Comments: There were 2 guys at my house and this is not the first time had a centralized humidifier installation done. These guys were so fast at their work that they completed the entire job within an one and half hours. They were thorough at their work / professional / knowledgeable and were super prompt at their times committed. I would highly highly recommend this company for future needs too.

Comments: Universal Air Heating and Cooling recently installed new air conditioner and gas furnace. Smooth process from start to finish. Bill was very knowledgeable and honest about what I needed. He provided options and did not oversell additional equipment like other companies. His team installed the new systems in a timely fashion. They too were knowledgeable and were eager to teach me. They were careful while in my home and cleaned any debris. Pricing of new system was very fair for Trane. Thus far, happy to use this company and would recommend to a friend or family member absolutely.

Comments: My central air/heat unit works great! These guys are respectful and that s greatly appreciated because it matches the work they do. I have no complaints and I ll be recommending them. Thanks Universal Air!

Review Date: 02/28/2019 | Author: Mark S.

Comments: Smoothly done from start to finish, beginning with a representative who listened, then offered several alternatives including the one I eventually went with but had not previously considered (Ductless Heat Pump.) The installation was done as per agreement by two very friendly and courteous gentlemen who attacked the job and kept up their intense pace until the full installation was completed, and done well, and two days earlier than expected. Good work at a fair price. I would definitely recommend.

Comments: Best HVAC company that I have dealt with for a long time

Review Date: 10/24/2017 | Author: John L.

Comments: We're really pleased we went with Universal, after getting 4 quotes from different vendors. They're a great company to work with. Very reasonable, compared to other quotes we received. The work was done with high quality, and very professionally. Plus, they have a great financing plan. Would definitely recommend them, and will use them for future projects down the road!

Review Date: 09/15/2017 | Author: Marilyn G.

Comments: Trevor and Kevin were both friendly and professional. I received a call in the morning before they came to let me know that they would be arriving in 30 minutes. After introducing themselves, they got right to work and did an impressive job. Upon finishing, Trevor clearly explained the different aspects of the water heater. I am very pleased with the job and the cleanliness of the work area upon completion.

Review Date: 08/25/2017 | Author: David R.

Comments: Install is great. Prompt and quick install of complete HVAC unit and water heater. I will be using them on other homes our company is rehabbing.

Review Date: 08/18/2017 | Author: David N.

Comments: Bill was great. Great price, prompt service. Could not have asked for anything more.

Review Date: 08/16/2017 | Author: Jim G.

Comments: replace propane water heater. Bill provided estimate. Team arrived on schedule for the estimate and the actual job. Price quoted was the final price. Very clean and professional. Cleaned everything up and no mess left. A little trouble with trying to pay via credit card but not on Universal's end. Processing service for cards was held by my credit card company but easily resolved the next day. Not sure why.

Comments: Selected Universal Air LLC to add central air conditioning to my 1860 farmhouse after interviewing 3 other companies. The owner, Bill Leone, spent 2 hours with me looking over the house and explaining in detail how he would tackle the project. The install crew did a wonderful job; very neat and nice, polite guys, a real plus especially when they're going to be in your home everyday for at least a week! Offered me great financing too through a company called Green Sky. Highly recommend Universal Air LLC especially if your looking to add central air to an older home. They made a real success of what I considered to be a daunting project.

Review Date: 07/12/2017 | Author: David O.

Comments: As other reviewers have written, Bill and his service techs are very thorough, friendly and professional. We received proposals from four companies and looked at three HVAC systems: Lennox, Trane and Bryant. We ended up installing two new Trane propane furnaces and 5 ton heat pumps. Universal was competitively priced and even offered to modify existing gas lines to bring them into code at no additional charge. While price was an obvious consideration, the quality of the installation was equally important. Will also sign up for their yearly service agreement. I would absolutely recommend them.

Review Date: 07/05/2017 | Author: Len R.

