Allen Service

Allen Service has been a fixture in northern Colorado since 1988, operating under contractor license CRC284954 and earning a 4.8-star average across 65,564 verified customer reviews. The company staffs licensed technicians across four trade disciplines, HVAC, plumbing, electrical, and sewer, serving Fort Collins and the broader Denver Metro area from a dispatch center that rings 24 hours a day, 7 days a week. Homeowners in communities from Old Town to Westminster call Allen Service for projects ranging from a single outlet replacement to whole-home heat pump installations.

What distinguishes Allen Service from regional competitors is its breadth of in-house capability. The company handles everything from AeroSeal duct sealing, aerodynamic sealing that targets hidden air leaks in conditioned envelope cavities, to tankless water heater retrofits and car-charging-station rough-ins, all under one roof. The Allen Service Membership Rewards Plan lets repeat customers accrue credit toward future service, and the BOGO promotion currently on the homepage offers a free furnace with qualifying air conditioning installation through May 31, 2026. No other single-contractor operation in Larimer County matches that combination of trade depth and consumer incentive structure.

Customer reviews consistently name technicians who solve problems that stump rivals. Tony, an Allen Service electrician, diagnosed a short-circuit condition and completed a same-day repair that had left another contractor stumped. At a rental unit, Nate, Mathew, and Mason traced a persistent floor leak to a hidden supply-line failure that six previous drain specialists had missed, communicating each diagnostic step to the property owner in real time. Tyler installed a whole-home water filtration system, walking the homeowner through three price-point options before scheduling the install and even incorporating plumbing modifications to address a chronic pressure complaint. Across every reviewed scenario, the common thread is a refusal to pad invoices with unnecessary work, techs propose cheaper, smarter fixes and let the homeowner decide.
