"Great professional service. Showed up next day to fix my AC. They found and repaired the previous work done by another company. If you want the work done correctly and you want to pay fair pricing, call them. The previous company I used were not honest and sold me fixes I did not need and did not repair the things that needed to be repaired. I think they did this so they could continue to come out and charge me for things like adding freon to my AC but never repairing the leak which I eventually found myself. The leak was in an outside line, highly visible (once I knew what to look for). I called AC Dave and they fixed it right away and my AC has never worked better."

"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"Darrow and his team did an excellent job! During a 100+ degree heat wave, our 2nd floor A/C failed. My prior A/C man had recently retired and I was scrambling.... reviewed Angie's List and made several calls. In several cases, I found myself as caller #10 in the queue. Darrow took the call personally, however, and was able to see us late that day. As a businessman I'm used to moving slowly, assessing, considering alternatives, etc. On this occasion there was no time, had to go with my gut. Mirsky Heat & Air really came through. They spent several hours (6-9pm) testing different options but ultimately found the compressor required replacement. They were able to return a day later and install the replacement. Their price was fair, Victor (his associate) was extremely knowledgeable, their work was first rate... and their response during a crisis was a life-saver! We highly recommend Darrow and his team... they're the Real Deal!!"

"Joe was punctual, polite, and very helpful. He took a little while to diagnose the problem with the heating unit, but once he figured it out he had the part ready and the installation underway (he first told us what the part would cost and asked permission to go ahead with the repair- which I appreciated). He tested the unit when he was done to make sure it was the right fix, which it was. Then we asked if he could also look at the air conditioning unit while he was here, since it stopped working at the end of last summer. He took some more time to fix that one, which was even harder to diagnose. But, he kept testing until he found the problem, and in the end we had 2 operable units that will save us from another service call in the busy summer season. It was worth the money.

"The dealer wanted $950. Precision did it for $600, as quoted using original mfg. parts. Owner asked what else was wrong with the car and I told him that Toyota wanted to clean the injectors....well the owner here said that cleaning injectors was the biggest scam in the auto industry and went on for five minutes as to why.   When I picked it up, he said my steering was making a small knock and that was the rack and pinion and I could wait until it got worse before having it repaired.  This is a small shop but has integrity.... a rare commodity."

Boiler Repair questions, answered by experts

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.
