I switched to KNOW Heating after using a big name company that I did service with for almost 10 years. The big name company with fancy commercials on TV And took monthly service amounts to "make it easier" for me. 2 years ago they said that I needed to replace my ENTIRE air conditioning unit that they had been servicing for almost 10 years. The unit was only 11 years old at that point. They tried to sell me a new one for $9k!

I decided to get a second opinion and had 3 different companies come to check the unit. THERE WAS NOTHING WRONG. They said someone had loosen up a valve and all the antifreeze was gone. Needless to say I was almost the victim of fraudulent business practices. I dropped my contract and have been with KNOW ever since - you WILL NOT find a better HVAC company with amazing customer service and integrity. Ask for Scott! I have referred 5 people since then and they all love the service.

I love this company. I have been using them for about 7 yrs for furnace, air conditioner maintenance, and the issues that have come up with them. From the phone call to the appointment, I've only experience polite, professional and quick service and then some. It's so nice to have that resource when you live in an old house. Side note: I just read a lot of the other reviews. Jeremy, what is up with one star when you ended saying you were a fan for life?

Another low star review was for turning off furnace because of a carbon monoxide issue. He was legally bound because of his certification. Who does that? I'm not related to this company in any way, just think it's unfair.

Scott came by and while he was friendly he turned off the furnace in the crawlspace without saying anything to anyone. Who does that? This isn't your property! While I do know why he did it, that furnace has been going for almost 2 years, yes it's bad, but no one asked you to turn it off. Will pass, besides the amount quoted was not only obnoxious high, but almost enough for me to buy a smaller house.

No thanks Edit: My husband may have been there but he didn't catch it. That's something that should have been said and stated. We have also had two other companies come and and look at it. Not one has done what you did. Don't be proud. Once again, no thanks.

If you are looking for an HVAC company, look no further. I can't say enough good things about this company. There isn't a question they can't answer. Their technicians are professionals in the truest sense of the word. On top of that, very kind, courteous, friendly, won't rush you, will answer all of your questions, will give you the options and let you decide (not pushy), and as trustworthy as they come. This is only contractor I have used where I won't seek a second opinion. Don't bother researching any more - if you need help with your HVAC, KNOW is the way to go!

The most knowledgeable folks in the industry. They pick the best option for YOU! In all my years of working with KNOW this has coincidentally been the cheapest option for me. For example, when I purchased my home 14 years ago a well k own competitor insisted I needed a new furnace. I got a second opinion from KNOW. I still have that furnace! They do regular maintenance and service. It's rare to trust a company so much. Whatever they say. Do it.

KNOW heating has been taking care of our HVAC and they are the best. Scott has been our tech the last few visits where he's done work on our furnace, cleaned out our ac unit, and otherwise maintained our older HVAC. Reliable and competent service. Highly recommended.

My thermostat stop working. Apparently there is was a wiring issue. The solution was to just replace the thermostat with another battery operated one. As with my complaint with plumbers and electricians. COST I own multiple properties and I've never been satisfied with what I pay for service. Maybe I can share my grief with other people. The retail value for the thermostat was $60. I was charged $300 to simply switch it out. But what am I gonna do?
