"Within 5 minutes after Roy walked in, I knew I was speaking with an expert. He talked me out of wasting money on what I wanted (getting rid of boiler and replying on furnace) telling me about how everyone in the city during -40 degree nights was will freeze and if I keep the boiler I'll be comfy. He also talked me out of choosing a heat pump, saying in Chicago it will cause problems in the dead of winter and then I'll be out of luck. Initial estimate was only to replace the 60 year oil leaky boiler and 40 year old loud AC and furnace. Came in, did the work quickly, and when we were doing final inspection he pointed out where my last remaining original furnace was having problems. Gave me a great price to just get the the last furnace and AC done (AC was 40 years old). I know they won't be the cheapest but if you want someone you can trust who will guide you with his 30 years of experience and teach you the finer details of heating and cooling while delivering quality work, go with Porterhouse. I won't trust anyone else."

"The installation was done when promised and completed on time at an excellent price. I needed to call the installers out to take care of 3 issues that I found when checking the installation. This was done in a timely manner. Overall I am pleased with the new system although I have not had an opportunity to really test the A/C yet as the weather turn cool and it has not been needed."

"We were referred to Pustai by a friend after our regular guy decided to retire early last year, at age 82. They are wonderful to work with and we feel lucky to have found a good company to work with again. We had our air conditioner installed 7 years ago and Kyle services it today and told us it was working brilliantly and it didn't need anything. This is the greatest reference, when a servicer could make something up but told you everything was running well. Kyle was even early to the appointment. The price may seem higher but that also includes a prepaid cleaning of our boiler in the autumn, service plan. We highly recommend this company."

"Nathan arrived at the time established to complete the" boiler tune up". He started his service by educating us on maintaining the boiler and how it works. Then he did a complete clean up and checked the boiler from top to bottom. After starting it he remained until he was satisfied with it's operation. Nathan was very professional! He always had time to explain what he was doing or to answer a question. We were very happy with his work and his approach to addressing his clients needs and questions. We will not hesitate to have AAA Services return for any future work.Also our son who was at the house plans to have AAA Services complete a tune up on his family's heating system."

Install Boiler questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
