Spencer & Crew are amazing! I have so much peace of mind knowing they are keeping tabs on my HVAC. Adore them! Without having a degree in Heating & Cooling from Madison College it’s hard to know who to trust. You can trust Latitude 43.

Had a great experience working with Spencer - he saved the day when our AC unit went out this Summer, and he was prompt, great at communicating ahead of the project, and gave us a fair price. Will definitely be working with Latitude 43 HVAC for our future HVAC needs.

I met the owner, Spencer 3 yrs ago. We were doing a remodel, he came up with solutions to improve the hot water radiators heating, and we added zonal mini-splits for cooling/heat augmentation. He's prompt, fair, does quality work with great communication along the whole process. Small business pride and skill, personal treatment.

I had new ductwork installed in a crawl space under a room that was in addition to my house where no ductwork had been before. Spencer did a great job figuring out the best path for the ductwork and even got a vent cover that matched the wood of my floor. Great work and reasonable price.

We had an ideal experience for our HVAC tune up with Spencer. Knowledgeable and professional and he took the time to explain everything and answer any questions I had. We will undoubtedly use Latitude.43 for all of our future HVAC needs.
