Family-owned since 2009. Built on referrals.
Mike Reyes started Apex HVAC in 2009 after watching his dad get hit with a $1,200 bill for a $90 part and two hours of labor. He believed Denver homeowners deserved a heating and cooling company that quoted honestly and showed up when it said it would.
Fifteen years and 500+ jobs later, that's still the standard. We've grown from a one-truck operation to a full team of NATE-certified technicians, but every job still gets quoted before we touch anything — no exceptions.
We believe a fair quote and a tech who actually explains what's wrong will earn a customer for life faster than any sales pitch. That's why most of our work still comes from referrals, not ads.
The things we won't budge on
No surprises on the invoice
We quote before we touch anything. If the scope changes once we're inside the unit, we call you first — you approve it before we keep going.
A 2-hour window means 2 hours
We don't give a 4-hour guess and hope. You get a real arrival window and a text 30 minutes out, every time — emergency or not.
We tell you what we actually found
If a repair will hold for another season, we say so. We've turned down upsells more than once — it's why customers keep calling us back.
What to expect when you call us
Free inspection & written estimate
We come out, diagnose the issue, and give you a written number on the spot — most visits same-day or next-day.
You review and approve — no pressure
No same-visit close tactics. Take the estimate, ask questions, decide when you're ready. We'll still be here.
We do the work — clean site, no surprises
Drop cloths, shoe covers, and a tech who explains what's happening as it happens. If something changes, you hear it from us first.
Final walkthrough + guarantee documentation
We walk the system with you, confirm it's running right, and leave you with the paperwork on your guarantee — comfort or we come back.
