"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"

"The BEST phone call I have made this year for a service needed in my home was to Mirsky Heating and AIr. I called in the middle of a So. Cal heatwave because my thermostat had stopped working and I needed to replace it. How often does an AC company, in the middle of a heatwave, tell you they can come the same day? NEVER!! Except for Mirsky..Darrow told me that he would try to make it work..and he did...which I will be forever grateful!!! He checked in with me during the day to assure me that he was coming and not to leave work until he was more clear on the time he would be at my home. He showed up with another Mirsky employee named John..they were both super friendly and so helpful. Darrow found the problem and within 45 minutes, the thermostat was replaced and everything was up and running again. I can't say enough how grateful I am to Darrow and Mirsky Heating and Air...I am giving their contact info to all of my friends and will be calling them again for anything heating AC related."

"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

Repair costs range from $200 to $800, depending on the issue and required parts.

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

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).

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
