Description of Work: We spoke with MANY service providers before deciding on John Lock. They installed a replacement A/C unit, furnace, wi-fi thermostat and air cleaner. They let us know about a rebate for energy star and even helped fill out the paperwork. After making first contact on Tuesday, the bulk of the job was done on Friday; they just needed an extra hour on Monday morning to install the thermostat. They arrived promptly and were very professional. We won't go anywhere else!

Over all the entire project went as scheduled with no issuses. I'm very satisfied with the company, their employees, the products and service provided. I would recomend this company to anyone, and I would certainly use them again myself.
Description of Work: John Lock Heating and Air Conditioning (716-894-6400) was contacted by me after reveiwing several other companies. The work I required was to remove an exiting hot water heating system with a new hot air heating system, complete with air fiter, centeral air conditioning, humidtfier, and state of the art thermostat.The owner called me the Friday before and told me the time when his crew would be here on the following Monday, and also his cell phone number if there were any issuses. The three men crew arrived on time,and introduced themselves, and told me what would occure and when. The crew was polite, knowledgeable,always on time, cleaned up the area they finished work in, and always took time to answer any question I had. When the work was completed they ran a complete functional test on the system, and took the time in detail to show me first all the componets of the system and then spent a great deal of time showing how to operate it.

The installation went very well. The crew was prompt, polite, and efficient despite the fact that the installation occurred during three sweltering days. The crew also cleaned up very well. This upcoming summer will be my second with the A/C, so we'll see how happy I am with the installation this time around. So far, so good, though!

Excellent experience!
Description of Work: Installation of air conditioning and boiler . We started out adding air conditioning to our house. We have a two story house that has a baseboard hot water system. We needed all new ductwork and a unit in the attic and basement. Mike Lock gave us exactly what was needed for our house. His crew was very courteous and prompt and always left for the day with everything cleaned up. They were very easy to talk with about how the system would be installed. The quote was what they said with no hidden costs. They finished in a timely manner and always told us ahead of time when they would or would not be coming to work. We are extremely happy we chose this company as they exceeded all of our expectations. Paul, John, Paul couldn't have been nicer and more professional working in our home. As they were installing our air conditioning system we also had them replace our 35 year old boiler. My husband had purchased the boiler quite a few years previous but never installed it. After seeing the work they were doing on the air conditioning we decided to have the boiler also installed. We have the utmost respect for this crew and would recommend them with an A++++ rating!

My furnace stopped operating and when I took the front cover off it would start but then stop running again. I called and described the problem and a serviceman came at the appropriate time. He checked the furnace and listened to my description of the problem. He checked the furnace and thermostat and cleaned the furnace and ran it to be sure it was working. All seemed fine. He also remounted my loose digital thermostat. . When he was finished I asked him what the problem had been and he said it just needed a cleaning. After he left the furnace kept starting and stopping like it had done before. I called the company and was told it sounded like I needed a new part (I don't remember which part it was) but that it was not in stock and they would bring it the next morning. The same serviceman arrived as promised and when I explained what was happening he took the front panel off the furnace again and I pointed out that only two of the and quot;jetsand quot; were firing up. He said I did not need the part they had ordered. He checked further and cleaned the rest of the and quot;jetsand quot;. There were no further charges. The serviceman was polite and worked quickly and appeared knowledgeable. I would have given them an and quot;Aand quot; if it had all been accomplished in one service call.
