Check out more posts from John C. Flood




Does your HVAC system not seem like it’s not working as well as it should? Many homeowners thrive in completing DIY projects. Doing fixes and repairs yourself can sometimes save you time and money.

While being handy brings a lot of satisfaction to homeowners, there comes a time and place to let the professionals handle it. When it comes to your HVAC system, do you know where to draw the line between a DIY fix and a professional visit?

Use our guide below to better understand when you can feel safe to handle repairs yourself — and when to call in the big guns for a fix.

HVAC Repairs & Fixes Homeowners Can ALWAYS Do

Filter Swaps
A filter swap is a quick and easy change that practically everyone can do. Just make sure you buy the correct filter for your HVAC system.

Fuse Replacements
Many electrical problems boil down to a simple fuse replacement. Check your fuses and make a swap to get your unit working again.

HVAC Repairs & Fixes Homeowners Can SOMETIMES Do

Removing Debris from Air Ducts
Simple debris can be blown out or removed from your air ducts yourself. However, there may be some debris too far in the ducts for you to reach safely. If you can reach it without risking your safety, then you can complete this repair yourself.

Checking/Replacing Belts
Certain belts or other components are not too difficult to replace in certain HVAC systems. If you suspect a broken or worn out belt, check your system and see if it’s an easy swap. If it is, then feel free to make the replacement yourself. Otherwise, you may want to consult a professional.

Recalibrating Thermostats
In many cases of a mismatch between temperature setting and actual temperature, a simple recalibration can resolve the problem. If your thermostat has a reset or recalibration option, try that before calling in the repair guys for a fix.

HVAC Issues you Should Call the Professionals About

Major or Unreachable Obstructions
Some obstructions stuck in the ductwork or other areas may not be easily accessible. If you find yourself taking dangerous steps to try and reach these obstructions, you may want to think twice. You shouldn’t risk your own bodily safety to repair your heating or air conditioning.

For more complicated obstructions, call in the professionals. They have the equipment to quickly and easily remove blockages you may not be able to reach.

Electrical Issues Beyond Fuses
If your thermostat is malfunctioning or other electrical problems are affecting your HVAC system, it’s time to get a professional in your home. The last thing you want to do is risk electrocution trying to diagnose a potentially dangerous electrical problem.

Chemical Disposal/Replacement
HVAC systems may contain dangerous or hazardous chemicals that occasionally need to be replaced. There are specific steps which must be taken to safely and properly handle these chemicals.

When it comes to chemical handling and disposal, you’ll want to get the pros in for help. You really don’t want to deal with accidentally contaminating your home or the environment with improper removal or disposal of chemicals.

Knowledge is Power in DIY Repairs
Having the knowledge and understanding to complete HVAC-related repairs is always a great skill for any homeowner to have. However, a skill that is just as important is knowing when you should let the professionals handle it — for both your safety and the overall function of your system.

If you’re unsure or hesitant about a specific step, it’s best to bring in a technician or other specialist to help.