Comments: Professional Establishment, from estimation to completion of work. Purchased HVAC and Furnace - Received estimates from the owner, Bill. I had over 1000 questions, and he responded to every text, email or phone call within a 1/2 hour throughout the entire process. When hired, everything went exactly according to plan without a hitch. Bill was personally onsite two different times to assure the work was being done to my satisfaction. Installers Trevor and Kevin were right on time both days. They walked me through everything and made sure i was OK with things BEFORE installing anything. They were very professional and comfortable to work with. Although the cost was comparable to the Big Conglomerates, the distinct difference is the concern, care and accessibility you receive when dealing with Universal, all backed with an excellent service warranty. Bottom Line: If you want a professional establishment who treats you like family, and does the job correctly the first time without issue, this is the company for you.

Comments: Great financing options and great customer service. On time and great communication throughout the process. Value is subjective, I know I got a good product so the installation and customer service is where I place value. Its to soon to see but I am confident if there are any issues they would be handled. I would recommend Universal to friends and family!

Review Date: 05/27/2017 | Author: a Neighbor

Comments: Bill and his crew were very knowledgeable. There was no pressure to make a decision on products. Phone calls/emails were responded to promptly with knowledgeable answers. The install went smoothly, was high quality work and everything was explained along the way. The crew was on site the next day to complete another project and they addressed any additional questions or concerns we had from the install.

Review Date: 12/23/2016 | Author: Kathryn C.

Comments: Universal Air went above and beyond. My husband and I wanted a second opinion on our water heater replacement, as our was starting to leak. They not only came out the same day that I called, but answered all of my questions and came in with a quote that was half what a larger chain gave us. They were able to come out 3 days after, to replace our unit. They were on time, respectful of our home, and took the time to make sure we understood what was being done and how our new water heater worked. And even when literally a half hour later I called with more questions; took the time to come back over, double check everything, answer my questions, and tweak the system at no cost. Would recommend and use again.

Review Date: 10/25/2016 | Author: Catherine D.

Comments: Bill, Red and Trevor were all great to work with. From the very beginning of the process, Bill was responsive and helpful. They showed up exactly when they said they would, did great work, and were very respectful of our home and our time. Their price was great and they didn't try to talk us into more of a system than we needed. I would absolutely recommend them to my friends and family.

Review Date: 10/13/2016 | Author: Phil Y.

Comments: Bill is a personable man who knew what he was talking about. I am particular about how things look when done. My heat pump installation was a professional job. Well done!

Review Date: 10/01/2016 | Author: Matt M.

Comments: Replacing an HVAC system is not something most people do a lot in their lifetime. In my opinion that leaves a lot of greedy contractors out there waiting to pounce on unsuspecting home owners with no knowledge and gouge them with a ridiculous price. With my background in property management I had a ballpark idea of what replacing my 16 year old furnace and central air should cost and proceeded accordingly. I got 4 contractors to quote and was quite surprised at the range which went from reasonable to obscene. The 3 things I require are honesty and feeling comfortable with a contractor (they will spend a fair amount of time in your home) quality installation with quality equipment at a fair price and showing up in a timely manner while answering any questions you may have. Universal Air Heating & Cooling did just that and more. Bill the owner was punctual and courteous. He answered any and all questions with an attention to detail that has sadly gone by the wayside when dealing with service people. He provided a detailed written quote with a fair price and model numbers. He and his crew arrived on time on the agreed date and installed the new system seamlessly. All the old equipment was removed and the area restored to original condition and before they left the system was tested on both Heating and Cooling. I was so impressed I hired him on the spot to do work at my moms house. I could not be happier to recommend Bill and Universal with confidence. Give him a call-you will not regret it!!

Comments: The owner, Bill, very responsive & professional. When his crew failed to install drain pan quite right, he came back personally & fixed it.

Review Date: 09/21/2016 | Author: Michael O.

