"KM Heating and Air was truly exceptional in every way single way. Miguel came to quote repairing our existing furnace and quote a new furnace. He was knowledgeable, friendly and very low pressure. We ended up replacing our 11 year old furnace with a new Lennox (I wish we would have knew about KM then). We were offered a fair price for a dual stage furnace and decided to go with their maintenance program as well. When Miquel left, we brought up my garbage cans, which was way above and beyond what we’re accustomed to. Jordan came for installation and was very professional, super hard working and took the time to chat with me about the Brewers before he left. The installation looks amazing, the furnace is whisper quiet and doesn’t run nearly as often. If you’re replacing or repairing your furnace or AC (our central air is also from KM) you would be foolish to not at least hear what they have to say. We’re a customer for life."

"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 and his team were very professional. They arrived at my residence on time and spent more time than expected due to a need to replace the existing PVC venting pipe to a larger diameter. Overall I am very happy with the service performed by Bob's team. I definitely recommend his team to whoever needs heating and cooling service."

"I would give Guardian Heating and Cooling 10 stars if there were a way to do that! These guys are outstanding! They showed up, after hours, to determine exactly what was causing our problem. We had already suspected it was time to replace our boiler since it had been more than 25 years old. Steve confirmed our thoughts about replacement. He quoted a fair price and scheduled a time to come back. He showed up early with the new boiler and within hours after their arrival, we were up and running. We had a little hiccup the next day, as things seemed to be working too well. We called Steve and he was at our house in minutes. We already wondered if the thermostat wasn't able to keep up with the new boiler set up. 30 minutes later, we had a new thermostat and everything was working properly. Steve and Adam were friendly and professional. Our basement was cleaner when they left than before they arrived. Their prices were reasonable and there were no surprises, price wise. We were given a quote and that was what we paid. It's refreshing to find people like these guys!"

Install Boiler FAQs, answered by experts

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

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.

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.
