4 HVAC Maintenance Problems You Should Let A Pro Repair



No matter how competent and confident you are with DIY home improvement tasks, a professional must take care of some HVAC problems. Even if you’re familiar with electrical wiring or the workings of an HVAC system, you shouldn’t try to perform maintenance tasks on your AC or heater by yourself. The parts work together in a specific harmony, and any mistakes while trying to perform DIY maintenance can cost you thousands more in HVAC repairs.

Adding Refrigerant
The refrigerant in your system is what allows the AC to cool the air. If you have a heat pump, the refrigerant is also responsible for heating the air when you switch the system over to heat. When the refrigerant is low, you may be tempted to top it off like you do with windshield wiper fluid. Adding refrigerant is more complicated than that, and a professional has the necessary tools to measure the refrigerant levels in your HVAC system and add just the right amount.

Repairing an Electrical Issue
Even if you’re used to repairing electrical problems, you shouldn’t try to repair something in your HVAC system. If resetting a breaker doesn’t fix the electrical issue, call a professional technician. The parts inside your system, like the fan blades and the coils, are delicate and you might accidentally damage them if you get too deep into the air handler. If you mess up an electrical connection inside your system, you could short out the whole thing and cause even worse damage.

Cleaning Dirty Coils
The coils in your air handler are responsible for the heat exchange process that cools the air in the AC portion of your HVAC system. They’re filled with refrigerant, and they need to be clean to do their job. If the coils are dirty, it’s harder for that heat exchange to happen. However, the coils are very delicate, and you could inadvertently cause a leak if you try to clean them yourself. A professional has the tools to clean the coils without damaging them.

Performing Routine Maintenance
Tightening screws, cleaning things out, and checking things over couldn’t be that hard, right? Actually, it can. Technicians learn specific power sequences to run your HVAC system through that let them know if there are any problems. Additionally, technicians have been trained to know exactly what to look for inside the air handler and the outdoor unit.

They can get through routine maintenance much faster than an amateur, and without harming or damaging anything. Plus, they’re more likely to see problems that you don’t know about, simply because you lack the necessary knowledge. Leave routine maintenance to the professionals.
Save the DIY projects for installing backsplashes, replacing faucet fixtures, or your own woodworking projects. Major HVAC problems always need to go to the professionals with the proper training to handle them. If you want to work on your HVAC system, tasks, like cleaning the vent covers, changing the filter, and landscaping around the outdoor unit, are all appropriate for you to do.
