If you love DIYing home repairs and improvements, you may even consider doing DIY HVAC- furnace and AC repairs and maintenance. But think again. DIY HVAC projects carry myriad risks. Let’s take a look at the most significant ones.


Your HVAC system needs massive amounts of voltage to run. During a DIY project, that electrical voltage can severely injure you. As a result, you could end up with astronomical medical bills. Electrical shocks can even be life-threatening. You can also cause a fire and costly damages from short-circuiting your home’s electrical connection.

Further Damage

To fix HVAC issues correctly, you’ll need to buy special tools. Without these tools, you can easily cause further damage to your system and require more expensive repairs or replacements. It’s more cost-effective to work with an HVAC professional, who will come with specialist knowledge and the necessary specialized tools.

Breaking the Law

The Environmental Protection Agency has sanctioned laws related to handling materials in HVAC systems, such as refrigerants. You’re not legally able to handle systems containing refrigerant. Therefore, maintenance tasks like checking for leaks in your refrigerant line should be left to licensed professionals.

Hurting Your Home’s Value

When you’re selling your home, potential homebuyers are likely to have a professional inspection done before purchase. If you did a DIY HVAC project and missed some key steps, buyers will likely find out. What’s more, your DIY efforts may have voided the HVAC warranty. And remember, everything that the buyer finds wrong will lower your home’s price.
