"Robert was great at getting my boiler to fire up! He found a wire that was disconnected & capped. I think that this was done, when 1 of the other pros you have listed cleaned the boiler 3 months ago. Robert connected the wire and the boiler started!"

"Bob visited our house, worked with us on selecting a unit, and provided an estimate for the work the same night. As for the installation, within two days everything was installed and one wouldn't have even known anyone was working on our house except for the new ceiling vents. He did a great job and we would hire his company again. Bob made the whole process very easy."

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

"I literally can't recommend these guys at A Better Way Heating enough. They were AWESOME to work with. Super kind, professional, explained everything thoroughly, offered us our options and respected our decisions with no pressure. Work was done quickly, and after the installation was complete, I got the personal tour of every bell & whistle of our new machine. The guys even walked through and swept up after themselves when they were done!!! I'd call them again in a heartbeat."

"This was the year my old klunker (furnace) decided to stop working. Great,just wonderful. So I picked up the phone and made a call to 1st Choice Heating. They had a technician dispatched faster than I expected. The news was not good,I needed a new furnace. I was quickly put on the schedule and my furnace was in before I knew it. Thanks 1st Choice team you were awesome from the first call to the install!!! "

"Nicely done. We have two Carrier furnaces in our old house. I phoned Air Solutions for an annual inspection/clean on both units and they had a man available the same day. Very nice tech, good communication, no issues, and they let us use the Angie's coupon on both units. Will definitely hire again!"

"Great Job, Mike was able to get to the property same day and complete full installation within the day. Worked late hours to make sure it was complete and kept in great contact from initial inspection until installation. Will definitely use for any HVAC services moving forward"

Install Boiler FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

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.
