"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."

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

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.
