"The professionalism of the technicians and staff is impressive. I don't believe I've ever experienced this level in any other enterprise. Every need was anticipated, every question answered. Everyone was friendly, as well, and not the usual platitudes which on the surface meet the criteria. Every contact I had came across as sincere."

"Needed gas fireplace maintenance. They came by, diagnosed the problem quickly, told me the part to order and said that I could actually fix it myself when I get it - no charge! But when I received the part from Amazon I asked them to come back to install it. Their office is only about a mile from my house in Fairfield, but the day they came they were working in Berkeley - obviously very popular! They showed up, put the part in, did a little troubleshooting, and we had a working fireplace again! They were very nice and professional and inexpensive - I would definitely hire them again for any HVAC problem. Lucky to have them so close."

"Antonio did a fantastic job. He cleaned every HVAC vent and ducting, the dryer vent and replaced the ducting between the dryer and the wall connection, all bathroom exhaust vents and the furnace blower and exchanger. Super clean. I was amazed on how much crud cam our of our systems. Excellent attention to details."

"Rick replaced my HVAC system. The process was seamless. We scheduled an appointment to inspect the existing system, and the available options were openly discussed. All of my questions were answered in a timely manner. There was no pressure to choose one system over another. In comparing his estimate to other companies, I found that I'd saved a lot of money. We discovered an incompatibility between the new equipment and the yet to be installed alarm system. Rick worked closely with the alarm company to make to marry the two systems. We gave the go ahead and the new system was installed in a day. The installation crew was polite and professional and so very careful to clean up afterwards. Thank you, Bragg Home Services. Yes, I recommend this company"

Heating and Air Conditioning FAQs, answered by experts

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.
