"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"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."

"Matt came out in the beginning of the week to inspect our AC. Before we called we heard loud noises when the AC outside came on and that is why we called. Matt inspected our system and explained that our compressor was leaking freon and that it was down 2 lbs. Being that this AC was installed back in 2009 it was using R22 which is outlawed by the government. So in order to get this fixed we would have had to change the compressor which would have cost us around 600-1000. The other bigger issue was that when the builder installed our AC it was not sized for our home. We were very blessed that we were able to use it for 9 years before it went out. We were overworking the unit being that it was trying to cool a 1550 sq ft. home and it was only a 1.5 ton unit. So Matt proposed replacing our unit. We negotiated a great price and we scheduled them to come out on Friday May 24th. Up till now, Matt was on time, very professional and was careful on making sure his shoes were covered before walking in our home. Matt was also knowledgeable and was easy to understand. At the time my parents were visiting and he was very helpful and explained the situation to my parents. They really appreciated that. Now on Friday, Matt and Dan came out and again showing great care for our home and our time. They installed our system quickly and efficiently. After they completed the work, we noticed a huge difference with our system. The house was cooled in no time. We were very happy that we finally had a system that was appropriately sized for our home reducing our cooling time by almost half. I am so happy that we called Matt to do this work. We never felt that we were taken advantaged or that we didn't have control of all the decisions that needed to be made. I recommend Matt and his team."

"I called for service and appointment was for the next day. Service person showed up on time. The problem was found (bad micro switch) and a zone valve motor/actuator was replaced. The whole process was completed in 30 minutes. They give senior citizens a discount. Yea! I would use them again for other problems or maintenance."

Install Boiler FAQs, answered by experts

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

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.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.
