"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"

"This is the second time we've called on Nick.  He answers his own service calls and was again able to come out the same day.  He arrived around his estimated time, was very thorough in his evaluation, and repaired the problems quickly in a no-nonsense manner. In my last service call to him, I had called several other providers, they were either unavailable or wanted to change out the entire system.  Nick was able to come out that same weekend day, offered a reasonable solution to my problem, and charged a very reasonable fee.  I knew whom to call this time for my HVAC problem.  I would definitely use Nick again in the future and would not hesitate to recommend him to family and friends.

"My parents were on a road trip in the middle of summer from TX to CA. Their A/C went out in the middle of the Mojave Desert. We called Precision Auto Works based on reviews. They fixed the car the next day and were extremely friendly. My parents were able to drive the car the next day, with air conditioning. The mechanics even helped to fix a few minor issues on my VW Jetta for free while we were waiting for my parent's car. Very friendly people, with exceptional knowledge about VWs.

"Gilbert was great to work with. He was on time and completed all that I needed done, which I included the replacement of a faucet, shower head and handle on a shower door. He also replaced a thermostat, some outdoor lights and repaired some drywall in the garage. I will definitely call Gilbert again when I have house projects."

"The technician was very helpful in describing what the problems were (ON/OFF dial attachment broken off and clogged water level indicator). The fix for the clog was simple/cheap/quick but the broken dial required a new front panel which required an order and revisit. Still worth the cost of the fix and much cheaper than a new dryer.

"This is the second time we hired Zohar and his people to do remodeling and construction work for us. Last spring he remodeled our master and guest bathrooms and did a great job. This time, the job was much bigger. Zohar worked with us to architect a new kitchen. He is very creative and has seen just about every kind of kitchen, so he gave us a wonderful way to change our kitchen and to open it to our den. He did computer renderings to give us a visual view of his ideas. Sofia, who runs the office, was a wonderful help. She did all of the ordering and scheduling, and even took time on a Saturday to help us shop for counter top granite and back splash tile designs. We were new at it, and her help was greatly appreciated. We ended up with a beautiful new home and an amazing kitchen that my wife and I both love. Zohar is a man of his word, and takes his reputation seriously. Whenever there was an issue, during the long and complex construction period, he had it corrected promptly, and if it was an error on his part, he had it fixed at his own expense. As the job progressed, we did expand the scope in several areas. Zohar and Sofia worked with us and provided us with delta quotes for the extra work. We are thrilled with the end product and the quality of the work that he and his team did. My kudos to Zohar, Sofia, Ruven (foreman), and Nelson who did most of the drywall and painting. I highly recommend Best Builder's Group for any remodeling needs you might have."

Boiler Repair questions, answered by experts

Regular inspections, filter replacements, and professional tune-ups keep the system running efficiently.

Air trapped in a heating system can lead to reduced efficiency, uneven heating, increased wear on components, strange noises, and even complete system failure. This trapped air disrupts proper circulation, strains parts, and can cause overheating. Regularly bleeding baseboard heaters and furnaces can prevent these issues, ensuring efficient operation, even heating, and prolonged equipment life.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Although boilers can last 15 to 20 years when maintained properly, you may run into some common problems like oil burners and transformers malfunctioning; cracks in the heat exchanger; clogs in the heating oil pump, burner nozzles, or fuel pipes; loose wiring connections; and damaged valves. Many of these problems can be caught early on during annual maintenance services. You might also have an issue with your fuel source if you have a gas or oil boiler. Make sure your other gas appliances are working or that you have oil in your tank.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.
