"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."

"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."

Install Boiler FAQs, answered by experts

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.

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

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
