Mr Sosa submitted a quote after I had rang and submitted many enquiries to many contractors for work attaching new ducting to old ducting. I choose Mr Sosa because he said he would do the work today. Other contractors made undertakings later and I needed this work done to allow other works to proceed. During the day Mr Sosa made undertakings both by phone and the message system on this website he would do the work today. I waited until 10pm for him to arrive but he never did the work. From my experience I find the undertakings of doing timely results not being met. From my experience I would advise extreme caution when dealing with Mr Sosa.

Was very professional and presented himself well. I had other HVAC companies out and did not take time to give the right options like Dan did. I am now waiting to meet again with Dan and confirm contract

Moldguys is an *awesome* small family company and I couldn't recommend them more wholeheartedly - I wish they worked in general home stuff and not just mold remediation so I could hire them for all work at my home and not deal with any other repair companies. They did a big job in my basement and cleared out a ton of heavy stuff before even being able to deal with the mold issue and their price was really fantastic, certainly the best I came across. Their hard work and great price is in addition to their really kind way with customers - I work off-shifts and they made sure not to bother me during my daytime sleep hours and were so gracious when I had to ask them for help with things and to move their truck for other contractors. They even helped the other contractors with moving some heavy stuff because I wasn't able to. This brings me to my next point - I have been working with many different contractors lately on various concurrent projects and can confidently say Moldguys were the easiest and loveliest to work with as well as the most professional - they have typed up work orders with a clear breakdown of the work and costs along with when payments were expected..just really appreciated everything about the way they do business. They worked at my home for nearly a week and endured very hot as well as cold rainy weather and just did great work. Lastly, they saved me a lot of money when they pointed out reasons I didn't need to hire a company for additional work on something.. Great people, great company, awesome customer skills, just genuinely wonderful people doing hard work and doing it WELL. Hire them if you want uour job done right by really nice people.

Jose is the best sub-contractor that I've ever hired. Not only is he timely and professional, his work is amazing. Gets it right the first time and with the most cost effective method. Additionally, he a great guy who genuinely cares for his work and customers. I highly recommend him for any hvac or small plumbing job.

Our heat pump broke down so we called a company out to take a look then they told me they can fix but the cost would be so high that they recommend that I should consider a new heat pump so I told them I will think about it . So I went on Thumbtack for a second opinion I got in contact with Remedy Cooling and Heating Remy came take a look at my heat pump run some diognostic told me that the heat pump need freion and one welding he told me what it would cost, how long the work would take , very upfront and honest very hard to find in these days . Remy did not charge me to come out and check on my heat pump and run diognostic on the unit very honest. All I can say from now and for the foreseeable future he is my go to HVAC contractor . Mark W

Henry responded within minutes after I posted my request for help with our radiator leak. He was at our house in less than an hour and he fixed every radiator in our house. I can't say enough about how much we appreciated his help. We have asked Rite Temp Heating Company to do some more plumbing work for us.

Few times in my life I write about a company. This crew came to my home last night after suffering 2 other plumbing contractors whom I told what unit I have, swore they were well versed, couldn't restore my heating system. now its 1:45 am my home now 48 degrees and fearful of a total freeze-up. Called a friend who I remembered boasting about the plumber who came over a few weeks ago to get his personal cell number. He responded in 40 minutes and worked until my high efficiency unit was fired up again. He had a computer gadget hooked up to it that the other 2 monkeys didn't have and saw the problem, corrected it and we are the better for it. Sir, a true gentleman, and a special thanks dealing with my wife and crying kids. Hire this firm if you have serious issues and send the monkeys to the zoo. Thank you Vincent, get some sleep.

