"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."

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

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
