Perfect Timing Heating & Cooling

Update: This company went from a great experience, to the worst experience. My secondary heat…read moresource went out during the winter and I called for a service checkup. After about 15 minutes of work I was told the condenser had to be replaced due to mice chewing the electrical wires. I could understand this. Here is where the issue comes in. The technician first said it would be $3400 to replace. He then went to his truck and came back to tell my wife it would actually be $8,000, but they added a discount so I would Pay $6,000. The total cost of the whole install (condenser unit + 4 wall units) was 12,000. So just to replace the condenser is over half the cost of the initial install. I called to complain and spoke with the service manager. The service manager essentially explained to me that this was accurate because if they did the install today it would be 23,000. So they evidently had a 100% price increase. I then explained the invoice showed the unit itself as 2,000 and then labor as 6,000. He explained to me that was untrue, that due to the new invoice system they have, they can just put numbers anywhere essentially, so I should ignore the invoice. I explained my frustration and how that does not make any sense and I am not paying 6,000 for a condenser and labor. He said he understood and would escalate it higher and I would get a call later that day or the next. It's going on 3 days now and I have not heard back. This company went from one of my top rated to near highway robbery. I cannot reccomend them to anyone at this point, and will need to look into alternatives to get my heat back in the winter.

I have been a longtime customer of Mercury Oil. I try to use the Waterbury Office for my business because of the knowledge they have of my account, including preferences. This afternoon I spoke to Lisa D'Agostino regarding paying the bill for the recent A/C service call and renewing my oil furnace service contract for the coming year. I also scheduled an oil furnace service call with my preferred Technician, John Lastra. Lisa as usual took care of all in a friendly, efficient, and professional manner. read more

On April 21, 2026, T&S came to my home to do the yearly maintenance on my furnace. While they were…read morehere, I asked them to look at a slow leak I had in the heating piping system. The tech reviewed it with me and said he would let the office know what was involved. The leak was coming from a high point vent which would require very little labor and the only material would be the high point vent itself. I spoke with Jordan from their office and she told me the estimate was for $590.00 plus tax. I made a point to say that the estimate sounded really high for what needed to be done and Jordan said there was much more material and labor involved then I was seeing. I told Jordan I would want to see exactly what was being replaced and track the labor time while the tech was here doing the repair and we scheduled the repair. May 6, 2026, the tech arrived at 12:10PM, he went to the area and confirmed that the repair was just the replacement of the high point vent itself, and he was done and back in his truck at 12:50PM. A week later I received the bill for the full $590.00 plus tax, I called and spoke with Jordan who said that I had agreed to the price when I scheduled the work, I told her that's not how I remembered it and regardless the tech was here for less than an hour and only used one small high point vent so the $590.00 plus tax was really high and I asked to speak with the owner. Jordan called me back to let me know the bill had been reduced to $230.50 plus tax which I felt more accurately reflected the work that was actually performed. Jordan made a point to say that there would be a note in my file moving forward where I would have to agree in writing with the estimate before any further work would be performed, I stated I was not happy with this and that, if the original estimate had been accurate in the first place this issue would not have happened. I again asked to speak with the owner and to date I have not heard back from anyone. Jordan was somewhat confrontational and did not in any way try to resolve the issue. I have been a customer of T&S for approximately 9 years without any issues like this before. I know they were either recently bought out or merged with another company so beware if you are having work done to make sure you fully understand the scope and advocate for yourself regarding pricing. It is a shame to have to do this as I deal with many service companies and rarely ever have issues like this. On the rare occasion there is a conflict between pricing and the actual work the other companies I deal with reevaluate the work and corresponding bill and adjust accordingly without any attitude and/or statements that I'm going to have to accept their pricing in the future whether or not I agree with it. I will be looking for other options for fuel oil, maintenance, repairs and installations in the future...
