“An amazing company! They installed two systems in my house about two years ago. The team was professional, and the installation was clean. I needed service today, and although we were just 2-3 weeks out of warranty, the team came and checked the system at no charge to us. Thank you, Scott! I appreciate a company that values long-term relationships with their customers. It did not go unnoticed.“

“Eric and his team did a great job for us on a recent HVAC replacement. We got great advice throughout the project as it wasn't a cut and dry type of job. The installation team was clean, courteous, and efficient. It is clear that they know there stuff and communication was great; before, during and after the project. We have since used them for some other properties as well and they continue to deliver. Highly recommend.“

“I went to high school with Sean many years ago… I was using town and country fuel and had a brand new Roth oil tank put in by my service company..town and country refused to fill it saying it wasn’t installed correctly and very unprofessional with me after 4 years of business for absolutely no reason (they must have never seen a Roth tank before) mind you the first fill up was included by my service guy it was filled without any issue by his provider… so I reach out to T&M they asked for pictures the lady I spoke with on the phone was great very professional and helpful….They came right out next day looked it over and filled me up…. And $$.16 a gallon CHEAPER…. I’m a customer of these guys for life!!!! THANKS GUYS!! HIGHLY RECOMMEND THEM“

“Outstanding Experience – Highly Recommend!

Our neighborhood recently had some re-piping done by Aqua (our water provider), which required follow-up visits to replace individual water meters. As a result, many of us ended up working with this plumber—and every single neighbor I spoke to had a great experience, including us!

From start to finish, the communication was excellent. I got a voicemail about scheduling, and when I called back, they responded right away. I then received a text confirming the appointment, and on the day of the visit, I got a reminder along with a photo of one of the technicians so I’d know who to expect. That extra touch made me feel really comfortable.

They arrived on time, were incredibly polite and respectful, and took great care while working in our home. I work from home and they were very quiet throughout the whole visit. We have a cat, and they were super careful to keep doors shut so she didn’t sneak out or get into the basement while they worked. They didn’t move anything unnecessarily and checked in before shutting off the water to make sure I had what I needed.

They were professional, friendly, and clearly take pride in their work. I offered them drinks and use of the bathroom, and while they declined, they did so with kindness and professionalism. The entire interaction was smooth and pleasant.

Several neighbors were so impressed they asked for a business card so they could call them for future work—and honestly, same here. We worked with them for plumbing, but we’ll absolutely be calling them again for HVAC and other services in the future.

Highly recommend!“

“Fantastic service, and smooth replacement of our ancient water heater. Very friendly and they know what they’re doing!“

“The Ice Man came out for an emergency furnace service after a basement flood. The HVAC tech was very knowledgeable and friendly. He took the whole furnace apart, inspected it and verified it was safe to run with no damage to equipment. He even updated the thermostat software and helped configure it in the same visit.

Very reasonable price and quick response when it was needed.“

“Sam and his crew at AAC were very professional and installed a brand new Carrier system! They kept the job site very clean and informed me every step of the way. Highly recommended!!“

“The people who work here are amazing. I'm a new home owner and very new to DIY home projects but they took 10 minutes to walk me through what I needed to do for an issue I was having.

A part I bought didn't fit, they refunded and helped me find the right one. Just all around very helpful.

Absolutely going to these guys next time I need help with a plumbing project.“

“Our water heater broke and flooded the basement on early Sunday morning. Called them and Luciano was on emergency duty. He calmly walked me through what to do, and suggested a good local company for mitigating and drying up the flood (which should ideally be done asap to prevent mold), and scheduled a replacement for Monday. Later in Sunday afternoon, with the mitigation people already at work, the broken heater was leaking some more. It was time to call Luciano again and this time he offered to come and just replace the heater ---on a Sunday afternoon! He was so nice and helpful, and was willing to take hours off his Sunday to do so. Normally they don't do new installations on Sundays. Very pleased with Luciano's going above and beyond, and being so helpful.“

“Robert and his assistant, Josh, arrived on time and quickly took care of the plumbing issues I had. When I remembered an additional issue with a second sink, they fixed that too. Great customer service at a reasonable price.“

“He replaced our blower motor this summer in a heatwave. he was wonderful and well priced.“

“I’m a happy Client.
Six Hvac did the entire heating and air conditioning system in my house, gave me an excellent price and excellent service, I love how they work. I joined the club membership that they have and for only $44 a month they change my air filters and humidifier pads, do safety inspections, check for gas and refrigerant leaks, clean the entire system avoiding deterioration, in that club they also include parts and repairs, they have 24/7 service, if you have an emergency they do everything possible to help you. The owner is a very honest person and always willing to help the client. I highly recommend Six Hvac, we have been their clients for many years and our ventilation system is excellent thanks to them. 5⭐️“

“These guys are the best! Professional, Knowledgeable and Experienced. I've used them for several jobs and highly recommend them. Very pleased!“

“AJ and team replaced our 18 year old HVAC system on short notice when it gave out during the record cold winter ‘26. George, Chase, and Connor knew exactly what they were doing and completed the job quickly, cleanly, and explained the new system to us. Absolute pleasure to work with!“

“Bob has been our “goto guy” for 20+ years. Always responsive and pleasant. Consistently delivers efficient and cost effective work.“

“John came out for the yearly contract and HVAC servicing, he was professional, super thorough, informative and we shared some laughs. Highly recommend!“
