HVAC Company in Marion, TX
Dalton Heating & Air handles HVAC work across Marion, TX with written pricing before any job starts and a full-year guarantee on every repair. Marion’s mix of older ranch-style homes, newer builds along the I-10 corridor, and rural acreage properties means no two systems age the same way. That’s why we stock parts for nine major brands and send background-checked, factory-trained technicians who know what Marion’s heat and humidity do to a condenser coil. If your system is down or running rough, call (361) 306-9515 and a live person answers.
Why Marion Homes Are Different
Marion sits in Guadalupe County where summer temperatures routinely push past 100 degrees, and the humidity makes an undersized or struggling AC impossible to ignore. Housing here spans three distinct generations: 1970s and 1980s ranch homes with original ductwork, 1990s and 2000s brick builds with builder-grade equipment now hitting end of life, and newer construction on larger lots east and south of town. Each presents different challenges. Older homes often have duct leakage that starves bedrooms of airflow no matter how hard the system runs. Mid-age homes are where we see the most compressor and evaporator coil failures, because original equipment is simply worn out. Newer homes tend to have higher-efficiency systems that need precise refrigerant charges – a small error there kills performance. Marion’s hard water also shortens the life of evaporator coils and condensate lines, so we check for scale buildup on every call.
Our Main Marion Services
The three services Marion homeowners call us for most are AC repair during the long cooling season, heat pump installation for homes switching to efficient year-round comfort, and furnace repair for the short but real winter stretch.
AC Repair in Marion
When a Marion AC quits in July, the house heats up fast, and a down system in that kind of heat is a health risk for older adults and kids. We diagnose the problem, put the repair price in writing before any work begins, and most repairs are done same-day with parts from our stocked vans. Marion’s hard water and dust from surrounding farmland both punish condenser coils, so we clean and check the whole system rather than just swapping a part and leaving. Marco Benitez and his team will tell you exactly what failed and why. AC Repair in Marion is the page with full pricing and details.

Heat Pump Installation in Marion
Heat pumps make real sense for Marion homes because they cool in summer and heat in winter from a single unit, and today’s cold-climate models handle Guadalupe County’s occasional freezing nights without backup strips. We size the system to the house, check duct condition before quoting, and give you a written fixed price with a set install date. No surprises. Rheem and Bryant heat pumps are common choices we install here, and we handle the thermostat wiring and refrigerant commissioning by the book. Heat Pump Installation in Marion covers costs, sizing, and what the install day looks like.

Furnace Repair in Marion
Marion winters are short but sharp, and a furnace that won’t light on a 28-degree morning is not something to wait out. We repair gas furnaces, check heat exchangers for cracks, and verify carbon monoxide levels on every combustion call – that is a standard part of our process, not an add-on. Most furnace repairs run $150 to $450 depending on the part, and the full range in Marion is $150 to $700 for major components like blower motors or control boards. Every repair is guaranteed in writing for a full year. Furnace Repair in Marion explains common failures and exact repair costs.

| Furnace Repair | $150 – $700 |

What pushes a Marion job toward the top of these ranges is usually accessibility – attic units packed into tight spaces take longer – and the age of the equipment, since older systems sometimes need a second part replaced while we’re in there. Whatever the final number is, you’ll see it in writing before we start, and that price does not move at the door.
