A little unprofessional
Very helpful but did leave the breaker box open, as well as forgot to flip the breaker for the AC unit to come back on, and then walked me through the steps of how to do so over the phone, being that they had already left. A little unprofessional in my opinion, but other than that, great job.

Millers A/C Is Always Outstanding
Have been living in Arcadia for 6 years now, and once I found Millers A/C for repairs, service, and installation, I have not used any other company. Thanksgiving Day, Matt Gray was on call, and they sent him my way for a repair. Thankfully it was nothing major, and he was able to get back home at a good time. He showed up with a smile, was polite, and got right to work and fixed the problem. Not only did he fix the problem, but he double-checked everything to make sure it was all running correctly before he left. Matt was great, and Millers A/C is always outstanding. Thank you!

Frequently Asked Questions
What size AC unit do I need?
The size of the AC unit you need depends on your home's square footage, insulation, number of windows, and local climate. A professional load calculation can determine the right size, ensuring optimal cooling efficiency and comfort.
How long does an AC unit last?
AC units typically last 10 to 15 years with proper maintenance. Longevity depends on usage, climate, and how well the unit is maintained. Regular servicing can often extend the life of your system.
How often should my AC be serviced?
It's recommended to service your air conditioner at least once a year. Regular maintenance ensures your system runs efficiently, extends its lifespan, and can help prevent costly breakdowns. Typically, the best time for an AC tune-up is in the spring before the cooling season begins.
What are signs my AC needs repair?
Common signs include reduced airflow, unusual noises, water leaks, and uneven cooling. Additionally, if your energy bills are higher than usual or there's a strange odor coming from your unit, it's time to call for a professional inspection.
