LGS HVAC Inc. installs, maintains, and repairs heating, ventilation, and air conditioning systems for homes and small businesses across Katy and Greater Houston. Honest quotes, clean work, no upsell theatre.
We keep our scope tight on purpose. Heating, air conditioning, and ventilation — installed, repaired, and tuned by technicians who actually live in the neighborhoods they serve.
New system installs, replacements, refrigerant top-ups, capacitor & compressor repair, plus seasonal tune-ups so it actually keeps up with August.
Cooling services
Furnace, heat-pump, and ductless mini-split installs sized to your home — no oversold tonnage. Repairs and pilot/ignitor service for existing units.
Heating services
Duct cleaning, filter upgrades, fresh-air intakes, dehumidifiers, and HEPA add-ons. The fix to "the house just feels stuffy."
Air quality servicesNo 90-minute "diagnostic fees," no surprise upsells when the tech's already in the attic. Here's what we do differently.
Two-hour windows, not "between 8 and 5." We text 30 minutes out so you don't lose your morning waiting around.
You get the price before we touch anything. If we hit a surprise mid-job, we stop and call — the number on the quote is the number on the invoice.
We do a Manual J load calc instead of "what was here before." Right size = lower bills, longer system life, fewer humidity issues.
Same owners. Same lead techs. The crew that installs your system is the crew that comes back for the tune-up.