I had a newer AC unit stop working on me right when it was outside its warranty. The contractor who installed it was absolute trash with whom I had a litany of problems so I tried Modern Air HVAC. I really wish I would have had these guys from the start to do the initial work. Jeremy/Modern Air came out within 48 hours of my Thumbtack request. Despite attempts to repair the unit he stopped at parts that needed to be special ordered and told me flat out that the unit that was initially installed was some off-brand POS that is essentially built to fail. He was willing to order parts for me to fix it but in the end he told me I'd be saving myself a lot of money and issues down the road to just replace the condenser with something more reliable. I did some research on my own and basically found this all to be true and the price Jeremy/Modern Air quoted me for a new unit was more than reasonable. Within a week I had a brand new condenser unit, 5 year warranty on everything, and an HVAC guy that not only knew his stuff but was trustworthy, reliable, and did the little things like reply to texts and phone calls and let you know if he was going to be running behind. All things considered it would have been hard to disappoint me based on the first company I had hired, but I really felt like Modern Air HVAC went above and beyond to make sure the job was done right and that I was happy. I highly recommend these guys for any HVAC issues!

I felt that Brandon was honest. As a lay person, I'm at the mercy of a technician or contractor and believe many blow up the charges and the work that needs to be done to inflate their price. He explained what needed to be done and why. Brandon was also very personable. He is now on my referral list should anyone need an hvac. Brandon is not making a fast buck but he is making life long clients.

Wow! I am so happy with Ace Air. I had the bad fortune to have my furnace and my central air both die at the same time. I run a business out of my house, so I needed the work done fast. Ace Air was the first to reply to my request on Thumbtack, and Eduard gave me a great price. They did the work right away and did it all in one day. They were professional and prompt and did quality work. I wish all contractors were as good as this company. I am just thrilled with their service and will recommend them to anyone who needs a great HVAC contractor.

Mike is a pleasure to work with. He did not engage in any of "salesy" tactics that other contractors do when we interacted about replacing my water heater heater. He was willing to consider all options, was very responsive and gave good advice. I was considering the hybrid option and he was providing me with all the pros and cons of using a hybrid even when he was not hired. Above all, he doesn't force you to buy the water heater from him, you can purchase your own water heater from HomeDepot or Lowes or any other place....To top all that he also picked it up from Lowes and disposed off my old water heater. I have found a great contractor for any future needs. If you want good service without being ripped off, go to Mike!! Prashant

I was recommended at first by another neighbor for painting services. They were excellent and painted almost my entire house, high ceilings and all. When I didn't like the color of one main room. No issues, he said pick another color and we will be back tomorrow for an extra day. Then I learned they provided a variety of services and they became my general contractor and build an in-law apartment. The level of attention and detail was incredible. When he sad he would be there he was, when he couldn't he always called. After it was complete we had a slight problem with the air condition, which had initially been working fine for months, I called, they came immediately and corrected it. No questions asked. I call them for everything even when last year we needed someone to take a look at what was going on up on the roof with all the snow. From Plumbing, Electricians, HVAC, Carpentry, and Painting this is one stop shopping. No need to look further. We have recommended them to many people and people always ask who did the work at our home. Also no surprising costs like some other people we got quotes from. We live in an upper class neighborhood and his work is impeccable. Ask take a look at photos at some of the work they've done. I gladly and highly recommend using their services.

He is currently doing some piping for generator work at the Millyard Technology Park in Nashua. Omer is fully certified and insured for the work he does.

Curt and his team were nothing short of amazing. They installed a brand new 3 zone heating and cooling system - including all the duct work, equipment, and removal of 100+ year old cast iron radiators + pipes - in just 2 weeks. The type of system he recommended is fairly unique (forced air over hot water coil) and I was not familiar with it. The quality of the conditioned air is way beyond expectations. They started early in the morning and worked tirelessly all day. Curt also did some quick plumbing repairs at my other property and did a terrific job. I have had several contractors in the house since the system was installed and they all want his contact info so they can partner with him in the future. I would HIGHLY RECOMMEND Prestige Heating and Cooling!!!

I was looking for an HVAC pro to do periodic maintenance for a few A/Cs, commercial roof-top type. B&N showed up at promised times and serviced the units expertly. Robert (the tech.) also correctly diagnosed and repaired a few problems which defied attempts by prior guys. I am glad to have found a new go-to guy for HVAC - highly recommended!
