There a number of problems that commonly occur with HVAC units. When the problem doesn’t seem too serious, you might think that it will be easier and more cost-effective to just do it yourself rather than calling a professional HVAC technician. While things like checking and changing your air filter can be done easily from home, there are some jobs you should not DIY when it comes to your HVAC unit.
Refilling your refrigerant
Filling your refrigerant to its correct levels probably sounds like an easy task, just like replacing the coolant in your car. But, HVAC refrigerant is completely different. It uses a gas called freon, and this material is hazardous and can be extremely dangerous when handled incorrectly. Because of this, it is actually the law that only certified technicians are allowed to handle this material, according to the EPA. Still, low refrigerant levels can cause a number of problems, so it is an important task to call in the professionals for.
Another way you should avoid refrigerant is by leaving coil repairs to the professionals. These coils can be very delicate and also contain refrigerant, so you could easily make a wrong move if you don’t know what you’re doing and cause a leak of this hazardous material.
Any electrical repairs in your home are potentially dangerous when handled by an inexperienced person. The high voltages used in your air conditioning unit make this work even more dangerous. One misstep could really harm you or your family, and it is also likely to cause further damage to your HVAC unit, making the ultimate repair costlier. Most warranties and home insurance policies don’t cover damage caused by attempted DIY, so you’ll be seriously out of pocket.
Another way that DIY attempts could cost you more money is if a poorly done repair leads to an increase in energy bills without you even realizing what the problem is. If there’s a problem with your ducts, then your HVAC unit could be up to 20% less efficient. Leaving ductwork repairs to the professionals can save you money in the long run.
