Marvin'S Heating & Air Conditioning

Marvin's Heating & Air Conditioning works out of Hays County, Texas on heating and cooling systems for local homes. The crew takes on the everyday HVAC demands that show up in this part of the state, where summer heat runs hard and winter cold snaps hit without much warning. They handle service calls, repairs, and installs on furnaces and air conditioners without adding extra layers of sales talk or delays. Homeowners in the county reach out when units break down or need routine attention, and the company stays focused on getting equipment back online using the setups already in place.

They show up for quick AC fixes, such as the job where David and Dylan got a unit running again in less than an hour after the homeowner spent weeks stuck with a warranty company. Furnace replacements come up too, though one case left ductwork connections messy and trash scattered at a rental property. Steve Keithley notes they answer calls and update on arrival times when schedules slip. Gerry Bryant highlights straight diagnoses that skip the fear tactics and upsells common elsewhere, while Mary Beth Schaefer points to fast scheduling and effective results on repairs that had dragged on. The work covers both emergency calls and repeat maintenance across different home setups in the county.

Customers keep coming back because the pricing stays reasonable and the response times beat what they see from other crews. Technicians like David and Dylan earn credit for efficient fixes that actually hold, along with clear communication about what needs doing. Speed and quality show up in most accounts, even if a handful of jobs leave loose ends on cleanup or fit. The record reflects steady performance across the board rather than perfect marks on every visit. DIRT Score 4.36 from 25 reviews on Finds.

“We had these guys come to our rental property. I rarely leave negative reviews, but these guys really earned it. Their work was extremely sloppy; they left all their trash behind and demonstrated an apparent inability to properly fit the new furnace into the pre-existing ductwork. They left significant gaps between the furnace and the air ducts, allowing heat to escape into the attic. This will undoubtedly impact the utility bills. I am surprised by all the five-star reviews, as our experience was far from satisfactory. We mentioned the problems, and they came out a second time, with little change in work ethic, completed work, or trash picked up. I’ve heard from older clients and residents in San Marcos that Marvin, the original owner of this business, was very skilled at his job. It seems that things have changed over time, because in our experience, that is no longer the case.”

“After years of frustrating HVAC service calls sadly lacking in integrity with misleading diagnoses, poor knowledge, sloppy work, and fear mongering sales pitches, it is so uplifting to report on a HVAC company that has restored my belief in the existence of Integrity… I have been using Marvin’s Heating and Air Conditioning Co for the past three years and have experienced a company that serves the industry with strong work ethics, knowledge, and effective customer communication. David Harrell, the owner, has provided the routine annual maintenance and service calls on a timely basis. When my AC went out one summer in August heat, he was here and had the part replaced in a matter of several hours for a very reasonable cost and clear explanation. When the time came for me to consider replacement of my HVAC system, David presented me with multiple options, including the choice of delaying replacement for a while longer. He educated me on different systems (without high pressure sales or fear mongering pitches) and reassured me he was available to answer any questions I had as I researched my options. True to his word, he answered numerous emails/questions with knowledge and patience. And for once, I felt peaceful and confident in my decision to replace my HVAC system at this time, and peaceful and confident in this HVAC company to service and maintain. Thank you, David, for providing a smooth and seamless process in replacement of my HVAC system. The integrity you demonstrate from start to finish does not go unnoticed.”

“I have used Marvin's A/C for several years now. I have found this company to be a reliable A/C company with fair pricing. I have also been impressed with their responsiveness in returning phone calls or contacting me when they are delayed in arriving at my home. In the past I have had A/C service people that would say they are going show up and then do not show up or do not let me know they are going t arrive late. I really appreciate the service that Marvin's A/C has provided and I highly recommend them for A/C Service and Repair.”

“David and Dylan were great. They fixed my AC in probably less than an hour—after I spent a month battling with my home warranty company to get it repaired to no avail. The price was fair, and the service was efficient and effective. I was able to get an appointment quickly, and everyone I interacted with was pleasant and helpful. I’d highly recommend.”

“Fast, Friendly, Professional service. David Harrell and Marvin's did an outstanding job for us, including excellent follow-up concerning a company rebate. I very strongly recommend Marvin's Heating and Air Conditioning.”
