Longmont's Plumbing, Heating & Cooling Team
Mountain Valley Plumbing, Heating & Cooling is a Colorado-based company serving homeowners and businesses across the Front Range, from Longmont, Boulder, and Erie up through Loveland, Fort Collins, Greeley, and Windsor. We’ve been working in these communities since 2007, and in that time we’ve built the one thing that’s hard to fake in this trade: a reputation for showing up, pricing honestly, and doing the job right the first time.
We handle plumbing, heating, and cooling under one roof, so when a problem in one system turns into a problem in another, you’ve still got one team and one number to call.
Serving Colorado since 2007
What started as a local plumbing operation has grown into a full multi-trade company running 13 trucks and 13 technicians across the northern Front Range. That scale matters when you call: it means we can usually get a qualified tech to your door quickly, whether you’re in Boulder County or up near Estes Park.
Our technicians install and service the full range of home systems, furnaces, boilers, AC, heat pumps, water heaters (including tankless), sewers, drains, and more. For both residential and commercial clients.
Why homeowners across the Front Range choose us
One team for plumbing, heating, and cooling
Most home problems don’t stay in one lane. A failing water heater becomes a flooring problem; an aging furnace becomes a comfort and safety problem. Because we run all three trades in-house, you’re not juggling separate contractors, and you’re not paying a second service fee when one issue uncovers another.
Flat-rate pricing, quoted up front
We price by the job, not by the hour. You see the number before we start, so there’s no meter running and no surprise on the invoice. [This is the honest answer to the “too many price shoppers” frustration, it pre-qualifies leads who value transparency over the lowest hourly rate.
Background-checked, professional technicians
Every technician is screened before they’re hired and shows up in uniform, on time, and ready to explain what they’re doing. We treat your home like it’s ours.
Local crews who know Colorado homes
Our techs live and work along the Front Range. We know the boiler-heavy older housing stock, the cold-climate heating demands, the well-water and hard-water quirks, and the seasonal swings that put real stress on local systems. That context shows up in better diagnoses.
Where we work
We serve residential and commercial customers across communities along the Front Range, including Longmont, Boulder, Loveland, Fort Collins, Greeley, Erie, Windsor, Estes Park, and the north Denver metro. See our full service areas list, or explore what we do:
