"They were VERY responsive and we had the new system installed within 10 days. Friendly, quick and responsive. Great to work with!!"

"My furnace was installed by someone else that did a very poor job. I could not replace the filter without smashing it and smashing the new one to put in. Ridiculous! I had All Temp come out and they were able to do a quick fix so I didn't have to struggle with it anymore. He was on time, pleasant. He even put up with my dog wanting to say hello to him, Definitely would hire again!"

"Marcos was our technician and he was very courteous and professional. He not only cleaned our vents but cleaned the closet where our washer/dryer resided (which is a very tight space). Marcos was very conscious about removing his shoes before entering the house and cleaning up after all of the work. He also installed cages over our outside vents. I would definitely recommend Mr. Duct and will be hiring them again for our next cleaning. Thank you Marcos!"

"Bought Amana (Single Stage) HVAC System. Our old American Standard HVAC broke. They came in 2 weeks before and replaced the Gas Valve for $600 and 2 weeks later that broke too because of the electric board. They convinced us that instead of spending more money on parts that may also break later it's better to buy a new HVAC system. They recommended Amana dual stage - Variable system but next day they called that it was a mistake to recommend that because it doesn't exist in 15" size, so now they recommended Single stage and lower the price by $500. Not only that, but they helped us and went out of way to accommodate us with price. Likewise, they fixed it during Thanksgiving weekend."

"Used Phoenix to replace a furnace and a few hot-water heaters in our multi-unit property, and we were extremely pleased with the results. Before starting, they worked with us to select an installation that would both meet our needs and fit within our budget. They also did a top-notch installation. A couple months after the install I had a plumber in the basement for an unrelated reason, and he remarked about how impressed he was with their work. Most importantly, they were very responsive to our needs, and showed a lot of flexibility. Because we have such an old (120+ years) home with so many architectural quirks, the typical installation they were planning on doing wasn't ideal, so they ended up trying something new and making additional trips to their supplier to get the parts they needed for a non-standard install that would suit us better. Overall, they did a really fantastic job, and we'll definitely reach to to them in the future."

"Dean was amazing - Very knowledgeable, detailed and provided excellent customer service. He went above and beyond and did the install same day. Highly recommend!!"

"I recently hired them for central A/C installation and furnace replacement, and the experience was excellent. The team was professional, arrived on time, and completed the work efficiently. Everything is running perfectly now, and my home feels much more comfortable."

"Rick was very helpful with selecting my new central air and furnace system. I am still thrilled with the result."

"I hired Full Efficiency to do the spring tune up for our central AC. Carlos arrived on time, wearing PPE, got to work right away with the spring tune up, and cleaned up after himself when he completed the job. He is a very professional, friendly man. We plan to have him back in the fall to prepare our furnace for the cold weather months!"

"Happy with the installation and how everything was explained."
