"Roosevelt was very professional and highly responsive from the estimate stage to the finished installation. He was courteous and polite, knowledgeable and professional, and he even cleaned up after himself. When you find someone who offers the highest standards of workmanship at a very reasonable price, that's a keeper!"

"Our AC went out on 7/28 late in the evening. We were struggling to find a company that had availability to come out right away, or to even get a call back from other companies. I posted on Nextdoor asking if anyone in my area had recommendations for a company, and the owner commented on my post leaving his phone number. We called and he said he could come out that night - he came out at 9:30 at night (within ten minutes of us speaking to him on the phone). He was able to diagnose the issue, and had the AC working again within less than half-an-hour. He wasn't going to be able to get the needed part until the next morning, but he got our unit working in the meantime, and the next day sent a text exactly when he said he was going to, and showed up when he said he would, and got the work done timely. He was incredibly pleasant, and kind. Pricing for an emergency service was also much more affordable than other companies we spoke to. Thanks for the responsiveness and wonderful work!"

"I needed a lock and cover for my exterior water faucets to protect against water theft and vandalism. It was urgent, but Charles didn’t know this. He responded right away and ordered 3 locks /covers. As soon as it came in, he headed to my home within hours. The job was done on time, clean, very professionally and within budget. Because I’m out of town he sent pictures of the work that was done. I later disclosed to him about a contractor stealing my water. We talked about security measures and he recommended to me security cameras that I could use for that purpose that would work within my budget and that he would install for me. Mr. Stevens did excellent work. I would use him again."

"Very well.  They arrived ahead of time, did the job quickly, and left no mess.  We had a new central air and heating system installed by them in September of 2012, which is how we have the service contract with them.  That big job was also done in a timely manner by polite technicians who left our house as they found it."

Install Boiler FAQs, answered by experts

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

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.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
