“We needed to replaced our old HVAC system in our church due to age and issues with the old unit. We called a few companies to get an estimate but one hour AC Service seems to be the best of all they came out and gave us an estimate that was right within our budget. They out at the earliest convenience after approve and did the work. Everything turns out great, we now have a new HVAC system installed in our church and we were happy with overall service. We would recommend this company to anyone for services. Thanks again for a job well done. Greater Emmanuel apostolic church.”

“If I could give more than 5 stars I would. To begin Luis is friendly, professional and honest. I previously went with Metro for my HVAC needs and they were constantly trying to upsell me, telling me since my coils were rusted I needed to replace my entire system for $13k. But Luis with one-hour was honest with me he said "no we can just replace the coil, everything else on your system is working". One-hour has made a life long customer out of me.”
