"Jonathan and his guys did excellent work for me in replacing my boiler. I had submitted several bids to different contractors and Jonathan gave me the best price. The guys that came to my house to install my new boiler and replace my old boiler were very professional and clean. I had two problems (a water leak and cold room) since the boiler was installed. I called Jonathan recently and he sent his guy right over and fixed both problems. I highly recommend his company. I would definitely use them again."

"This is not my first review of Joe's Plumbing but they just keep knocking it out of the park. Decided to do pipe replacement on a 60 year old home do to multiple leaks. Wanted to get it done before the cold came, and Joe's did the job on time, under budget, and the quality was second to none. When they found they couldn't turn the water off from the street, they kept moving on the job and did a fantastic job. Joe's was the first called and they have not let me down yet. Thank you Ace and Reg!"

"Joe was fantastic. He responded quickly to my inquiry, stayed in touch prior to the repair visit, arrived promptly and quickly resolved the problem with my central AC. His fee was very fair. Previously another HVAC company (not from Home Advisor) told me the unit was unrepairable and needed to be replaced. I highly recommend Joeâ  s company All-in-One for your HVAC, plumbing and electrical service."

"I hired MDJ to look at the options we had with our old central a/c unit. After considering everything we decided to install a new unit. MDJ did not pressure me in any way, & they were quick to respond. Our new a/c is installed & working fine so far. It only took 3 days in total to meet up, & get the new unit installed. I'm very glad we found MDJ."

"Although their estimate was a little bit higher than other companies T. Webber answered my questions thoroughly and were committed to doing everything above board and according to code. Since I have a strict building inspector this was very important to me. The sales person, the ACCA, the supervisor, the HVAC techs, the electricians, and the office personnel were polite, professional, top notch at their jobs, and made the entire process so much better. They dealt with the building inspector for me, filed the application and several technical reports as required, and took care of every aspect of the job. I recommend this company highly for their precision and attention to detail."

Heating and Air Conditioning questions, answered by experts

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.
