Only 42% of US households service their HVAC systems annually. Servicing your central air-conditioning will ensure it lasts longer. But what maintenance should you leave to the experts?

Whether you get annual servicing or hope for the best each year, HVAC systems can have problems. HVAC DIY is tempting, especially if it decides to break during the height of Indiana’s summer. But even it seems like a quick fix, you could do more harm than good to you and your HVAC!

Read on to learn the top 8 don’t for DIY HVAC maintenance!

1. Don’t: Play with Electrics

If you have a problem with your thermostat after winter, wait a moment! Central air-conditioning has a complex set of wiring to serve your home. You have to be trained to deal with the high voltage and special electric lines.

Do not risk electrocution!

2. Don’t: Handle Refrigerant 

Handling HVAC refrigerants, such as a leak or checking levels, can be dangerous. If inhaled, it can lead to poisoning, with symptoms including dizziness and headaches. It can also lead to coma and sudden death. 

3. Don’t: Touch the Air Ducts 

Cleaning air ducts without experience can lead to health problems and worsen the situation. You will expose yourself more to the contaminants, such as mold! Signs you need a professional air duct clean include allergies and dust buildup.

4. Don’t: Clean the Coils 

The evaporator coils sometimes need attention, such as if they get frozen. However, it is a complicated area to access, and you may not have the tools to fix it properly. A professional will ensure you can get back to enjoying Indianopolis’s summer comfortably!

5. Don’t: Mess with the Fan

HVAC systems have two fans, which prevent the unit from freezing. However, it is a delicate problem to fix, which requires the right tools. If you do it wrong, it could lead to air conditioner replacement.

6. Don’t: Manage the Motor

A motor repair can easily go wrong. Because of the many parts and cost of repair, leave it to a professional. It is more expensive, but will save you money in the long run!

7: Don’t: Overwork Your HVAC

It might seem like good HVAC DIY maintenance to run your air conditioner in winter. But your HVAC will not be able to manage low Indiana winter temperatures! Your compressor and other parts can get damaged as a result. 

8: Don’t: Open HVAC Systems

Opening HVAC systems do not only risk damaging the units. It can also add more damage to your wallet, as it can void the warranty! Confirm with your provider before you start HVAC DIY repair. 

Do: Call a Professional HVAC Provider!

Now you know what HVAC DIY you should avoid. Stick to cleaning the outside of units and changing air filters. Even if the repair is not on this list, check with a professional before trying DIY repair on HVAC systems!
