Horizon Services Plumbing, Heating & Air brings full-service home comfort coverage to Denver and the surrounding metro, operating 24 hours a day with a team that handles everything from boiler replacement to sump pump service. Reachable at (720) 575-1709, the company handles air conditioning repair and installation, furnace repair, boiler installation and repair, heating tune-ups, plumbing and water heaters, and mini-split systems — a range that makes them a single contractor for most home service needs.

The company's installation background includes whole-system replacements that require coordination across multiple trades and equipment types. One reviewer who replaced two furnaces and two A/C condensers immediately after buying a new home described Horizon as their ongoing HVAC provider four years later, with the Trane systems still performing well and the relationship maintained through annual maintenance. Another reviewer whose boiler replacement was handled during a stressful period specifically praised technicians Jonathan and Tom for being communicative and honest about the pricing they could offer — language that suggests a team that treats service calls as relationships rather than transactions.

Technicians Josh and Jason each received named recognition in reviews. Josh was praised for professionalism and thoroughness from the initial call through the end of service. Jason earned recognition for detailed explanations during an annual furnace inspection. A third reviewer described Horizon's team replacing a leaky spray-foam plumbing hack from a prior quick-flip — a job that required diagnosing a non-standard prior installation, communicating clearly about what was found, and fixing it professionally.

Horizon Services operates with online booking available through horizonservicesdenver.com and runs periodic specials for customers who check the site before scheduling. For Denver homeowners dealing with a multi-system home or looking for a company capable of both HVAC and plumbing under one roof, Horizon's 24-hour availability and documented track record across installation types makes them worth contacting.
