They were great. The company called me 30 minutes in advance of him arrival as promised. The service technician was very polite and seemed very experienced. I have used this company for about 10 years.
Description of Work: The service representative checked my furnace and humidifier to make sure they were functioning safely and were not in need of repair. They checked the air conditioner in the spring.

They came in for a tune up of the air conditioning unit that we had bought from them in 2010. I used them because my neighbor had used them and she really liked them. I can’t qualitatively tell whether the service was really good. The person in this company from whom I purchased the air conditioning unit seemed almost disinterested in the transaction. He didn’t have a really great bedside manner, but the technician who came out to check on the unit was really great and did a good job. It is a feeling from that interaction with the actual salesperson that makes me kind of cold. I would most probably use their services again in the future.
Description of Work: I used the services of Air Treatment Co. in September 2011 for a tune up of the air conditioner.

They last came out a couple months ago to perform fall maintenance on our furnace as part of a maintenance contract. They also come out in the spring to check the air conditioning. I've been using these guys for over twenty years, and I give them high marks all the way. Great company in every way!

The person they sent, who had been to our house less than one month before did not know how to fix the unit. After fixing the expensive part, he realized in may have been a simple clogged hose, and checked that AFTER he replaced the other part.
Description of Work: They came to the hopuse to repair a humidifier that they had installed and had serviced less than one month earlier. They sent the same technician who had been there even though we expresly asked for someone with more experience. The person sent had to call the office to find out how to repair the service. Dispite having a Service Contract and having purchased the unit from Air Treatment, the cost was $250.

They are local, I know the technicians and I know the company. I have a service contract for a whole year, but it is only for maintenance not full service. In the spring they check the AC and change the filters. In the fall they change the filters for the humidifier, etc. They just make sure it is set to go for the season. The price is comparable and they come when they say they will.
Description of Work: I've used Air Treatment Co for 25 years. They come twice a year, in the spring and fall, for routine maintenance.

I was happy with their work. They accommodated me. I asked it they could do it that day and they were able to, which was nice to get it out of the way. I am happy with them except for one thing. The guy that came here who gave me their card, their main sales person, I contacted the guy by email. He wanted to meet with me but he was really busy and I told him I was busy too and let me know when he was available, and he never got back to me. That's the only thing that irritated me, that he never called me or sent me an email. I just suspected that they were getting bombarded by calls because it was in the heat of the summer and everybody was having trouble with their air conditioner and I just feel off the radar. You just always appreciate it when people remember when you ask them to call you. It was just a minor irritation.
Description of Work: They replaced my water heater and inspected the air conditioner. They looked at the AC and told me that it's amazing it's still running. They said its got compositors that are nearly blown and they don't really know why it's working. They recommended replacing, but we managed the unit until the end of the summer. We are trying to defer until next year. Also included a plan where they will come during the year if I need work done. Also, replaced aging line that was beginning to fail.

Great Service. Polite Technician. Excellent Experience.
Description of Work: We have an annual service agreement with Air Treatment and have had one for about 18 years or so. Yesterday the furnace would not come on when the temp in the house dipped to 64. I called them Tuesday morning to see if I could get service. They sent someone out the same day and also said that they would go ahead and perform the Fall scheduled maintenance while they were there taking care of this problem. Turns out a bird had gotten into the blower and died. The Air Treatment technician removed the bird, did the fall maintenance and they did not charge any extra for removing the dead bird since they were there for the fall maintenance call. That's what I call Service!

The technicians were right on time, polite and professional. They offered to come on a Saturday, to accommodate our busy work schedules. Overall, we were very satisfied.
Description of Work: They removed our old central air conditioning unit (coil, compressor, everything) and replaced it with a new high efficiency unit. The job required a fair amount of unanticipated duct work, and the technicians were able to handle it with no problem, using a mobile workshop in their van.

Work was performed on schedule, and the technicians were very professional. In addition, they placed protective covering over carpeted stairway and floor. Cleanup was thorough. Overall, we are very pleased. We had three estimates, and Air Treatment's price was in the middle. However, each estimate was for a different A/C manufacturer. We felt the Lennox system was superior to the other two so we feel we received a good price.
Description of Work: Removed existing A/C system and installed new Lennox A/C System. Work included moving compressor location from rear of home to side of home. Also included replacing flue pipe and damper.
