Emergency Service
The semi-arid continental climate in Denver 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.
"I really liked that they took the time to answer my questions. The tech found out my thermostat was acting up, and now my home in Southlands is the perfect temperature. Nice to have a reliable HVAC company nearby."

What Denver Homeowners Ask About HVAC Contractor
Should I repair or replace my HVAC system in Denver?
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. AllStar Heating and Air Conditioning provides honest assessments for Denver homeowners — we won't push replacement when a $200 repair solves the problem.
What HVAC brands does AllStar Heating and Air Conditioning install in Denver?
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 Denver home.
How long does a new HVAC installation take in Denver?
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. AllStar Heating and Air Conditioning schedules installations to minimize disruption and always ensures your home has heat or cooling by the end of each workday.
