    These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs.

    They had the best price by quite a bit, and the service was outstanding

    4.5 Amy M. Denver, CO

    They were very thorough, knowledgeable, and efficient. Unfortunately, they did send out a tech to repair my furnace when I requested an estimate for furnace replacement and then charged me $90 for their mistaken service visit. I did call to let them know they made a mistake but no offer of a refund was given. Otherwise, I would have given them 5 stars.

    Quick, polite and good price.

    2.5 Sylvia M. Broomfield, CO

    They were thorough in their bid info and services offered. However their bid was $5K over others. You pay for all their warranties.

    3.0 Kala K. Littleton, CO

    I paid in full but the job has not been completed yet. I am still waiting for them to contact me about coming back to finish the drywall they cut into and they have not returned my messages.

    5.0 Al O. Aurora, CO

    Very prompt and efficient.

    5.0 Ricardo P. Aurora, CO

    It took them a little longer to repair my furnace then anticipated. But they fix the issue with it at a fair price
