When there’s a problem with your HVAC unit, things can get uncomfortable quickly. That’s why every homeowner needs to understand basic HVAC troubleshooting tips! Here are five tips to try out before calling for professional help.

Check Your Thermostat

The best way to start with your HVAC troubleshooting is to check your thermostat. This is the easiest, quickest, and least expensive type of troubleshooting. If you suspect there is a problem with your unit, monitoring your thermostat may answer your questions. Sometimes, it might be as simple as you accidentally changed the settings while adjusting the temperature. If that isn’t the case, then set the temp where you want it and wait to see if the HVAC unit adjusts accordingly. If it doesn’t, check to see if the batteries are dead and replace them.

Change out Filters

This is another simple HVAC troubleshooting tip that can save you. When a filter gets dirty, air from the unit won’t be able to pass through. This can prevent the HVAC unit from cooling or warming your home. To avoid calling a professional and having them see your dirty filters, you can change them yourself!

It’s truly as simple as locating the filter on your unit, removing it, and replacing the old filter with a fresh, clean one. Filters can be found at any home improvement store and are relatively inexpensive, so it’s a good idea to keep a few extra filters on hand. Once you replace it, check to see if this resolves the issues.

When particles build up, it can block the air, leading to a lower quality of air in your home and can affect the system’s efficiency.

Clean Your Vents

When AC circulates air through your home, small particles like dirt, dust, and pet hair can get stuck and block vents and ducts. When this stuff builds up, it can block the air, leading to a lower quality of air in your home and can affect the system’s efficiency. Take a few minutes every few months to inspect your vents and get rid of any obstructions that are blocking them. If you really want to do your unit a favor, get it professionally cleaned.

Clear Debris Away from Outdoor Unit

When you think about your HVAC system, you’ll likely overlook the outside of the unit. The outside unit is pretty important though, as it is the central point of airflow throughout your home. Since it’s in the vicinity of trees, grass, and other outdoor items, it can accumulate branches, leaves, and debris over time. These things can obstruct the free flow of air into your home and affect the air quality and cooling capabilities.

So, if your unit isn’t cooling your home quite right, try this HVAC troubleshooting tip: go outside and check around your unit. Clear all the debris and remove and prune any vegetation that may cause trouble in the future.

Check the Circuit Breakers

If your AC isn’t starting at all, inspect the breaker box. It may seem obvious, but you’d be surprised how many people don’t realize the power is out until the house is suddenly a little warmer than usual. Sometimes power overloads can cause the circuit breakers to cut the power supply. So, give your breaker box a quick check and make sure your location isn’t experiencing a power outage before getting a technician over to your home.
