"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."

"Harker Heating And Cooling is the best HVAC contractor we have ever worked with in 40 years. Their web site proudly says they are an “honest company with Midwestern values.” That is absolutely true. Their representative provided in-depth advice, answered our questions. and returned our messages. Their techs were knowledgeable, professional, careful, and friendly. They were on time, on call, and on budget. The service they provided for us over the years could not be better. So when the time finally came to replace our old furnace and A/C we selected them. Unfortunately, they encountered many unexpected problems installing our new equipment. Many more than they had anticipated for the job. But their representative pledged to address every one of them no matter how hard it was for them or how much of their time it took. And that is exactly what they did. No quibbling and no questions. They got the job done right. If you want an honest family contractor who stands behind what they do, and lives by those Midwestern values, then this is the company to hire. You will be glad you did.

"Absolutely a great company to work with from all aspects. We had a large project to replace both the furnace and central AC systems, and also replace the main ductwork to create separately controlled ‘zones’ for the first and second floors. With the old system the second floor was always too hot in the summer. Through research on my own I had already decided on the highest level Bryant ‘Evolution’ units for both the furnace and AC and for the new zone control. The project was too large for the contractor we had been using to service the old units, so the search was on for a factory authorized Bryant dealer to install the new system. The choice of Square One was easy. Steve the owner came for the estimate, super knowledgeable about everything with the Evolution system including the details of the zone controls, and he prepared the proposal for us on the spot. I had originally intended to go through the usual hassle of getting at least three estimates, but I already had a ball park idea on the cost from my own research and after meeting with Steve there was no need to look any farther. Also we had a special request to relocate the intake/exhaust pipes of the old system to a difficult new location because we didn’t like where they exited on the side of the house, and Steve was happy to accommodate the request. I thought early September would be a good choice for the installation since would we probably would not need either the AC or furnace during the construction, but as bad-luck would have it a hot and humid wave of weather came right at the start date. Since the project was large it ran across four days and our crew of Jeremy and Josh did an outstanding job of minimizing the time that the AC was down, and gave us frequent updates on how things were going. They called every day when they were on the way, always came on time, friendly, knowledgeable, and super neat and orderly with all of the piping, ductwork, wiring and general work area. Co-owner Lee and Shaw came to finish up the intake/exhaust (on a Saturday) and did a fantastic job also. Also they prepared all of the paperwork for the multiple rebates that were included, and Erika and Mary in the office are always friendly and super responsive in answering our questions. The Bryant Evolution system has been great also, the hot and humid week turned out to be a good test for it and it performed excellently. The house has never been so comfortable upstairs prior to this system, and the new ‘dehumidify-only’ mode is great for the humid days without high temperature. Overall working with Square One was fantastic and greatly exceeded our expectations. They have all of our HVAC business from now on and we would highly recommend them to anyone."

"Called them as A/C was not working. They came out and refreshed freon. that was $215 fee. Our A/C was old and we were advised that it may or may not last. We decided to get a new A/C as ours was 20 years old. They advised me of the different models that they work with and gave me a written estimate and let me choose. The.y also subtracted the cost of the freon from the installation cost of a new A/C. One thing that was very impressive was that they were very punctual and gave us estimated time to have work completed. We ran into many other vendors who could not seem to provide accurate information. My wife and I felt an immediate concern for our worries from Oscar. We felt our needs were met and was very happy with service provided. I appreciated the way we were treated. This is a small business that seems to go the extra mile for you."

"I have been very pleased with all the services that Master's has done for me. They installed a new sump pump, water heater, furnace- air conditioner, kitchen faucet-drain, water softener, and installed new shower plumping(faucet and drains). I join their Membership Club and have been very pleased with the inspections and maintainace of all my equipment. They also did a great job cleaning my ducts. They show up on time, are professional and thorough, they always clean up very well when done. So I plan on having a long relationship with them."

"Very prefessional and thorough. Left my place clean after the install, and even loaned me some goo-be-gone from their toolbox for a project that I was working on while they were installing my furnace. They reviewed what they did at the end, and gave me a card so that I could call with any issues. Would highly recommend Sears and their contractors."

"Awesome! We have never felt more comfortable and satisfied hiring a contractor! Brian came out within a day or two to look over the project, and then within another few days had a written quote! This was a huge project, and they handled it like no one else could. We interviewed 3 other companies and hands down, chose Arctic Air. Within a weeks time, they had removed 2- 250 gallon oil tanks, filled with oil mind you, took out the old oil furnace, replaced with a new gas furnace, and installed air conditioning! Not an easy task on a 125 year old home! Will definitely recommend to everyone!"

Install Boiler questions, answered by experts

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
