"These guys were awesome, everyone from sales to the installers were laid back and professional. There weren't any gimmicks and they had the best quotes and install timelines. Hands down the best experience we had. We had a new A/C, Furnace and water heater all done in 7 hours."

"We were happy with Bell Brothers from start to finish. We have an older home with an AC unit that was at least 25 years old. Bell Brothers came out, explained our option, and guided us toward an option that wasn't necessarily the most expensive. Their installers were good at what they did, and they didn't leave our home or yard a mess. We would absolutely hire them again."

"Scheduling was easy, they sent a text with tech name & picture ahead of time, and he arrived as scheduled and communicated. They communicated recommended upgrades without a pushy sales pitch. They also make you aware of anything needing immediate attention. They provide flat pricing upfront and honor those prices if you prefer to think it over before moving forward. Past experience, I know SL honor their $99 diagnosis fee no matter how long it takes, and if not fixed they return for free. They don't put you at the bottom of the list either. They return to fix the issue, even if they didn't initially cause the issue. I have used SL for complete furnace/AC replacement, warranty work, regular service, after hours, and have referred 4 new clients to them. The only reason I have this experience with SL is because of the less than satisfactory experience I had with another HVAC company. SL has come in and replaced wiring, replaced the thermostat after rewiring the thermostat didnt work. And when one wire solution didn't resolve it, they didn't give up. They offered to provide fans in the summer and space heaters in the winter until the issue was identified and corrected. NOTE: The unit SL installed at prior address has only had regular maintenance needed to support warranty for over 8 years. My recurring issues are related to an incorrect installation during new home construction by an HVAC company who outsourced installation and then refused to stand behind their product & service."

"My husband and I had spent 13 years remodeling our 1873 house by ourselves. When it came time to do our dream project of adding a sunroom, finding a contractor to do the work instead of doing it ourselves was a very important decision to us. We met with several contractors and knew instantly that John and his son Nate at Addition Doctors were the people we wanted taking on this project. John and Nate were so great to work with. They were the only company we met with who gave us a computer generated model of what the project would look like so we had a very clear vision of the end product. They were the only company to quote us the project under the budget we told them we had to work with. They kept us up to date at every step of the project and there were never any surprises about cost or timing. They had great ideas for the project when we weren't exactly sure what should or could be done. We love our finished sunroom. The quality of work and service they gave was excellent. We would highly recommend Addition Doctors for anyone who is looking to have quality work done to their home."

"Jim was very helpful and personable to work with.  I had recently moved to the Huntsville area and was unable to connect my wireless printer.   There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer.  Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS.  He was able to get the wireless connection to work as well.  He took the computer on a Friday evening and returned it Sunday evening in prime condition. 
A few weeks later I  got an error message while reinstalling my accounting software so I called Jim.  He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable.  I will definitely use his services again.

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
