On Time Heat & Air has served the Denver Metro since 2013 with a 5.0 Google rating, NATE Certified technicians, and active licenses in 8 Colorado counties. Here's what sets us apart.
Not all HVAC companies are equal. Here's what separates the best from the rest in the Denver market — and how On Time Heat & Air stacks up:
Only 10-15% of HVAC technicians hold NATE certification — the industry's highest standard. All On Time technicians are NATE certified. Many Denver HVAC companies use uncertified helpers for service calls. Ask before you book.
Colorado doesn't have a state HVAC license — it's county-by-county. Many companies operate with licenses in only 1-2 counties. On Time Heat & Air holds active licenses in 8 counties: Adams, Arapahoe, Aurora, Broomfield, Denver, Douglas, Jefferson, and Commerce City.
HVAC at 5,000+ feet is different. Gas pressure, refrigerant charge, and airflow all change with altitude. A company that learned HVAC at sea level will make mistakes in Denver. We've been calibrating for the Front Range since 2013.
The best HVAC companies tell you the price before they start. On Time provides upfront pricing on every job. No hidden fees, no "well, now that we opened it up..." surprises. See our pricing page for current rates.
5.0 stars across 70+ Google reviews — and every one is from a real Denver Metro homeowner. No paid reviews, no fake accounts. Read them on our reviews page or directly on Google.
On Time Heat & Air is locally owned and operated from Brighton, CO — not a franchise, not a call center. Owner Hamid is still on job sites and still answers the phone. Learn more on our About page.
