I'm conflicted about price. We had a previous firm that had been under service contract with use for many years. When the A/C failed they didn't perform. I called around and Twin Air had the best price. They did work very well and in a very timely fashion. Not their fault, but the A/C equipment has had many reliability problems, which they took care of at no cost to me. Then less than a year ago, the thermostat failed, under warranty and they charged me more than it would have cost for me, and I'm quite capable of having done the work myself. I could have gone to the store and bought a better, cheaper thermostat, for less than what they charged me under the warranty. The cost of the system was much, much, much bigger than the cost of the thermostat. But it left a bad taste in my mouth. That I felt abused that they charged me for the time to replace the thermostat. If I balance the $10,000 of the A/C, which was a good price, with the $300 of the thermostat, which was a terrible price. i'd have to say that the $10,000 outweighs the $300. So I'd give them an A, but I was not happy. They did very good work. Every time the thing is broken they've been out here to fix it. I guess I should have complained about that price but I was going on vacation the next day and just didn't get around to it. I think if I'd have called the owner, I think I would have been given some concession. They are still under contract.

They are excellent. They are very honest and very reliable. They are my go to company. They are very responsive. I really do like them. They have come out to do repairs for me without charging me for call outs until they actually fixed it. Then they would just charge me for one call out.

We came home from vacation on a Sunday to find the AC not working. Called Twin Air based on a friends recommendation. The technician came out in short notice, within 1.5 hrs), to fix the broken AC. Replaced the blown fuse and checked all the pressures; they were still good. A couple of weeks later, the AC went down again. They came out again, very quickly. The technician noted some frayed wires within the AC unit. He fixed the wires, replaced the fuse again and checked the pressures once more; for no charge. He did mention that was something the first technician should have caught. That is why the low score for Quality.

Tolle is very knowledgeable about the business. He was the only one to do a full analysis to determine sizing of the furnace and air conditioning units. His recommendations were A smaller ton air-conditioning unit then was originally put in the house and a higher end furnace. I had no doubt that I selected twin air that the work would have been high quality. I had the sense that the company was used to working on higher and projects then my townhouse situation. The pricing of the services was on the high end of the multiple quotes that I had received.

From start to finish excellent experience. Hands down the best value (quality vs. cost) offered in town. I cannot say enough good things about these guys. The installation crew was neat and craftsmanship was outstanding. Condensation pipes and wires that were sticking out around the old furnace and coil were tucked in and rerouted neatly around the new furnace resulting in a much neater looking mechanical room. I never even thought of asking them to do it, but the Twin Air crew just went ahead and did it! After a month of living with it we absolutely love our new smart HVAC system and could not be happier with Twin Air. I recommend them in a heartbeat.

I had two other quotes that were within the same range within $200 to $400 difference both up and down. Went with Twin Air because of their excellent customer service- from the first call, the first visit, follow up visit and to the actual install- I was really impressed. The staff - the twins, the dad, the young lady answering the phone-- all were exceptionally cordial, pleasant, professional and prompt. It was so refreshing after months of poor service including one of the techs from another HVAC company that came out to look at the unit. My unit was about 20 years old and had been in stages of dying for years but finally went the first week I turned it on when the weather warmed up in May -- absolutely the same time many other people found out their units were also dying so it took about two weeks for the install. I wish that the install could have been faster but I am not sure if that was a function of the general weather timing or the company or a combination but either way I was able to work and I understand different people have different senses of urgency. Fortunately I am in a condo and the weather cooled off a little so we purchased two portable units for upstairs until the install. The other company could have installed the week before but I did not like the techs bedside manner and I am quite tired of paying through the nose to people who have no idea what it means to treat a customer accordingly. I would definitely recommend them.

We woke up after a really nasty summer storm Saturday nighto find that our upstairs air conditioning unit wasn't working. We tried calling our home warranty service company only to be told that it would be 4 days before they could send someone out. I then resorted to calling several local companies and got the same result. Finally, my wife remembered a prior experience with Twin Air and suggested I give them a call. To our surprise Jeremy, a co-owner, took our call and responded within 30 minutes. He took the time to completely diagnose the problem and had our unit up and running in not time at all. Not only did he make a Sunday house call, but it was on Father's Day as well. I highly recommend the services of this company, they are A+ in my book.

We have used Twin Air for years both to install and/or replace HVAC systems and to do maintenance on our systems. (We have five separate systems in our home.) We would not use anyone else. They are completely professional, highly skilled, and thorough in their work. They have come out more than once on short notice when we have had an emergency and fixed the problem with no hassles. Their prices are reasonable and their work is always reliable. Highly, highly recommended.
Description of Work: Annual service. Ours is a little high because we have 5 zones and a humidifier for the house. Your costs may vary.

They were really professional and they knew their stuff. They also charged less than the other company that had initially come out and had been unable to diagnose. The company came out like three times and had diagnosed it differently each time, and then Twin Air came out and they figured it out. They are first class. I was emailing with them a lot too and they seemed really responsive.

