HVAC: 4 DIY Repairs That Don't Require a Professional

When your HVAC system isn't working correctly, you don't necessarily have to call in the professionals right away. Before making the call, there are some steps to try on your own, which might provide an easy solution to some common issues. Keep the following simple DIY HVAC repairs in mind if your heating or cooling system is giving you trouble.

Check air filters

If you experience HVAC problems, first check your air filters. When these filters are clogged or covered in debris and dust, it can affect your HVAC system's performance and efficiency. If your air filters are dirty, replace them with new filters. Your HVAC system should work better with clean air filters. If not, call an HVAC company.

Keep in mind your air filters should be changed every few months to reduce the risk of HVAC problems. You might need to check and change them more often, such as each month, if you have pets.

Check the thermostat

If your HVAC system isn't coming on as it should or if it's blowing only warm or cool air when it shouldn't, check your thermostat. You might need to replace old batteries in your thermostat to get your HVAC system working right again.

Also, check the settings on your thermostat to make sure it's not turned off or set to have the fan blowing only. Adjusting your thermostat settings might be all that's needed to fix HVAC problems.

Clean the outdoor unit

The outdoor unit of your HVAC system might need to be cleaned to work properly. Shut off power to this unit before doing any cleaning. When the power is off, remove the cover and clean the condenser fins and fan blades carefully.

If your HVAC system still isn't working, have HVAC technicians inspect it for damage. Also, have professional HVAC technicians clean your outdoor unit if you're not comfortable doing it on your own.

Check your circuit breaker

If your HVAC system isn't running, check the circuit breaker. A tripped breaker could be the cause of this HVAC problem. Resetting the breaker might solve this HVAC issue, but you might need professional repairs done if the circuit breaker keeps tripping when your heating or cooling system tries to run.
