AfterHVAC Company in Tomball, TX
HVAC work in Tomball comes down to one thing: most of the housing stock was built for a Houston climate, but the newer subdivisions on the northwest side sit on clay soil that shifts with every drought-and-downpour cycle. That movement stresses ductwork, pad-mounted condensers, and drain lines in ways a crew that only works inside the Loop never sees. Dalton Heating & Air sends background-checked, factory-trained technicians to Tomball every week for AC repair, heat pump installation, and furnace repair. The price is in writing before any work starts, and every repair carries a full-year written guarantee. Call (361) 306-9515 and a live person answers, day or night.
Why Tomball Homes Are Different
Tomball splits into two housing eras. The original grid around Main Street and the railroad holds homes from the 1950s through the 1980s, many with pier-and-beam foundations, undersized return ducts, and electrical panels that predate modern AC loads. West and northwest of downtown, the subdivisions off FM 2920 and SH 249 – neighborhoods like Lakewood Grove, Wildwood at Northpointe, and the acreage communities around Hufsmith-Kohrville – were built fast in the 2000s and 2010s. Those houses have tighter envelopes but longer duct runs, and the expansive clay under Tomball’s northwest side heaves enough during summer dry spells that we regularly find separated duct joints and condensers that have settled out of level.
The other variable is humidity. Tomball sits far enough from the Gulf that it avoids the worst coastal salt, but summer dew points stay in the mid-70s. An oversized AC will short-cycle and never pull moisture out of the air, which is why we check static pressure and duct sizing on every repair call rather than just swapping the failed part. Heat pumps, which are becoming the standard for Tomball replacements, have to be sized and charged correctly to handle both the August load and the occasional January cold snap without auxiliary heat running all month.
Our Main Tomball Services
Three services cover the vast majority of what Tomball homeowners call us for: repairing an AC that quit, replacing a heat pump that has reached the end of its run, and fixing a furnace when the winter front blows through. Each one has its own Tomball page with pricing and the full detail.
AC Repair in Tomball
When a Tomball AC fails in July, the problem is usually one of three things: a failed dual-run capacitor, a refrigerant leak at a brazed joint, or a condensate drain clogged with the algae that thrives in our humidity. The fix is straightforward, but diagnosing it wrong is expensive, which is why every call starts with written pricing before any work begins. Tomball homes with attic-mounted air handlers need a technician who will actually inspect the secondary drain pan and float switch, not just clear the line and leave. AC Repair in Tomball covers the full repair process, what it costs, and how fast we can get there.
Heat Pump Installation in Tomball
Tomball’s mild winters and long cooling season make a heat pump the most efficient choice for most replacement jobs. The catch is that installation quality matters more than the brand name on the cabinet. A heat pump that is overcharged by half a pound or connected to undersized ductwork will run constantly in August and still leave the far bedrooms warm. We run a full load calculation on every Tomball installation, replace the disconnect and whip, and commission the system against the manufacturer’s startup sheet. Heat Pump Installation in Tomball walks through sizing, rebates, and what a typical install day looks like.
Furnace Repair in Tomball
Furnace calls in Tomball cluster in December and January, when the first real cold front hits and a system that has sat idle since March refuses to fire. The most common culprits are failed ignitors, dirty flame sensors, and cracked heat exchangers on units that are past their service life. A cracked heat exchanger is a carbon monoxide risk, which is why we test combustion on every furnace repair rather than just resetting the board and driving off. Furnace Repair in Tomball explains the repair ranges, the safety checks, and the exact terms of the written guarantee.

Brands We Service in Tomball
Our technicians are factory-trained on the major residential brands homeowners actually have in Tomball, including Rheem, Trane, Carrier, Lennox, York, Goodman, Daikin, Bryant, and American Standard. We stock common capacitors, contactors, ignitors, flame sensors, and control boards locally so most repairs don’t wait on a parts run.

Pricing for HVAC Company in Tomball, TX
| Service | Typical range in Tomball |
|---|---|
| AC repair – diagnostic and common fixes | $150 – $650 |
| Furnace repair – ignitor, flame sensor, or control board | $150 – $700 |
| AC installation – full system replacement | $3,500 – $7,500 |
| Tune-up – seasonal maintenance visit | $80 – $200 |
What pushes a Tomball repair toward the top of the range is access: attic-mounted air handlers in August are a harder job than a ground-level condenser in October, and systems on the northwest side often need duct sealing work that a simple part swap does not include. No matter what the job needs, the price is in writing before any work starts, and the guarantee on every repair is a full year, not a 30-day window.
