Description of Work: Our 30 year old furnace died. They answered the phone while other heating companies had an automated response. I wanted a live body to tell my problem. They were prompt, analyzed the problem, and installed a new Trane unit. |Price was right.

Description of Work: Vendor wanted to charge $800 to replace a circuit board which was not causing the problem. For the price of a service call for what was expected to be under warranty for an AC system installed in July 2013, they have lost a customer.

Description of Work: Fixed a refrigerant tube inside the compressor unit that was the result of what I thought was a design flaw because it vibrated against the outer cover until a hole wore through and caused a leak. The technician identified the problem correctly and had to come the next day with part to fix. All was OK, I just didn't appreciate having a unit that I paid a lot of money for that was less than 1.5 years old spring a leak b/c what looked to be a design issue that could be avoided with perhaps some insulation.

Description of Work: April 14, 2014 was my last "free" seasonal maintenance check. I purchased a Mitsubishi duct-less air-conditioning system with a heat pump included in February of 2013 from this Chilltrol One-Hour Heating. The system has been wonderful. It was meant to supplement, not replace my regular natural gas (radiant) heating system, but it did replace a 25,000BTU window air-conditioner. I had three interior units installed which gives me precise zone control in those three areas, which account for about 80% of my lower floor. The installation was completely professional and I was totally satisfied. The maintenance checks have been performed professionally and courteously. I feel comfortable recommending both the system and Chilltrol One-Hour Heating.

A Trane (AC/Heating company) representative was at Home Depot. This dealer would refer the jobs to Chilltrol, which is near my house. The company is very busy during the summer months. It took about a week before someone came for an estimate, and a couple more days before the service was performed. The first person will run an estimate. It really was not a high pressure sale, which is good. The estimator was just average, he could not handle a lot of questions about warranties or furnaces. I actually had to call him several times after his visit. He claimed he had so many people calling him to schedule a servicing. He was forgetful in calling me back to answer my questions, so I had to chase him down a lot. When the repair people was working, they did not use carpet protectors like they used in the video. In the video it shows the estimator making using a special device to see what size unit you needed. I never saw this done. One of the workers use our bathroom with out asking.
Description of Work: The outside central air unit was replaced. A new coil was placed in our furnace. Our unit was out during the hottest days of the summer. All in all, we are pleased with our product. No problems so far. There were a few inconsistencies in their practices that were their selling points, that they did not do (described below).

I was extremely pleased with the work this firm performed and the quality of product they installed. Joe Pasko was the man I placed my order with, and he was very polite, knowledgeable and listened well. The installers showed up on time, did a thorough, professional job, and cleaned up so that you couldn't tell they had been there except for the unit they installed. Everything works better than I expected, and each individual I dealt with exceeded expectations. The contractor came back a week later for a final quality and customer check at no charge. The unit, made by Mitsubishi, does its job quietly and efficiently (SEER rating of 17). I can now use the sun room all year long. Chill-Trol met every commitment and did its job on time and within budget. I highly recommend Chill-Trol, Inc. I believe I got a good value for my money, but I really can't tell if the price is competitive or not. I gave them a B but it might be an A. They came so highly recommended that I didn't look elsewhere.
Description of Work: The contractor installed a combination heat pump and air conditioner in my sun room, including both a wall unit and an outside compressor unit, all wiring and related items. Chill-Trol did a thorough diagnosis to properly fit a unit with the right amount of heating and cooling power. The unit itself and the remote control it came with have performed flawlessly ever since. I can't believe how quiet it is.
