"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."

"Our nearly 40 year old boiler system had seen its last day. Steve with Guardian was easily accessible by phone, prompt, and helpful. He installed a new boiler and retooled the set up of our system. We re very happy with the service, speed of the install, and professionalism the guys showed. We didn t shop around much since we weren t interested in having too many people coming in and out of the house during the pandemic, but felt confident Steve was giving us good information and a fair price based on what we were told in the past and research we had done. I would certainly recommend Guardian to friends and family. I will update going forward if necessary since the system is currently a day old, but the house is as toasty as ever so mission accomplished thus far."

"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!!! "

Install Boiler FAQs, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

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