Mountain Valley Plumbing and Heating

Mountain Valley Plumbing and Heating maintains a 4.9-star average across 817 verified client reviews, positioning them among the highest-rated heating and cooling specialists serving Longmont, Boulder, Denver, and surrounding northern Colorado communities. This full-scale operation handles residential plumbing installations alongside heating and cooling systems, offering everything from routine AC maintenance to complex furnace replacements and tankless water heater setups. Their physical location at 210 Collyer St. anchors a service network covering Fort Collins, Greeley, and Estes Park.

The company distinguishes itself through comprehensive indoor air quality services, including dedicated air duct cleaning for heating, cooling, and ventilation systems. They install ductless mini-split configurations ideal for home additions and zone-controlled comfort solutions, while also maintaining expertise in swamp cooler systems popular throughout Colorado's semi-arid climate. Backflow prevention testing and certified backflow device installation represent an often-overlooked specialty that protects residential water supplies.

Customer narratives reveal consistent responsiveness and technical thoroughness. When Gloria Owusu's furnace failed during cold weather, technician DJ arrived the same afternoon, performed a detailed diagnostic, and facilitated next-day installation of both a new furnace and tankless water heater by crew members Fernando and Franco. Kari Owens experienced a weekend toilet leak requiring Monday intervention, and six months prior when Mountain Valley voluntarily corrected another contractor's dangerous furnace installation error at no charge, a decision the reviewer called unforgettable.
