Roger was the 1st person who came out to walk through and do a thorough inspection of our home in regards to installing a Space Pac high-velocity AC unit in our 105 yr old home. He came back two more times after we received the quote, to go over specifics in regards to the installation and placement of the equipment. Jamien & Nick were seasoned, experienced professional installers. They answered all of our questions, arrived on time each day and did a professional job.

Mark came out on the last day to set put the panel and he explained the operations of the new unit to us. We were well taken care of by all involved and my husband and I would recommend Doornbos Heating & A/C to anyone looking for quality products and professional service. Well done gentlemen!

My furnace started to run loud on a Sat night. I searched for a local HVAC place and came to the Doornbos site. I filled out the info form online and first thing Monday morning I got a call from Joyce. She was very nice and was able to get a tech out before noon. Kyle was great! He diagnosed the issue quickly, was able to fix at a very reasonable price, and let me know that the rest seemed to be in fine shape.

I was please with the interaction from start to finished and have signed up for annual maintenance with Doornbos for my Furnace/AC. Based on the customer service and price I definitely recommend Doornbos.

The company was trying to charge me 1500$ for a part that cost 200$ and a fee of 239$ to come and check the problem. Bringing me to a total of 1800$ for visit, parts and labor. The person that came said if I signed up for the yearly maintenance they will only charge me 900$ For the work they were about to do. This price is a rip off to home owners. I will never again call this company for work!

Contracted for furnace cleaning and maintenance. Their technician, George, is hands down the best professional I have ever dealt with. He found a problem I was unaware of and fixed it at a reasonable price. I can't recommend them and George enough! Service: Heating system maintenance

Doornbos is a really professional business. They installed our new furnace and air conditioner and did a great job. The office staff and all the installers went out of their way to make sure the installation was done in a timely manner. I would highly recommend them for all of their heating and AC services!
