"We got five different work proposals for our HVAC replacement. The person who came to our house was very technically knowledgable. He gave us his cell phone number and gave us plenty of his time answering our questions. I think this contractor would have done an excellent job at a good price."

"I got four estimates before choosing Michael Bonsby. They were the only HVAC contractor to actually measure my house and recommended a system based on those measurements, which turned out to be a smaller and more affordable unit than my existing system. The other three just assumed the existing system was properly sized and proposed replacing it."

"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"My outside HVAC unit was no longer working, however, everything on the inside of the house was. Isac W. was able to diagnose and solve the problem in a short amount of time. Isac was courteous and the price of the service was as expected. I would definitely recommend this business for your HVAC needs."

"Outstanding service and work. Very happy I chose them. I had an air handler/HVAC unit that was old and dirty. They came in, took it apart, cleaned/sprayed/lubricated the unit, put it back together, and it works so much better. Thank you!"

Heating and Air Conditioning questions, answered by experts

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.
