Top HVAC Companies in Houston
Houston’s climate is a double whammy: long stretches of 90°+ days, dew points parked in the 70s, and sudden storm fronts that swing from steamy to soggy in an afternoon. In peak months, air conditioning can account for 40–60% of a home’s electricity use, and poor ductwork alone can waste 20–30% of cooled air. That’s why the team you choose matters as much as the equipment itself. The top HVAC companies in Houston don’t just swap boxes; they size systems correctly for Gulf Coast humidity, design ductwork that actually delivers the airflow you’re paying for, and commission every install so it performs on day one—not “after it breaks in.”
Since 2023, the South Region (including Texas) minimum efficiency has shifted to SEER2 14.3 for split systems, with updated EER2/HSPF2 ratings too. Great contractors will explain how that translates to real savings, when a heat pump beats a straight-cool + gas furnace, and why humidity control (not just temperature) is what makes a Houston home feel comfortable at 75°F. Expect them to talk static pressure, sensible vs. latent loads, and filtration that tackles oak/pine pollen without choking your blower.
Good HVAC also protects your home. Think overflow shutoff switches on attic air handlers, float switches on secondary drain pans, whole-home surge protection for control boards, and proper refrigerant line-set replacement during change-outs. Add smart thermostats (typical 8–15% savings when used well) and you’ve got comfort that’s efficient, resilient, and easier on the grid when ERCOT is peaking.
Quick Houston HVAC checklist:
- Licensing & insurance: Texas TACLA license; pulls permits and schedules inspections.
- Right-sizing: Written Manual J/S/D (load, duct, and register design) before quoting tonnage.
- Commissioning: Startup report with airflow (350–450 CFM/ton), static pressure, superheat/subcool.
- Ductwork: Test/repair leaks; design for low static; insulate and properly seal with mastic.
- Humidity control: Dehumidification strategy (staged/variable systems or dedicated dehumidifier).
- Efficiency: SEER2/EER2 explained in dollars for your usage; utility rebate guidance if available.
- Protection: Condensate float switches, drain safeties, surge protection, and flood-aware placement.
- IAQ: MERV-13 (or better) filtration with pressure drop considered; fresh-air/ERV options.
- Transparency: Line-item proposals, model numbers, labor/parts warranties (aim for 10-yr parts, 2+-yr labor), and maintenance plan details.
