"I had an excellent experience with MULTI SERVICE MECH CONTRACTING CORP. From the moment he arrived, everything was handled with a high level of professionalism. He was punctual, respectful, and clearly very knowledgeable about his work. The central A/C installation was done efficiently and with great attention to detail. He took the time to ensure everything was installed properly and working perfectly before leaving. The quality of the work truly exceeded my expectations. I’m extremely satisfied with the results and would highly recommend MULTI SERVICE MECH CONTRACTING CORP to anyone in need of reliable and professional HVAC services."

"After having another company tell me it was a Reverse Valve issue and pretty much said "good luck" as he left, I called Fenwick/Weychoff and they had a tech out by 9pm same day. The tech, Mark Wesley, not only fixed a simple issue and got my house cool that same day, but only charged me the base price for the service call. It ended up being an issue with the thermostat. Nothing wrong with the reverse valve. Thanks, Mark, and thanks, Angi, for recommending Fenwick/Weychoff! Respectful and honest. They've got my business from now on!"

"Old AC quit and we thought it just needed a charge. Called 1 hr heating and ac, set appt for next day. The tech was on time very professional and honest. Our system was completely empty he advised us that the price to completely fill the system was about a grand and told us it is our call but ultimately the system has a leak, he could fill it and charge us the price and be without ac not much longer than a season if we were lucky. We chose to just replace the system. The sales rep was out here on time the next day he was also very professional and nice, then at the end of that meeting we were lucky enough to be able to get the AC installed the very next day which was Friday. The install guys were great also! They arrived early to my surprise which I was happy about. I was quoted about 6 to 8 hrs for install and the install team was quick 4 and a half hrs later new system was in and running great. It was a wonderful experience for such a large task"

"I needed a new air conditioner and saw a promotion at Home Depot. The salesman who responded and came to my house was very patient and personable. The installers were also very personable, dedicated, and knowledgeable. Overall, the experience of having a new air conditioner and air handler with a heat pump installed was pleasant."

Heating and Air Conditioning questions, answered by experts

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
