When Longmont temperatures dip, a reliable furnace is what keeps your home comfortable. My Guy Heating and Air helps you plan and complete furnace installation services.

Professional HVAC furnace installation in Longmont starts with an in-home evaluation and accurate load calculation, plus a duct inspection and airflow assessment to identify restrictions or imbalances. From there, we recommend equipment based on data, remove the old unit safely, and install the new system to manufacturer’s requirements and local code.
We also coordinate permitting and inspection steps aligned with Longmont requirements. Before we wrap up, we will complete start-up commissioning and safety checks, including gas connection verification and carbon monoxide testing, then walk you through thermostat settings, filter needs, and what normal operation looks like.
If you are seeing repeated breakdowns, short cycling, uneven heat, or higher utility bills, furnace replacement in Longmont is often more practical than chasing repairs. We evaluate the full system, including venting, duct condition, and safety components, then recommend the most sensible path forward.
If you want flexibility on timing and budget, you can explore our financing options and decide what fits without being pushed into unnecessary add-ons.

How much does furnace installation cost in Longmont, CO?
Pricing depends on the furnace type and efficiency level, your home’s load calculation, ductwork condition, venting requirements, and whether electrical or gas line work is needed. After an in-home assessment, you should receive a clear scope and written estimate.
What size furnace do I need for my home?
The right size comes from a load calculation that accounts for square footage, insulation, windows, ductwork, and local climate. Oversizing can cause short cycling and uneven comfort, while undersizing can struggle on colder nights.

Permits are commonly required for new HVAC installs and many replacements. Working with a licensed contractor helps ensure permitting and inspection requirements are handled correctly.
