AfterHVAC Company in Leon Valley, TX
Dalton Heating & Air is the HVAC company Leon Valley homeowners call when a system fails in July or a furnace quits during a January cold snap. Our crews work on the specific housing stock that fills Leon Valley: homes from the late 1960s through the early 2000s, many with original ductwork, undersized breaker panels, and heat pumps that are reaching the end of their service life. Every job starts with a written price before any work begins, and every repair is guaranteed in writing for a full year. If you need AC repair, heat pump installation, or furnace repair in Leon Valley, call (361) 306-9515 and you’ll talk to a live person, not a voicemail queue.
Why Leon Valley Homes Are Different
Leon Valley sits directly on the Balcones Escarpment, and that position changes how HVAC systems perform. The limestone shelf under the city holds heat long after sundown, which means air conditioners in Leon Valley run harder during summer nights than systems in flatter parts of the San Antonio metro. Homes along Bandera Road and Huebner Road tend to be older, mid-century construction with less attic insulation than newer subdivisions, so the cooling load is higher than square footage would suggest. We also see a lot of second-generation heat pumps that were installed in the 1980s and 1990s and are now being replaced with variable-speed units sized for the original envelope.
Most Leon Valley residential work happens in single-story homes on quarter-acre to half-acre lots, and access is generally straightforward. What changes from house to house is the condition of the ductwork. Attics in this part of Texas get hot enough that poorly sealed ducts leak a measurable percentage of conditioned air before it reaches the registers. When we diagnose a system in Leon Valley, we check duct integrity as part of the call, because a lot of “AC problems” here are actually duct problems.
Our Main Leon Valley Services
Most Leon Valley homeowners reach out for one of three jobs: a system that stopped cooling, a heat pump that needs full replacement, or a furnace that will not fire. Each service has its own detailed Leon Valley page below.
AC Repair in Leon Valley
When an air conditioner in Leon Valley stops holding temperature in August, the cause is usually one of three things: a capacitor that has failed, a refrigerant leak at a braze joint, or a contactor welded shut from years of cycling on limestone-heated air. We diagnose the issue, quote the repair in writing before we touch anything, and carry common capacitors, contactors, motors, and control boards on the truck so most repairs are done in one visit. Full details, including typical repair windows and what we check on every call, are on our AC Repair in Leon Valley page.
Heat Pump Installation in Leon Valley
Heat pumps are the right call for most Leon Valley homes because winters are short and mild, and a heat pump does double duty without needing a separate furnace. The sizing matters: an undersized unit will struggle against the escarpment heat, and an oversized one will short-cycle and never dehumidify properly. We run a load calculation on every install, quote the equipment and labor in writing, and schedule a set install date. We install Rheem, Goodman, York, and Daikin equipment, depending on what fits the home and the budget. See Heat Pump Installation in Leon Valley for equipment options and the full process.
Furnace Repair in Leon Valley
Furnace work in Leon Valley is mostly confined to a cold stretch between December and February, and the most common failures are ignition systems, draft inducer motors, and limit switches that trip because the filter has been ignored. When a furnace will not light, we test the igniter, the gas valve, and the safety circuit before quoting the repair, because a furnace that “just needs a new igniter” often has a failed limit behind it. The repair is guaranteed in writing for a full year. Read more on our Furnace Repair in Leon Valley page.
