"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

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
