"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"Excellent service! I had a 26yr old A/C and Propane furnace that I wanted to update to an ALL ELECTRIC high efficiency heat pump. The price in the estimate was much higher than I was expecting, but they worked with me and brought it down considerably, provided I could accept an install slot in a couple of days due to a cancellation. Go for it, I thought! Unfortunately, it turned out that the estimator/salesman (who shall remain nameless) apparently got a bit confused and set up the equipment as a hybrid propane system - not the all-electric system that I wanted. Ugh. I only realized this when the installers had the indoor unit in place, and I saw the propane burners. Doh! So, I explained the situation to them, and they pulled the unwanted unit out and jumped through the hoops to order the correct unit and its accessories (wiring, breakers etc.), with no change to the price. They were very friendly and polite through all of this even though it meant the wasted work and that they had to come back the next day with the new IDU. Anyway, the final install all went well, and they were very friendly and respectful of the property and explained all the install details as they went (sorry Melvin, for all the pestering!) I'm very happy with the company and the installer's knowledge and professionalism. RECOMMENDED!"

Heating and Air Conditioning questions, answered by experts

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

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.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

If you have the luxury of waiting a bit to replace your unit, they can drop in price depending on the time of year. Air conditioning units often go on sale in the fall after they’re not as in demand when the temps drop outside. Same with furnaces—prices drop in the spring when it starts getting warmer.
