"On time, neat, effective. Technicians were professional, personable and flexible. I gave a "B" on cost because I may have done better if I shopped around but having the company that was installing the HVAC install the electrical as well was a good convenience and one-stop shopping."

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

Heating and Air Conditioning questions, answered by experts

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.