They have been very professional and helpful. They come out twice a year to maintain the system and everything has been fine. Also, the install was fine. The people are nice and answer any questions we have about the system.
Description of Work: Last month they came out for the winter inspection. They come out twice a year to inspect the system. The cost of service includes parts and is a once a year fee. We purchased a new heating and ac system a few years ago. We replaced the gas furnace and air conditioner. They put in new duct work, humidifier and new refrigerant lines. We interviewed multiple contractors and chose Twin Air. We have been very happy with the products and with their service. We chose the Lennox products for the furnace and have no regrets.

Working with Twin Air LLC was refreshing after dealing with a less reputable and incompetent geothermal distributor. Their customer service is top notch - they will call or email you back in a timely manner. Josh and Jeremy fixed my system which after two years of bandaid fixes by the installer had never been reliable and often failed when needed the most. Their systematic and efficient inspection of my geothermal system identified countless installations errors. Since they corrected these deficiencies, my system as worked as advertised and maintains target temperatures even when temperatures drop into the low teens. Thanks to Josh and Jeremy, we now have much more confidence in our system.

Twin Air installed a new HVAC system, with dehumidifier and electric air filter. Installation was delayed by Twin Air (their technicians were in training) and resulted in our loss of the $1200 rebate. The first winter using the dehumidifier, we had to call for service. The first call resulted in the dehumidifier being replaced due to incorrect installation. The following summer (one year after installation) when we attempted to turn on the AC system it was not cooling down the house. Twin Air came out for service and repaired a leak at one of their joints and charged the system. The following winter (second season of use for the dehumidifier) We had to call Twin Air for service. Although not charged for the labor we were charged for a new part for the dehumidifier. The following summer, Twin Air was called again to service the air conditioner. It took more than a week to schedule the service appointment. The service required replacement of the coil. We needed to remind Twin Air that the unit was under extended warranty and would need to be replaced at no cost to us. Twin Air was insistent that we must cover the diagnostic fee of $100. Moving into winter once again, service was required again on the dehumidifier, diagnostic and parts cost $203, even though under extended warranty. Return to summer, the AC unit was not cooling again. We reported the issue to Twin Air and notified them we were moving our warranty to another company. The new company replaced the coil and we are now into our 2 summer with no service calls. As for the dehumidifier, my husband purchased new parts and fixed the issue Twin Air could not.
Description of Work: This particular service call was to replace several part on our 3 year old dehumidifier.

The first 80 degree day of the spring and of course I turned on the AC and got nothing but room temperature air blowing through the vents. Josh came out same day and pointed out that the outside and inside unit were both frozen over. Unfortunately, there was nothing he could do until it thawed out. He proceeded to check the rest of the system and discovered that the system was installed without a filter cabinet and the duct work was installed so that the air flow to the unit was very inefficient. In addition, he pointed out that a heat pump thermostat had been installed and I have a gas furnace and electric AC, no heat pump. Also, the furnace could not be run without going outside and unplugging the AC unit otherwise they both ran at the same time. To make matters worse, because there was no filter in the system, the coil was covered in dog hair and dust. Josh took measurements for a filter cabinet and checked the remainder of the system and told me someone from his office would call me with a quote to get the system properly installed. Monday Morning I spoke with Tollie, the owner and he gave me the estimate to complete all the work and assured me I would notice a major improvement once they were finished. I told them I was a go with the plan and Tollie ordered the custom duct work be completed. Jose and Josh came back out on Wednesday and completed all the work. The young men were incredibly professional, efficient and knowledgeable. When the work was finished they were right, what a major difference. This system was installed in 2008 and it has never cooled as well as it does now. My next task is to have them out to clean my ducts. I'm sure they are a mess after 5 years with no filter! Thank you Tollie, Josh and Jose, you guys are my hero!

Excellent. All the folks at Twin Air are top notch. They went above and beyond to install things properly. They do extremely clean work and had to make a few set up changes along the way which turned out would save us money. Customer service and interaction is unmatched as far as I'm concerned.

All of the workmanship is superb, and the project was completed on-schedule and on-budget. Every aspect of the Twin Air project was handled to our complete satisfaction. The proposal phase was thorough and professional and the design incorporated all of our requirements. It also included several important items we had not considered, including a conditioned crawl space. The result is an HVAC system that keeps our new addition very comfortable throughout the year. Twin Air accomplished all of that while working within our budget and dealing successfully with a very challenging site for the installation. We appreciated the top quality materials that were installed. And we especially appreciated always being able to reach the individuals working on our project. This enabled any issues to be promptly resolved and schedules to be maintained. Everyone on the Twin Air team is extremely courteous and helpful. It is obvious to us that Twin Air is very committed to customer satisfaction and quality workmanship.
Description of Work: Twin Air designed and installed a total HVAC system, Gas Fireplace, and complete plumbing system for the new addition to our home. The work performed included all of the HVAC duct work, gas piping, hot and cold water piping, and drain piping.
