Emergency Service
The semi-arid continental climate in Longmont presents specific challenges for local properties and residents. With 15-17 inches annually of annual precipitation and temperatures ranging from 15-25°F to 88-95°F, the environment creates conditions that require local expertise to navigate effectively.
"Overall happy with the service, but it did take a couple of tries to get someone out to my home. Once the guy who came out was here, he really knew his stuff. They fixed our old air conditioning unit, and it’s running like new now, but just wish it happened faster."

What Longmont Homeowners Ask About HVAC Contractor
Should I repair or replace my HVAC system in Longmont?
The '5,000 Rule' helps: multiply the system's age by the repair cost. If the result exceeds $5,000, replacement is usually more cost-effective. Other replacement indicators include: the system uses R-22 refrigerant (phased out, expensive), repair costs exceed 50% of a new system, or energy bills have increased 15%+ despite maintenance. SummitAir Heating and Cooling provides honest assessments for Longmont homeowners — we won't push replacement when a $200 repair solves the problem.
What HVAC brands does SummitAir Heating and Cooling install in Longmont?
We install and service all major HVAC brands. Our recommendations are based on reliability data, warranty coverage, parts availability in CO, and value for your budget — not brand partnerships. During your free estimate, we present 2-3 options at different price points so you choose the best fit for your Longmont home.
How long does a new HVAC installation take in Longmont?
A standard residential HVAC replacement takes 1-2 days. If ductwork modifications are needed, add 1-2 additional days. New construction or complete system redesigns may take 3-5 days. SummitAir Heating and Cooling schedules installations to minimize disruption and always ensures your home has heat or cooling by the end of each workday.
