Troubleshooting And Repair For Your HVAC System

Posted on: 15 August 2017

The HVAC (heating, ventilation, air conditioning, and cooling) system in your home may need repair at some point and understand the potential problems with the system may make it easier to troubleshoot. When you are having a problem with the system, there are a couple thing you can check before calling the repairman. It is still recommended that you hire a professional and not try to fix it on your own but having some idea of what the system is or is not doing can help:

Determine What The System Is or Isn't Doing

If you are not getting heat or cool air through your ducts, you need to take a look at your thermostat and make sure it is on and set to the proper setting. While this may sound like a ridiculous step, the switch could get bumped easily and call a repairman in for that would cost a lot of money that was not necessary to spend. If the switch is in the proper position, make sure the unit is on and the temperature set properly. If everything is alright on the thermostat, it is time to take a look at your HVAC unit.

Checking The HVAC Unit

Go outside and locate the HVAC unit in your yard. It is a large metal box with a large fan on top of it and some plumbing and electrical connections. Have someone in the home turn the thermostat down and wait to see if the unit starts running. If it does not, the unit may not be getting power to it and not run. The first thing to check is the electrical box or breaker box in the house or garage to ensure that the breakers are all on. If the breaker for the HVAC unit is off, reset it and see if the unit starts. If that does not fix the problem, you need to have the unit serviced professionally.

It Is Time To Call The Repairman

Calling an HVAC service tech in to look at the unit may be your only option. There are many things that could be wrong with it and unless you have the tools and knowledge to check them, you should not open the unit. Explain to the service tech what you have tried and what the unit is doing or not doing, and let them look at it. They will check all the plumbing, electrical, and mechanical components and let you know what is wrong and how they are going to fix it. In some cases, it could be a frozen condenser coil that just needs to thaw or a compressor that is not working. Either way, they will most likely come and tell you what is wrong and give you a price before starting the work, allowing you to decide what to do.
