"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.

"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.

"We wanted to remodel two bathrooms at the house. We needed the master bathroom with shower to be made with more handicapped accessible features. We research and called Best Builders Group as one of the contractors and spoke with Sofia. It was a good and positive experience from that first call. She explained about the process of choosing them as a company to do remodeling and how to make sure they are reputable and suggested we get at least 2 additional estimates so we will have a good compressing of the work. After doing additional research and talking to other companies we called back to best builders group, explained what we wanted done and we scheduled an appointment for Zohar to come over to our home and to measure and discuss what we want to do. Zohar definitely listened to everything we wanted and he also gave us few excellent suggestions and guidance. He was completely upfront with us about the budget issue and he really worked with us on this. He sent us a detailed estimate by email. We had some important questions and we emailed him back with them which he promptly responded to. In fact, throughout the whole process both Sofia and Zohar responded and answered quickly to our questions. Zohar, who is the owner, was also very helpful any time we called and either he got back to us promptly or got a message back via Sofia. After we had decided to go with Best Builders Group, we went to several vendors showrooms with Zohar to choose the materials. Zohar listened to what we wanted and helped us in making most of the decisions as we need; he had some really good suggestions. He spent a lot of time with us and everything was put in writing; He was even given pictures of the fixtures we had chosen. During the remodel Zohar would stop by very frequently and check on the work that was performed, speak with us and ask if we had any questions. There were some changes we wanted made along the way which were incorporated into the job without any issue.  We decided to change the type of shower door and it was expensive! Zohar called his glass vendor that they work with and they came over to install the door. Sofia didn't have to do this but it was typical of the great service and positive interactions we had throughout.  The workers came on time each day and were hardworking and skilled.  We love the way everything turned out and have gotten compliments on it! We think the workmanship and materials are top notch. They also made what could be very stressful a positive experience. We highly recommend Best Builders Group and would not hesitate to use them again."

Boiler Repair questions, answered by experts

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

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.
