"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."

"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!"

"A Better Way Heating & A/C - Review Matt made the situation almost a pleasure to deal with. Per my phone call, we met @ 8:00 am the day after next, at my convenience. He showed as scheduled, quoted me a price & completed the work by 10:00 am. (2 hours later) TOTAL SATISFACTION (No pressure) I deal with contractors more than the average. I am a retired building inspector & own several investment properties."

"Great company! We contacted them on a Monday evening and they were at my house by 2 pm the following afternoon, we really appreciated the quick response. The technicians sent to our home were very professional and took care to not damage our property when removing our old water heater, as well as when they installed the replacement. The cost of the job was reasonable and completely fair."

"Great, although I had to wait 8 days for the installation. It was one of coldest weeks in December and it was a good thing I had a fireplace. The installation was quick, it took less time than estimated. Installers were professional and they cleaned up the area."

Install Boiler FAQs, answered by experts

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.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

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

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
