Is it the AC, or something simpler?

Before you price a replacement, rule out the cheap fixes. In our experience these cause most "air conditioner trouble" calls in Brighton:

Call now, don't wait: burning smell from the air handler, repeated breaker trips, or refrigerant hissing from the line set. Those are same-day problems.

Repair or replace? The honest fork

Repair it

AC is under 10 years old, the repair is under ~$600 (capacitor, contactor, drain line), and it still cools evenly. Repair is the smart money.

Replace it

12–15+ years old, uses R-22 refrigerant, needs a compressor, or you've repaired it twice in three summers. At that point you're renting cool air.

Rule of thumb we stand behind: if the repair costs more than about a third of a new system and the AC is past 10 years — or runs on R-22 — replacement usually wins.

What air conditioner replacement costs in Brighton (2026)

Typical installed range, Denver metro
$3,500 – $7,500
Based on 2026 Denver-metro installed quotes for 1.5–5 ton central AC systems, standard to high-efficiency.

Brighton's newer subdivisions usually have straightforward condenser swaps, but the older homes near downtown can surprise you — undersized ductwork and aging electrical are the two things that move an AC quote.

What moves you up or down inside that range:

Field note

Brighton's AC replacements split by era. Older in-town homes often cool with units that were added years after the house was built — sometimes on ductwork designed for heat only, which shows up as weak airflow upstairs on 95° days. In the newer subdivisions, first-generation builder ACs are now 15–20 years old and losing compressors. One Brighton reality: plenty of homes here have big west-facing glass and little shade. A load calculation that accounts for that beats a like-for-like tonnage swap every time.

What happens when you call

  1. We answer and listen. You tell us the symptoms, the equipment's age, and your address. We confirm a licensed installer serves Brighton.
  2. A licensed local tech arrives. They diagnose, give you repair and replacement options in writing, and answer questions on the spot.
  3. You contract directly with the installer. The estimate, the work, and the warranty are between you and the licensed company doing the work — not with this guide.
  4. The installer warranties the work. Equipment warranty from the manufacturer, labor warranty from the installer, both in writing.

How this site works: Mile High HVAC Guide is an independent publisher. We don't install HVAC equipment. When you request help, we connect you with a licensed local contractor and may receive a referral fee from them. It never changes what you pay.

Questions Brighton homeowners actually ask

My AC still uses R-22 refrigerant — what now?

R-22 was phased out and is brutally expensive to recharge. Topping off a leaking R-22 system is throwing money away; replacement with a modern R-410A or R-454B system is usually the right call.

Should I replace the furnace too?

If the furnace is 12+ years old, a matched system costs less than doing the AC now and the furnace in two years — and you get the full rated efficiency. If the furnace is young and healthy, leave it.

Do I need a permit for this in Brighton?

Yes — the City of Brighton requires a mechanical permit and inspection for furnace and AC replacements. Any installer who suggests skipping it is one to avoid.

Our Brighton home was built in the 1970s — does that change the quote?

Often. Older homes here commonly need ductwork repairs, venting updates, or electrical work alongside the equipment — that's the main reason quotes vary. A thorough in-home estimate catches it; a phone quote won't.
