When you need an HVAC contractor to service the air conditioning system at your White Bear Lake home or business, you’ll want to find one that has the experience and expertise to get things working efficiently in short order. Prescription Heating & Cooling is your trusted White Bear Lake HVAC contractor.
There are lots of folks passing themselves off as being qualified White Bear Lake HVAC contractors, and you may not realize they don’t have the correct knowledge required to safely repair your system. Some of these would-be White Bear Lake HVAC contractors are likely excellent handymen or even highly qualified electricians.
Servicing air conditioning equipment is considerably different than repairing appliances or working on residential or commercial wiring. There is a requirement for a strong electrical and mechanical background, but it also requires a thorough understanding of the refrigeration system. To do it right, a White Bear Lake HVAC technician requires proper training and some apprenticeship under the guidance of a more experienced technician.
Why Hire a Professional?
If your air conditioning system isn’t working right because of a straight mechanical or electrical problem, the self-declared HVAC contractor may think they are able to identify and correct it. But, just as an example, suppose you called a White Bear Lake HVAC contractor because the unit is not moving much air, and it isn’t very cold either.
Upon arrival, the White Bear Lake HVAC contractor finds the evaporator coil (that’s the indoor coil that cools the air) is completely iced up. The experienced technician will know that there are several things that could cause this. Just a few of these could be:
- The system is low on refrigerant because of an initial under- charge,
- The system is low on refrigerant because a slow leak has developed,
- There is low airflow because of closed dampers or a blocked return air grill,
- There is low airflow because of a failed fan motor,
- There is low airflow because of loose or broken drive belts,
- The expansion valve is not working right.
There are more things that could cause the problem, but an untrained White Bear Lake HVAC contractor might have a hard time figuring out what to do in the first place. Some inexperienced technicians seem to have a tendency to start with the expansion valve, even though it’s the least likely culprit. Expansion valves rarely need adjustment or replacement, and it can be an expensive repair. It’s best to go with an experienced White Bear Lake HVAC contractor, like Prescription Heating and Cooling.
