"very impressed----joe the estimator was very knowledgeable and not pushy-----gary the installer was super and very careful to clean up every little bit of dirt---mike who did the furnace tune was super ------------how often do you have a company so honest that when you ask to have a 20 year old furnace checked out----they do a very detailed check and show the details and they don't try to ram all sorts of repairs at you--they actually said everything is fine for now ( guess who I'll call when I need one }--they were right on par with 2 other companies I called for estimates----awesome job"

"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."

"Being a new homeowner, and new to the area, I started with Angie's list to try and find a reputable heating contractor. I was apprehensive to start but Matt and John were great to work with. They took the time to try and understand my needs and fully explain everything. The install went smoothly, everything was cleaned up and they made sure sure I understood and was comfortable with everything. I would use them again and would recommend them to others."

Install Boiler FAQs, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

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.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

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.
