How a heat pump works
A heat pump doesn't create heat — it moves it, using the refrigeration cycle:
• The outdoor coil evaporates refrigerant, absorbing heat from the outside air — yes, even cold air holds heat.
• The compressor squeezes that refrigerant, raising its temperature.
• The indoor coil condenses it, releasing the heat into your home.
• An expansion valve drops the pressure and the cycle repeats.
A reversing valve flips the whole process for summer — the indoor coil becomes the evaporator and the system cools. The same valve runs the defrost cycle: below about 40°F, frost builds on the outdoor coil (normal), so the system briefly reverses, sends hot gas to the outdoor coil, stops the outdoor fan, and melts it off — often with backup heat covering your home meanwhile.
Single-stage vs. inverter: an old-school compressor is on or off, like a light switch. Modern inverter (variable-speed) compressors modulate output like a dimmer — running long, steady, quiet cycles that hold temperature tighter, dehumidify better, and use less energy at part load.
How a gas furnace works
Thermostat calls → burner ignites gas → the heat exchanger (a metal barrier keeping combustion gases away from your household air) gets hot → the blower pushes your home's air across it and into the ducts.
AFUE is the efficiency rating — the percentage of fuel converted to heat over a season. Standard furnaces run about 80% (hot exhaust goes up the flue); condensing furnaces hit 90–98%+ with a second heat exchanger that squeezes heat from the exhaust before venting it through PVC pipe.
Staging (single-stage, two-stage, modulating) is mostly about comfort, not the AFUE number: a modulating furnace can cruise at a fraction of full output instead of blasting on and off, so temperatures stay even and the system runs quieter.
How systems wear out
Nothing here lasts forever. Typical service life: furnaces 15–20 years, central air conditioners around 15, heat pumps and mini-splits 10–20 (running year-round shortens the span). What actually fails:
• Compressors — the costliest failure; the heart of any heat pump or AC.
• Heat exchangers (furnaces) — they can crack with age, letting carbon monoxide into your airstream. Warning signs: the CO alarm sounding, soot around the furnace, a yellow burner flame instead of blue. A cracked heat exchanger can't be safely patched — the exchanger or the furnace gets replaced.
• Capacitors and contactors — small electrical parts, common early failures; a hard-starting system is often the first domino.
• Blower and fan motors, reversing valves (a valve stuck in one mode), coils and refrigerant leaks.
• Efficiency fades long before anything breaks: dirty coils, lost refrigerant charge, leaky ducts, worn compressors, and airflow problems all quietly raise your bills.
Why refrigerants keep getting phased out
R-22 ("Freon"): production and import ended January 1, 2020. Owning and running an R-22 system is still legal, and servicing continues with reclaimed refrigerant — but there's no true drop-in replacement, and supply only shrinks. If your system still runs on R-22, every repair quote should include the replacement conversation.
R-410A: the replacement for R-22 — but with a global-warming potential around 2,088, it was always a bridge. Under the federal AIM Act, HFC refrigerants phase down 85% by 2036. As of January 1, 2025, new residential systems must use refrigerants under 700 GWP: the mildly-flammable A2L class — R-454B (GWP ~466, used by Carrier, Trane, Lennox, Rheem) and R-32 (GWP ~675, used by Daikin and others).
If you own an R-410A system: per the EPA, keep it and repair it for its full useful life — parts remain available. The new-refrigerant rules apply to new systems. (The regulations here are still evolving; I'll tell you what's current when we talk.)
Why a new system often means more than the box
When a 15–20-year-old system dies, homeowners are sometimes surprised the quote includes a new copper lineset, electrical work, and ductwork changes. It's not upselling — the old system was designed for a different world:
• Oil incompatibility. R-22 systems used mineral oil; modern systems use POE oil. The two don't mix — leftover mineral oil degrades the new oil and kills new compressors. Flushing old lines is unreliable, so replacing the lineset is the warranty-safe move.
• Higher pressures. R-410A runs 50–70% higher pressure than R-22. Old copper and components weren't built for it.
• SEER2 standards (2023). Efficiency ratings got tougher and now only apply to factory-matched system combinations — you can't bolt a new high-efficiency condenser onto a 15-year-old coil and get the rated efficiency (or the warranty).
• Airflow. Modern variable-speed equipment needs about 400 CFM per ton of airflow. Ductwork designed for decades-old equipment often chokes it — causing noise, poor comfort, and early breakdowns.
• Electrical. The new unit's nameplate amperage and breaker size often differ from the old one's, and code requires a disconnect within sight of the equipment. Old panels and fuse boxes sometimes force an upgrade — especially switching from gas heat to a heat pump.
That's the honest version: new energy-efficient systems are genuinely better, but they're engineered as a system — and the parts around them have to match.
