David has been trained and certified in all areas of HVAC, including brands such as Trane, Carrier, and Lennox to name a few. David holds all licenses and certifications required, including all state HVAC licenses, required to operate in the state of Texas. Qualified and experienced in all brands of equipment, we take care of any heating and/or air conditioning issues. A/C Works is licensed and insured, carrying far above the minimum requirements necessary and required by law. Our goal is to keep our work environment as clean and as safe as possible, taking every precaution to make sure your home is left better than it was when we arrived. Our customers are our biggest fans, complimenting our work ethics and practices daily. Payment for services is expected at the time of delivery unless prior arrangements have been made with the finance office. We accept cash, checks, Visa, Mastercard, Discover and American Express. We also provide financing through Wells Fargo Retail Financing and GreenSky as a convenience to our customers. We're a small company, but you always know who is answering the phone when you call, and who is coming to your house when you need us. We are always "On A Mission To Deliver Comfort!™" to you and your family.
"If you want to hear lies and sales pitches, this is the company for you! Ask for Jason cause he is full of them! Jason arrived and within five minutes (before he started trying to diagnose anything) he tells me our AC unit is too small to cover the square footage of our home. I asked him how many square feet our unit can cover and he proceeds to tell me not even 1600 sqft. Our unit is 3.5 tons (which covers 1800 to 2100 sqft). After I educated him on the spot and told him that was not an option I should’ve dismissed him right then and there but being desperate for cool air, I proceeded to let him diagnose my issue. Jason proceeds to tell me my TX valve is indicating a blockage and needs replaced along with the dryer outside. I told him OK and said the parts are covered under warranty. He then tells me “no my warranty is void because somebody marked through my a coil serial number with a permanent marker”. (Our home is new, we’re the only owners of the home, and we’ve never had our AC unit looked at. No way somebody marked through the serial number with a permanent marker unless it was him.) I tell him to send me a bid and I pay over $157 for the service call/hour to diagnose. I immediately called another company out who arrived that evening. The diagnosis was the same. However, the other company tells me my parts are covered under warranty. A/C works bid: $1,456.08 (TX value $619 and drier $113) plus labor and refrigerant-which was needed. Had we proceeded with A/C works we would have paid them $1,613.92 total (first call plus repair call). I paid $157.84 to be fed a bunch of crap sales pitches and lies from Jason."
