"Hired them for some electric work done in my main bathroom. There was a little hiccup with the bathroom exhaust and its Bluetooth functionality. I called the manufacturer I ended up ordering another one. It costed an extra $89 for the team to come back and have it troubleshooted. The first time around the Bluetooth portion wasn?t connected properly and supposedly the brand new exhaust had some issues. They also left the ceiling dirty, which I had to scrub and clean. Also, I let them borrow some tools that I had to call them back to retrieve. They are overall hard working and personable people, but in my opinion the quality of work and communication could be better. I should have trusted and verified their work and not just assume everything is functioning as it should be before having them leave the first time. "

"My case was an urgent one, and the Improved Comfort Heating & Air Conditioning team resolved the issue promptly and effectively that same day. It happened to be Halloween, a day when HOA staff usually leave early, yet their responsiveness was exceptional. When I called Mahdi to inform him of the situation, he arrived as quickly as possible despite the heavy traffic and repaired the heating system efficiently. Their office staff also kept me well informed about his schedule and handled everything with great professionalism. I truly appreciate their outstanding service and have added the company to my trusted list."

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 undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

When the capacitor fails, the AC unit can’t operate at all. The most common sign is the thermostat forcing the blower to turn on, but it only circulates room-temperature air. The AC unit also won’t make any noise or indication that it’s on. Sometimes, the compressor might hum as it attempts to work, but without any results.

Before a full shutdown, a faulty capacitor can cause your AC to struggle while turning on. The unit might also shut down in the middle of a cooling cycle.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
