"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"On Monday, May 12, our A/C wouldn't turn on and was scrambling around trying to find someone to fix our A/C ASAP since this weeks forecast weather is going to be hot.  I called a few repair companies and the closest appointment is on Wednesday.  Left a message with this company and Nick called me back.  Nick came over to fix our A/C on the same day.  He was prompt, friendly, professional and got our A/C working.  I highly recommend this company and I will use their services again.

"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

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.
