Three core services. Done the right way.

Air Quality

Ventilation & Indoor Air Quality

If your house "just feels stuffy," or your allergies are worse indoors than out, the answer is usually airflow — not the A/C unit. This is the side of HVAC most people skip.

  • Whole-home duct cleaning
  • Duct sealing & insulation
  • Fresh-air intake & ERV install
  • Whole-home dehumidifier
  • HEPA & media filter upgrades

Light Commercial

Small offices, restaurants, and shops.

We don’t chase big-box rooftop contracts, but if you run a small business in Katy or Greater Houston — dental practice, café, retail floor, dance studio — we can take care of your rooftop unit, package unit, or split system. Same family, same number, after the install too.

  • Rooftop unit (RTU) repair & install
  • Package units — gas/electric & heat-pump
  • Light commercial split systems
  • Restaurant exhaust & make-up air
  • 48-hour quote turnaround on new installs
  • Annual maintenance contracts
  • After-hours service available
  • One number for the life of the system

Tune-ups & Service Plans

Twice-a-year tune-ups extend system life by 5–7 years and stop most "summer breakdowns" before they start. We keep it simple — one flat plan, two visits, no contract gotchas.

  • Fall heating tune-up (Sept–Oct)
  • Filter replacements included
  • Coil cleaning & drain flush
  • Refrigerant level check
  • Electrical & capacitor test
  • Priority scheduling for members
  • 10% off any repairs needed