Comments: We were very pleased with this entire transaction. Bill is a straight shooter who responded quickly to our inquiry and scheduled the initial visit in short order. When it appeared that he might be running behind, he called to let us know. He provided a thorough proposal and quickly answered our subsequent questions. The price for the project was very fair and we hired him. We set the install date and Bill called to let us know he could do the work a day earlier. This was fine with us. Bill and his crew arrived as promised and did an excellent job from start to finish. I plan on using Bill again in the future for other projects. Highly recommend him.

Comments: Our central air unit broke . They came out and replaced our out of date unit and installed a much needed additional unit as well. In this heat we were very happy about their installation ,workmanship, and fast service . We are enjoying our more efficient unit and the AC. Highly Recommend.

Comments: This company was amazing! I have never used homeadvisor before and did so on the advice of a neighbor. Within 5 min of requesting the service and stating it was an emergency, Bill of Universal Air LLC called me. 30 min after that he was at my home. This was on a Saturday! He spent 1.5 hours doing his best to at least get my AC to limp along considering it died on the hottest week this summer and we were going into an equally hot week. When it was clear that it had died he gave a verbal quote and followed that up with an official one via email within 10 min of leaving my house. The quotes matched exactly. I feel the need to mention that as some companies will tell you one thing then when the official quote comes it's a few hundred more! Not with Universal Air. Bill said if I decided to go with them and let him know before 2pm Sunday he could schedule me as early as Monday or Tuesday which was fantastic. They came on Tuesday (I chose that day due to another commitment. They would have been ready for Monday if I was.) Bill, Trevor, and Reds showed up promptly at 9am as Bill said they would. They put down their own drop clothes for me and worked very efficiently and thoroughly to get my AC installed. I really can't say enough great things about this team. I would absolutely recommend them to anyone. I would also use homeadvisor again but as far as heating and cooling needs I would just immediately tell friends, family, and neighbors to go with Universal Air LLC. Great, polite, professional guys that know their stuff! Thanks again Bill and team!

Comments: I needed my heat pump replaced. I had many quotes and Universal was able to match the lowest quote. They did the job the same week I contracted with them and even got the job done in one day!!! Much appreciated since it was one of the hottest days so far, in the 90's and humid. Great customer service and great job done!!

Comments: We moved into a 23-year-old single family home back in the fall and knew that the original HVAC system would need to be replaced as soon as we moved in for peace of mind. Because I had the time (the old system was still working), I got SEVEN estimates for different systems and brands and decided to go with Bill at Universal Air and the Trane unit. I decided to go with Bill and his company because of his personality and the way he was able to explain things, and also the quote that he provided my husband and I was the best value that we received. I also chose Trane because of the great reviews that this brand gets in magazines like Consumer Reports. I always research things very thoroughly and choose the very best product at the very best price. He was no™t the cheapest, but the cheapest is not what you want when you are making such an expensive and important investment for your home. He sold us the highest quality product at the lowest price. We decided to go with a 16 SEER high efficiency Trane unit. We replaced both the heater and the A/C. When completing the job, Bill and his team were prompt, clean, quiet, and explained things thoroughly as they went along. The system took about one and a half days to install, a bit faster than the 2 days that he initially estimated. When he was done, he went through everything with me again, explained all of the parts of the system, maintenance, thermostat, etc. He also helped me hook up the thermostat to my phone and was again patient in explaining how it worked. He answered any questions that I had and told me he was always available by phone or email. Bill and his team were friendly and polite. He was also able to fix a few other minor issues that we had free of charge. The initial quote was exactly what he charged. I would highly recommend Universal Air for your new HVAC system installed, or for maintenance on your current system. They were the best! My husband and I are very pleased and our new system looks great and runs beautifully so far. Thanks, Bill!

Comments: Bill answered all of our many questions, helping us through the maze of options. We did some on-line research about air condo systems and sizing. Other quotes offered larger systems, with options for even larger. But Bill stuck to his original sizing because "bigger is NOT better" with air condo. Installation crew was friendly and courteous, and cleaned up after themselves. The Nexia t-stat is pretty cool and allows me to control using my smart phone. Go ahead and hire these guys.
