They've put in a new furnace, water heater, AC, etc. They are very reliable, but not inexpensive. Everything they do is quality and they only work with quality people. I had a problem with the air compressor on our AC right after the warranty had expired. Cahill said that they work with that company all the time and that part shouldn't have gone out that quick. They said they would talk to the company and see that it is made right, and they did.
Description of Work: Cahill was last here to do some plumbing work on a faucet. We have used them for 30 years.

They did not come out on time; they were a day later. Once they did get out here to do the work, they were pleasant and fine to work with. The job they did was good. They were also good at returning phone calls.

Cahill installed my new furnaces in a professional manner and the units work very well. The annual service is thorough and complete. I am confident that the units are well maintained and not just given a cursory service. Installation of the ducts was done quickly and professionally and their advice helped me make the right decisions. They showed up to perform the work at the agreed time and completed the work efficiently. I didn't have to allocate a block of hours during which they might show up -- as with most service companies. I'm very pleased with this company.
Description of Work: I used them to install duct work in a basement addition in April, 2008. A few years ago I used them to install two new furnaces to replace my old units. At my request they installed electronic air cleaners and ultra violet light units in the air ducts to destroy bacteria in the airways. Since then I have used them to service my furnace/air conditioning units on an annual basis.

They are very professional and do things very well. I liked their responsiveness and the fact that they take their time to explain everything to you. We will have them in mind for future projects.
Description of Work: They installed a new furnace in my five bedroom, two and a half bathroom home. It works for only one level of the house. They removed the older one and took 1 day to do the job.

I am very happy with Cahill. They were very good when they came out. They were also very professional, too. I actually called them to come out and look at my hot water heater, but they referred me to another company to handle it for me. They were very helpful with that. I thought their pricing was very fair and I have no complaints or issues with them really at all. They are a great company.
Description of Work: My heating system was checked out to make sure all was working properly with it. Cahill performed this check-up for me.
