coils
Your evaporator coils are responsible for absorbing heat inside your home so you stay cool and comfortable. That’s why it’s so important to keep them clean. Over time, dust, dirt, pet fur, and other pollutants can clog your evaporator coils, reducing their cooling efficiency and breaking it down much sooner.
Your simple fix is to turn off the condenser and hose down your evaporator coils. Unfortunately, a dirty filter can also affect your coils—be sure to replace your filter on a regular basis.
If the pollution is heavy, you will need to call an HVAC technician for a thorough cleaning.
ACs and furnaces produce moisture in the form of condensation. Your drain pipes are there to make sure all of that water drains properly. But if your pipes have clogs or cracks, water leaks are common.
Leaks need immediate attention so call your technician as soon as possible.
To avoid dealing with HVAC problems and solutions, your best bet is simply to schedule regular maintenance. With a bit of proactive care, your unit will be running for years to come!
