HVAC Maintenance: When to Call a Professional

Has your HVAC system stopped working correctly, or shown signs of needing repairs?

Maybe you’re a little tight on cash this week, and can’t afford to call the repairman at the drop of a hat. Can you fix it yourself, or should you pick up the phone?

The good news is there are some steps you can take in repairing/maintaining your HVAC system yourself which will often help significantly. The bad news is that past these steps, repair of your system can become dangerous to untrained people. It’s because of this we want to include this warning:

Do not try to repair or work on your HVAC system beyond these steps! Call a professional. A visit from your local specialist is always cheaper than a personal injury!

    • Examine Your Thermostat: Replace the batteries in your thermostat, and test it by setting it ten degrees colder or warmer than the outdoor temperature. This can be an important small fix, as your thermostat is the brain telling your HVAC when to work.


    • Check The Circuit Breaker: It is possible that power is not getting to your HVAC system because of a tripped circuit. Flip the switch, and check the master switches on the inside and outside units to make sure they’re receiving electricity. (Even if flipping the switch works, we suggest you consult an HVAC specialist. Most will be willing to explain why the circuit is being tripped.)


    • Press The System Reset Button: Resetting the unit can fix some minor mechanical hiccups which could cause the system to act irregularly. It can be surprising how useful this step is!


    • Change Your Filter: Dirt build up in the return vent of the HVAC system can cause issues for the device and waste money while the machine is working harder to regulate the temperature.


    • Clean Up Around The Unit: Clear anything that could be obstructing airflow; grass, ice, as these can have the same difficulties as the step above. You can even buy a commercial grade coil cleaner, but remember, do not open the unit! Working inside the casing could cause damage to both the unit and yourself!


    • Moving The Furniture: It’s important to make sure that vents are also not blocked or obstructed from passing air from one place to another. It’s pretty common to have a vent under your couch that you don’t know about, so investigate!

So you’ve tried all these things, and nothing’s changed! Your unit is still working poorly or not working at all. Well, at this point, it’s time to call a professional.

Remember to take note of all the symptoms of your dysfunctioning unit for the service-man to get the problem solved as quickly as possible, and always remember to perform maintenance in between repairs!
