Taking care of your HVAC system is essential to ensure that your house maintains a proper temperature year-round. While you could do HVAC repairs on your own, many require the experience and knowledge of a professional. 

We believe it’s essential to know which repairs can be done on your own and which ones should be done by professionals. At H.E.A.T. Mechanical & Electrical, we have over a decade of experience in servicing your existing unit to ensure it lasts you for years to come. 

Why DIY HVAC Repair May Not Be Worth It 

While there’s a certain joy and pride that comes from projects you can do on your own, it often saves time and money to trust professionals for repairs and service.

Some HVAC repairs, when done by a professional, can improve equipment efficiency and quality. Many companies require your HVAC system to be serviced properly and deem self-servicing as a void in the warranty. 

Another factor to consider about DIY repairs is the chance of costly mistakes. If you don’t have the right tools or parts, a mistake could end up setting you back quite a bit in time and money. These mistakes may also create safety hazards.

Things You Can Do Yourself 

Some HVAC repairs are great for a DIY project. You can improve the quality of your system by making routine repairs and changes, including the replacement of air filters and cleaning the outside of the unit. 

Changing the air filter is an important project that should be done every three-to-four months. Some air filters last longer than others, depending on the quality, but it's always a good idea to change them out regularly. 

Cleaning the outside of the AC unit is a great way to keep your system running properly. Removing any debris like sticks and leaves from the unit will allow it to keep working efficiently for your home. 

An important part of HVAC repair is cleaning off the surface of the unit to prevent any dirt or buildup from getting to the fan blades or the coils. This will help your house maintain a comfortable temperature and keep your unit from working harder than it needs to. Consider a light cleaning once a month and a heavy cleaning every time you change your air filter. 

Services Requiring a Professional 

The evaporator coil is a key element to your system and should always be serviced by a professional. This component is responsible for pumping cool air in and taking hot air out of your home. Dirty evaporator coils make a huge difference in your home’s temperature and should be serviced as soon as you suspect any damage. 

Unresolved issues with the evaporator coils will lead to refrigerant leaks. When the coils are old and cracked, they let the refrigerant that your system needs leak through. 

You may notice that you have a refrigerant leak if your system produces a hissing noise. This is an HVAC repair that should be addressed by a professional to avoid any further damage to the system. 

Another key component of your HVAC system that a professional should always service is the fan. Fan malfunctions can occur for various reasons and can alter the ability of your unit to provide air or heating to your home.
