"Ductz of the Upper Bay Region cleaned my ductwork today. The team was professional and friendly. The cost was stated in advance as a firm price and not an estimate. They took before and after pictures which I found very helpful. The owner and his team went above and beyond to suggest ways that I can best maintain my A/C system to minimize the need for cleanings in the future. I recommend them highly."

"Excellent service! Avraham and Angel were professional, thorough, and courteous. They cleaned our dryer vent, air ducts, and heater, and also installed a UV light. They took before-and-after photos so we could clearly see the results, which was greatly appreciated. They did an excellent job and left everything clean when they finished. Highly recommend!"

"Relieved - that's how I would describe working with Carroll Mechanical. Ever since another company installed my furnace 6 years ago, I don't think it was ever working right. A number of companies have come over the years but nobody was able to properly diagnose the problem until Drew from Carroll Mechanical showed up. He was wonderful from the start and had over 50 years of experience in the trade. He spent the whole morning at my house running a full diagnostic, including a detailed combustion analysis plus measurement of gas pressures, duct air pressures, air temperatures, electrical readings etc.... he explained them all to me patiently like a good doctor and told me we what we needed to do - adjust supply gas pressures and increase the size of the exhaust flue to get the right air/fuel balance. Previous companies just wanted to get in and get out, but these guys took their jobs seriously and were just lovely to deal with. Insanely smart, caring, and reasonable people."

"Brandon Brock arrived at my home this evening. He is very relatable with a keen sense of professionalism for the services he provide. I now understand how to properly clean my air filter and operate my nest thermostat. I still operate sort of old school but he encouraged me to utilized the nest app to help manage the temperature of my home. Most people use jargons, or acronym when explaining techniques, but Brandon was very patient with me and did not mind explaining anything more than once. It was a pleasure to meet him and started my weekend off in a good way."

Air Conditioning questions, answered by experts

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.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.
