Customer Testimonials

Laura G.
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!

Decided it was time to replace my HVAC system that Miller's installed 40 years ago. Again Miller's had the best quote and were able to install right away. Technicians Adrian and Sergio installed the new system in one day and even worked through their lunch! The workmanship looks top notch.

I love Miller’s. I manage property and they are always prompt and considerate. My tenants love them. I personally just had them replace my heater and air conditioner. Again, they were prompt and efficient. Got the job done and you couldn’t even tell they were there.
I highly recommend them!

I had a great experience from this local company. From my first meeting with Mike to the final day with the install crew, it just went almost TOO smoothly.
Replacing a heat and air conditioning system is a major investment and there are lots of options to consider. Mike was great at explaining how things would be installed and exactly what I would be getting. He's a patient guy. The install crew, Dan, Sean and Cameron were efficient, left the work areas clean and picked up, and took the time to explain the operation and maintenance tips.
Local company, great crew, happy customer.
