Replace My HVAC Track

Use home size, replacement cost, AC vs heat pump tradeoffs, ductwork, repair signals, and energy savings to structure an HVAC decision.

Plain English

I need an AC or heat plan. What do I do in order?

Check symptoms, price replacement, compare repair vs replace, look at ducts, and ask quote questions.

Start here: Start with diagnosis if the system is not working today.

What this helps you do

Estimate replacement scope, efficiency tradeoffs, and repair-vs-replace logic before taking HVAC bids.

How long it takes

12-20 minutes

8 guided steps with progress saved on this device.

What you will get at the end

Estimate

Replacement range, likely equipment path, ductwork exposure, and energy savings payback frame.

Checklist

  • home size
  • current system age
  • observed symptoms
  • recent service or thermostat changes
  • test readings
  • duct condition
  • equipment path
  • rebate notes

Your HVAC Plan Scenario

Enter one working estimate, then stress it with low/high ranges, contingency, cash on hand, and monthly capacity. Use the step links below to replace guesses with calculator results as you move through the track.

Range
$10,200 - $15,000
Conservative target
$16,800
Future cash
$9,400
Shortfall
$7,400

Required monthly capacity for the conservative target: $2,133.

Your HVAC Plan

The final result page collects the estimates, risk flags, questions, checklist, and next calculators.

Risk flags

  • undersized or oversized system
  • ductwork excluded from quote
  • unclear warranty labor term
  • efficiency upgrade without payback
  • replacement quote without symptom-to-measurement proof

Next questions

  • Was a load calculation performed?
  • Are ducts included?
  • What rebates apply?
  • What is the backup heat plan?
  • Which cheaper causes were ruled out before replacement was quoted?

Recommended next calculators

Common mistakes

  • buying tonnage by square footage alone
  • leaving ducts out of the decision
  • treating rebate value as guaranteed

Methodology

Each Track packages single-intent calculator pages into a guided decision path. The calculators remain in their vertical hubs; the Track links them together and saves progress locally on this device.

  • Load-estimate guardrails
  • Cost-range comparison
  • Repair threshold framing
  • Energy payback assumptions
