LongmontLongmont Plumbing, Heating & Air — Flat-Rate Service You Can Trust

JT Plumbing Heating & Air is a family-owned company — we don't cut corners, we don't pad invoices, and we don't recommend work you don't need.

Residential Plumbing & HVAC Services

We provide the full range of residential maintenance, repairs, and installations. Plumbing repairs from leaky faucets to major water line work. Emergency response for burst pipes, sewer backups, and other can't-wait situations. Drain cleaning with professional equipment and camera inspections. Water heater installation, repair, and replacement — both tank and tankless systems. Furnace repair, AC repair, and complete system replacements. Plus HVAC maintenance memberships to keep everything running and save on repairs.

Longmont's Older Homes Need Regular Attention

Some of Longmont's most charming neighborhoods — Twin Peaks, Prospect, the areas near Main Street — have homes with plumbing that's been working for decades. These homes often have galvanized steel or cast iron pipes that corrode over time, original sewer lines with root intrusion, and aging water heaters fighting years of mineral buildup.

If you're in an older Longmont home, proactive maintenance is the difference between a planned repair and a 2 AM emergency. Annual water heater flushes, periodic drain and sewer inspections, and regular HVAC tune-ups keep your systems healthy and your wallet intact. Our membership plans handle all of it on a schedule.
