Why DIY HVAC Repair is a Bad Idea

With the internet, it’s easier than ever for the DIY enthusiast to learn about the intricacies of the equipment that he uses every day. And most of the time, that’s a great thing. People should want to know how the things around them work. It’s exciting, and it helps you appreciate what you have more.

But HVAC systems should under no circumstances be worked on by anybody other than a licensed professional. Here’s why:

You’ll Probably Break Something

There’s a reason that most states legally require HVAC technicians to go through special training and certification programs: HVAC systems are complicated. Your air conditioner is a complex contraption of gears, chemicals, parts, and electricity. For the unit to work properly as a whole, each piece has to function correctly. If you don’t know how all the components work together, it’s easy to mess something up without realizing it.

And since the whole point of a DIY fix is to save money on some sort of repair, it seems counterintuitive to us to pursue a DIY repair that’s more likely to fail than anything. And believe us: you’ll spend more to get a botched repair fixed than if you had just called a specialist in the first place.

It’s Dangerous

HVAC certifications aren’t just for show—they exist to protect the technicians and the people whose HVAC systems get worked on.

Air conditioners use various gasses as refrigerants, and furnaces typically burn either oil or natural gas. The coolants in air conditioners and natural gas in furnaces are both oxygen displacers, which means that in a small space, they’ll take the place of oxygen. This means if you get enough of either gas in your lungs, oxygen won’t be able to force it out, leading to loss of consciousness and even death. Not to mention, natural gas is explosive.

Even if you spring a link that doesn’t hurt you, it’ll still mean that your air conditioner won’t do any cooling, which, again, defeats the whole purpose of repairing it yourself in the first place.

Also, many air conditioners are high voltage. This shouldn’t come as a surprise, since air conditioners are one of the highest-energy-using appliances there are. With this high voltage comes a very real risk of electrocution if you don’t know what you are doing. So leave it to the pros.

You’re Likely to Void the Warranty

If you aren’t concerned about your health, maybe this will sway you: by forgoing professional HVAC maintenance, you’re also forgoing your manufacturer’s warranty. If you have an owner’s manual for a Trane air conditioner or heating unit, you’ll notice this bit of text:

“The Products must be properly installed, operated, and maintained by a licensed HVAC service provider in accordance with the Product specifications or installation, operation, and maintenance instructions provided by Company with each Product. Failure to conform to such specifications and/or instructions shall void this limited warranty. Company may request written documentation showing the proper preventative maintenance.”

In other words, your HVAC unit’s warranty isn’t valid unless it was properly installed and maintained by a certified professional—and it’s on you to prove that.

A warranty is a company’s way of saying that they believe in their products. By offering a warranty, they’re telling you that their equipment is guaranteed to last a certain amount of time, and if it doesn’t, they’ll replace the part at no charge to you. But no HVAC unit can run for long without (proper) maintenance, just like your car couldn’t go 200,000 miles without an oil change. So hire an HVAC company for maintenance and spare your wallet the trouble.
