I scheduled a clean and check for both the furnace and the air conditioner. Robert showed up on time and was very thorough. I am very pleased with One Hour and will definitely continue to use them in the future!

This company has some of the best AC repair techs in the stl region. Many of their air conditioning repair technicians have been with the company for decades. Had Nathan install an ultra high end digital programmable WiFi thermostat for my hvac system and I couldn’t be happier. Give them a call for your next AC service and see the difference they can make with your hvac system.
This was an annual winter check, the technician was polite, professional and knowledgeable. Cleaned and checked my furnace. Replaced my filter, and said that my 24 yo is in good working order. Did not, try to sell me a new system, that alone is worth it's weight in good will, and my business.
