"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."

"Contact was made with Jason and he met with me for a free estimate of what work I wanted performed.. Jason and Chris were hired to service the Furnace and to install new H&A ducts underneath the house. Other work performed by the guys was replacing old and leaking waterlines underneath the house, and hauling away all the old ducts. Hauling an old Heating and Air unit on the side of the house, and doing some mason work to cover the hole. Installing a section of chain link fence and gate. Troubleshooting and replacing an electrical switch in the storage shed. Unclogging and replacing a waterline underneath my bathtub and installing a new shower head and fixtures. Also, repairing a leaking toilet bowl and replacing a rotting section of floor underneath..... Overall, the boys were excellent in their knowledge and work performance. They were easy to talk too and their work ethics was superb... I would without a doubt hire them again should and when the need arise..."

Heating and Air Conditioning questions, answered by experts

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.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000. 

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.
