I can't say enough good things about Miller's!! They were very efficient and explained all of our options. We had our whole unit replaced since it was installed in the 90's. They recommended the perfect system for our square footage and had it installed in less then 8 hours!! They were very friendly and clean. If you need repairs or replacement of your heating and air, I recommend Miller's 100%!!

Miller's came out to quote replacing our 25+ year old furnace and A/C unit. DJ carefully assessed our needs, provided a detailed estimate, and helped us choose the best replacement unit for our home. The installation process was seamless, and the technicians worked efficiently to ensure everything was set up perfectly. DJ stayed in constant communication throughout the installation and permit approval process. I highly recommend them for anyone in need of HVAC services. Thank you for your excellent work and dedication to customer satisfaction!
