Robert Heikaus2025-05-23Trustindex verifies that the original source of the review is Google. Sadly this spring, it was time for me to replace my 45 year old air conditioner and gas furnace. Happily, I found J&S Heating and Cooling (Stu and his son Duncan) to do the replacement. First, J&S are an authorized Carrier shop, which means they are installing highly reliable equipment from a trusted manufacturer. Second, I can see why Carrier entrusts Stu to represent their brand in this area. He is knowledgeable and friendly, patiently answering all questions from engineers like myself. Stu's communication, professionalism, and attention to detail in the installation were top-notch. From the clean condensate plumbing and ductwork to the careful dressing of thermostat wiring, no detail was overlooked during the installation. They left the space cleaner than they found it. J&S's Pricing was also very competitive. I contacted three local HVAC companies, and Stu's pricing was completely reasonable and transparent. He even provided options for AC replacement only, and spoke honestly with me about the pros and cons of delaying the furnace installation. No sales, just a knowledgeable guy answering questions so I could make a decision. It makes a big difference that this is a local family business. They don't spend a lot of money on billboards and radio ads, and can provide a superior service at a lower price as a result.

I have baseboard (hydronic) heating in my house and the system supplies hot water to heat potable water through an indirect water heater. I had J&S quote replacing my boiler (age 19 years) in October 2024 with the intent of hopefully getting a couple of years more out of it before it shit the bed. March of 2025 it started throwing all kinds of errors so i reached out to J&S to replace. I told them I was out of heat and hot water and they were there to help. Price had barely changed from the October quote and they got the job done within a week. These guys are easy to work with and super accommodating. I recommend.

He's honest, friendly, fair and just an all around great guy. Sue Golden2024-12-04Trustindex verifies that the original source of the review is Google. Excellent service! Replaced my 30+ year old furnace. Very happy with this excellent small business. Highly recommend! Jason Watson2024-09-02Trustindex verifies that the original source of the review is Google. We had previously contracted them to replace our existing HVAC system (A frame coil and compressor) over a period of time it became evident that there was an issue within the system. They were always very responsive, and addressed our issues. While it ultimately resulted in a second replacement of our AC system, I can't say enough about their professionalism and skill in finally getting the issues resolved.

They go above and beyond every single time. They have done residential work for both me and my daughter as well as commercial work at my place of business. Had an emergency last night, called them first thing and even tho they obviously had a job for today, Stu returned call immediately and came out on his way home and fixed what we needed done.
