Home owner. Yes, I would recommend Ultimate heating and cooling to other potential customers.
Junior and Ricardo showed up on time. They were pleasant and explained what they would be doing. They had to navigate a tight crawl space and took precautions to protect the new furnace as they lowered it in to the crawl space. I assume the furnace was installed correctly because it works fine and passed inspection.

Ultimate is the best
I've had Ultimate out to two different homes to do complete system replacements. Both times I got proposals from three authorized Carrier dealers and both times Ultimate provided the best sales experience and the best price. Install day was a breeze\- the crew showed up on time, laid down protective plastic and complete the tear out and replacement in one day. After the work was complete, they went over the features of the new system in great details. I couldn't have asked for a better experience.

I'm glad we chose them. Had a couple of companies submit estimates on a heating/cooling system for the house, and they had a better price and equipment they used. Everyone I dealt with was great, from the estimate, the office staff, and the guys who did the install. The techs were very professional, informative, and finished the job faster than anticipated. I've had the system for about a week now, and have been loving every minute of it so far.

They are truly a crew a team of professionals who works togetrh seamlessly. They frequently utilize technology to keep me posted (calls/texts and emails). They are like an army of productive ants when it came time to do the install. We are looking forward to cocooning inside in our new AC, when the summer heat hits.

A dealer you can trust
I have worked with Ultimate for the past decade and they have always been reliable, fair and easy to work with. While this was a new installation, I also appreciate their preventive maintenance program which allows me to stay informed each year on the condition of my HVAC equipment and plan for future needs. Would definitely recommend them.

Excellent Customer Experience
Ultimate Heating \& Cooling has superb knowledge of HVAC systems and has excellent skills, expertise and customer service skills, which they demonstrated in replacing my old HVAC system that had two furnaces and outdoor cooling system components. The upstairs furnace was in the attic, which was a difficult area to do the installation work. All of the work done by this dealer was excellent, including the post installation communications with me and their cleanup of the work areas.

After another company that was through a home improvement store said we were "too far" and no installers were near us, they canceled. I had a customer who was wearing his work shirt and we happened to be talking about me needing an a/c unit installed and the rest is history.

5 Star Experience
The team at Ultimate Heating and Cooling were very professional and understand to our situation. Our home furnace had some bigger issue than had previously been fixed by another HVAC contractor. We were referred to Ultimate H\&C by a friend and reached out to them right away. They inspected the problems and gave us some options on repairs or replacement. We decided to replace the 15year old furnace in lieu of fixing it again. Their response to get a replacement installed was really quick and mindful of our needs as there was going to be a change in the weather and a large temp drop. We highly recommend to anyone needing HVAC or A/C repairs or replacement.

Kyle, Kevin and one other nice young man came and installed our new Carrier Infinity Furnace in less than one day! Kyle took special time and effort to explain the system to us, ensuring that we understood the fancy thermostat and helping us set it up on wi\-fi, including on our smart phone!! Ultimate heating and cooling are the best! Kyle submitted a proposal of three different furnaces which we could choose from, and took extra time to explain the differences between them. And Ultimate also helped us finance the cost through Wells Fargo. Thanks, Ultimate!!
