Heating and air conditioning systems are complex units with a lot of moving parts that are tasked with performing under extreme temperatures. As a result, it should come as no surprise that HVAC systems can be prone to the occasional hiccup. 

The most common problems with HVAC units are listed below, along with the most likely solutions.

1. Dirty air filters

A dirty and clogged air filter is one of the most common problems people experience with their systems. A dirty filter makes it harder for air to flow through the unit which then forces it to work harder to achieve the same result. This in turn places undue strain on the blower and can shorten the lifespan of the critical parts, not to mention the increased energy bills you’ll experience in the meantime. 

The best solution for a dirty air filter is an easy one: change out your filters at least every 90 days. 

2. Blown fuses and tripped breakers

When the blower is overworked, it can cause a trip in the circuit breaker. This is done as a precautionary measure to prevent short circuits or damage to your electrical system due to an overload. 

Dirty filters, duct leaks or blocked air registers can all cause a system to work so hard that the circuit breaker trips. If you’ve been diligent about changing your air filters, you may need to call a professional to have your unit inspected to locate the source of the problem. 

3. Water leaks

HVAC systems produce condensation, which is then properly removed with drain pipes. If those pipes are clogged or leaky, you can end up with a build up of water where you don’t want it. Pouring bleach down the drain pipe can clean it and potentially unclog a dirty pipe, but a technician should otherwise be contacted in the event of a water leak. 

4. Dirty condenser or evaporator coils

Dirt can build up on your condenser and evaporator coils in the same way it can on your air filter. And just like a clogged up air filter, a dirty coil can reduce efficiency and force the system to work harder to do its job. 

Condenser coils are located outside the home and can be hosed off with water. Evaporator coils are located inside the home in the furnace and can be cleaned with a coil cleaning solution. 

5. Pilot or ignition problems

Pilot light or ignition switch faults can be caused by gas supply issues, wear and tear, or dirt in the pilot, flame sensor, or burners. Because they frequently include natural gas and high voltages, these issues are best left to professionals.
