Nothing can send a shiver down your spine (literally) like your HVAC system breaking down in the dead of winter. If your HVAC unit malfunctions, you’ll need to decide who to call to check the HVAC unit.

When you need help with your heating or air conditioning system, call a HVAC technician to inspect, diagnose, and perform any repairs. Let’s dig into when and why you should hire a HVAC pro to restore your home to its usual temperature.

Benefits of Hiring a HVAC Technician for Service

Hiring a professional HVAC technician for installations or repairs ensures your HVAC system is in the best hands. Here are some benefits of hiring a qualified local HVAC technician:

  • They can diagnose, provide estimates, and repair issues.

  • They’ll follow local regulations for HVAC systems. 

  • They have top-notch tools to perform repairs efficiently. 

  • Their work likely contains a warranty in case something goes wrong. 

  • They’ll follow safety protocols to protect themselves and your property.  

Can I DIY HVAC Repairs?

We don’t recommend that homeowners repair their HVAC units due to the high risk nature of working with this complex and essential system. Any task that requires replacing major parts or taking apart the unit should be handled by a licensed professional with years of experience to ensure the repairs are done correctly. This recommendation is especially true if you’re unsure of the cause of the issue, in which case an inspection is helpful to determine next steps. The cost of an HVAC inspection ranges from $50 to $700, depending on the size of the unit, the issue, and whether it’s an emergency or not. 

You may be able to DIY HVAC repairs if the fixes are simple and require minimal tools or expert knowledge. For example, you can likely replace capacitors and AC air filters yourself.

Can I Hire a Handyperson for HVAC Repair?

Although it may be tempting to hire a handyperson to save money on repairs, a licensed HVAC specialist is your best bet to ensure effective repairs. These pros are trained to accurately diagnose problems and provide solutions they can likely fix on the spot, reducing the likelihood of recurring issues and more money spent down the line. Plus, they already have access to specialized tools and equipment that may not be part of a handyman's toolkit. 

A professional HVAC specialist is trained to work with potentially hazardous materials, such as refrigerants, so they’re more likely to follow safety protocols to protect themselves and others. A professional will also be aware of your area’s regulations and codes regarding HVAC units, so any repairs or installations are done properly.

How Do HVAC Technicians Service Units? 

Technicians typically begin by inspecting the entire HVAC system, including its indoor and outdoor components. This first look helps them identify any visible issues or signs of wear and tear. Next, they’ll check the thermostat to make sure it accurately reads and responds to temperature settings. 

HVAC pros will also look at your air filters, ductwork, cleaning components, refrigerant levels, and electrical connections before moving on to the system’s fans, motors, and safety controls. 

Once an issue is spotted, the tech will know whether a part needs to be ordered and replaced or whether you need components cleaned up or adjusted.
