HVAC Projects You Should Never Attempt Yourself?

When your HVAC system starts malfunctioning, it might be tempting to try to fix it yourself. These appliances are more complex than other house items. You should never attempt to repair your HVAC system if you’re not a trained HVAC technician because you could injure yourself, damage the system, void the warranty, or even break the law.

You’re far better off hiring an HVAC contractor to help you. Here are HVAC projects that you should never try, along with a few tasks you can safely do yourself.

HVAC Projects You Should Never Try

Switching The Stove From Electric To Gas

Switching from stove to gas may sound simple, but it’s not. You need two professionals to complete the project: a plumber and an electrician. You need a plumber to help you connect the gas line to avoid leaks. Without proper installation, gas can leak and cause dangerous emissions. Also, an incorrect electrical connection can get you into a lot of trouble.

Asbestos Removal

A project like replacing insulation is not challenging, but you could be dealing with toxic contaminants like asbestos if your house is old. Asbestos is used in industrial applications. It was ban from use in the late 1980s because it’s a carcinogen and poses health risks since the fibers are airborne. If your house was built in the 1970s, do not attempt to DIY any HVAC system. It’s best to hire an HVAC contractor to remove the old insulation or other asbestos products.

Repairing Your HVAC System

Trying to repair your HVAC system yourself may look cheaper to you but can be more damaging. For instance, the freon found in the refrigerators and air conditioning units does contain health hazards. If leaks, it can cause Asphyxia, Dizziness, Cardiac arrhythmia, and Respiratory problems. Also, you will be void the manufacturer’s warranty if you repair your HVAC system yourself because manufacturers don’t want unlicensed or untrained personnel working on their equipment.

Replacing Or Repairing A Hot Water Tank

You can’t replace or repair your water tank because it requires permits, code checks, and safety regulations. Carbon monoxide emissions are possible when replacing or repairing a hot water tank. Your water heater can leak the carbon monoxide byproduct if not correctly installed, putting you and your family at risk. The unit must be adequately vented, and lines need to be sealed correctly to avoid any buildup of fumes. This type of repair or replacement requires a professional.

Major Electrical Repairs

DIY your home’s electrical system can be dangerous. You’re putting your life and your family at risk when you attempt to work with electrical components. You need a professional to carry out electrical upgrades and modifications. Electricians undergo years of training, keep their knowledge base up-to-date, and can safely perform any electrical repair work you need.

HVAC Projects You Can Do Yourself


Fortunately, there are so many HVAC projects you can do to keep your home. Here are some tasks you can take on yourself:

  • Unfreeze your air conditioner: Your air conditioner can freeze. However, you can diagnose this problem and solve it without calling in the pros.
  • Troubleshoot your thermostat: If your thermostat is not working, check the batteries. If the batteries aren’t the problem, you can check the setting on the screen.
  • Check your breaker: Your breaker could have tripped if your unit didn’t come on at all. If you have different appliances on the same breaker, everything will trip, and your HVAC system will not operate. You can save money, frustration, and even embarrassment by switching on the breaker.
  • Clean your ducts: Your ducts can get dirty, just like your HVAC filter. Dirty ducts jeopardize air quality and block airflow. Fortunately, there are several online DIY guides you can follow for cleaning your duct.
  • Change your HVAC filter: Filters get messy quickly because they allow debris-free air to flow. Replacing your HVAC filter can make a massive difference in the lifespan of your cooling and heating system. You can try to replace the HVAC filter yourself to ensure it runs efficiently.

When To Bring In A Professional

While do-it-yourself can help you save money, know that there’s a limit. However, we advise you ahead by vetting out plumbers, electricians, HVAC companies, and other experts before you’re faced with an emergency.

When you have a faulty circuit breaker, a leaking pipe, or an air conditioner breakdown, you’ll need to call a professional for repairs. Keep in mind that hiring a professional HVAC contractor is worth more than any hazard you face when doing the job yourself.
