AC Installation & Replacement in Aurora, CO

FREE REPLACEMENT QUOTES · COST FACTORS [TBD]

She needs a new air conditioner and furnace to replace her 30-year-old unit — we hear some version of that every week. Here's the honest version: right-sized equipment, the repair-vs-replace math in writing, and a crew that finishes in a day.

Repair or replace

The math we do before we sell you anything

Here's our rule, and we'll put it in writing on your quote: if the repair costs more than a third of a new system and your unit is 12–15+ years old, replacement wins. A 1990s condenser with a dead compressor isn't a repair candidate — it's a donation to your electric bill.

But we are repair-first by default. A 9-year-old system with a bad capacitor gets a capacitor, not a sales pitch. When we recommend replacement, we show you both numbers side by side: repair cost now, expected remaining life, and the efficiency difference. Then you decide. That's it.

Thinking about the furnace too? If both systems are 15+ years old, ask us about a cold-climate heat pump — one system that heats and cools, built for Colorado winters.

What's included

A replacement done right, not just done fast

  • Load calculation (Manual J). We size the system to your house — square footage, insulation, windows, ductwork. Oversized systems short-cycle, waste energy, and leave you clammy.
  • Matched system, not a Frankenstein. Condenser and coil designed to work together, with the efficiency rating we quoted — verified at startup.
  • Ductwork inspection. Half of Aurora's comfort problems are ducts, not equipment. We check static pressure and seal what's leaking before the new system goes in.
  • New line set, pad, disconnect, and thermostat. The small stuff that cheap installs skip — and that fails first.
  • Permits pulled, every time. Aurora requires them; we handle the paperwork and the inspection.
  • Startup commissioning with numbers. Refrigerant charge, airflow, and temperature split measured and recorded — not "feels cold, good enough."
  • Old equipment hauled away. Refrigerant recovered per EPA rules, unit recycled.

Straight answers

AC installation FAQs

How much does AC replacement cost in Aurora?
It depends on system size, efficiency, and ductwork condition — anyone quoting you a flat number over the phone is guessing. We do a free in-home assessment with a load calculation and give you the exact number in writing. Cost factors are listed above; full ranges on /pricing/.
Repair or replace — how do I decide?
Our rule: repair cost over a third of replacement + system age 12–15+ years = replace. We'll show you both numbers and the efficiency difference side by side. If repair is the smarter money, we'll say so.
What size AC does my house need?
Whatever the load calculation says — that's the Manual J, based on your home's size, insulation, windows, and ductwork. Bigger is not better: oversized ACs short-cycle, spike your bills, and leave the house humid.
How long does installation take?
Most straight replacements finish in one day. Ductwork modifications or electrical upgrades can stretch it to two. You have cooling back the same day we start in nearly all cases.
Do you offer financing?
Yes — $0-down options with monthly payments, most approvals in minutes. See /financing/ for the details.
Should I consider a heat pump instead?
If your furnace is aging too, a cold-climate heat pump can replace both systems and handles Colorado winters far better than old heat pumps did. Worth a conversation — see heat pump services.
