Don’t try to “do-it-yourself” when it comes to HVAC repair. It’s that simple. These are jobs for professionals. Trying to fix a furnace, an air conditioner, a heat pump, a blower fan, a thermostat, or any other HVAC component will lead to increased costs, poorer performance, wasted time, and possibly safety concerns.
We wish we could leave it there, but people still feel the drive to try to fix problems on their own. The internet and its cornucopia of DIY videos don’t help.
The best way to illustrate why DIY HVAC jobs are a non-starter is to look at a few of the big DIY mistakes. We’ve often run into these problems when we’re called to look into a malfunctioning heater or air conditioner. Often, the current homeowner wasn’t the one who made the error—the consequences of bad DIY repair job echo down through the years!
