Add-ons that may be quoted separately: line-set run longer than 25 ft (+$280-$580), ductwork modifications ($380-$2,400), code-required electrical upgrades ($280-$890), crane for rooftop units ($480-$1,200), and extended labor warranty ($280-$680).
Heating System Costs in Florida
95% of South Florida heating is electric — either a heat pump (the AC reverses) or resistive strip heat as backup. True gas furnaces are rare except in large older homes. Typical costs:
- Heat pump upgrade over AC-only: adds $400–$1,400 to installation
- Strip heat element replacement: $320–$680
- Reversing valve (heat pump): $580–$1,100
- Defrost control board: $290–$520
- Gas furnace tune-up: $189
- Gas furnace install (replacement): $3,800–$6,800 equipment-only; full system $8,400+
Indoor Air Quality Add-Ons
- UV-C coil light: $580-$890 installed — kills mold on evaporator coil, helps allergy sufferers
- Bi-polar ionization (REME Halo): $780-$1,200 — viruses & VOCs throughout home
- Whole-home dehumidifier: $2,400-$4,200 — for homes stuck above 55% RH
- MERV 13-16 media filter cabinet: $680-$1,100 — best for allergies & pets
- Duct cleaning: $380-$780 whole-home (skip if not symptomatic — most duct-cleaning is upsell)
Maintenance Plans — What They Should Cost
- Basic annual tune-up (1 visit): $149-$229
- Two-visit plan (spring + fall): $240-$380
- Premium plan (2 visits + discounts + priority): $480-$720/yr or $40-$62/mo
- Red flag pricing: any plan over $80/month for a single-family home is priced for a commission-based sales team, not for you
Diagnostic & Trip Fees — What’s Normal
- Standard business-hour diagnostic: $39-$99 (applied to repair if you book)
- After-hours (7 PM-11 PM): $89-$149
- Overnight (11 PM-7 AM): $129-$249
- Weekend premium: $0-$79 extra (many contractors charge nothing)
- Holiday premium: typically 1.5× business-hour rate
How to Save Money Without Cutting Corners
- Book off-season. Service and install prices drop 10-25% between November and April. Summer emergency pricing is real.
- Get 2-3 written quotes for system replacement. Never just one. Real contractors welcome the comparison.
- Match the unit to your home. Bigger is not better. Oversized ACs short-cycle, don’t dehumidify, and die younger. Insist on a Manual J load calculation.
- Upgrade ductwork BEFORE replacing the unit. Leaky ducts waste 25-40% of your AC’s output regardless of efficiency.
- Skip the extended labor warranties from dealer-financed financing. They’re 300-500% markup over getting standalone coverage.
- Join a maintenance plan BEFORE you need repairs. Member pricing on capacitors, contactors, and refrigerant recharges pays for the plan in 1-2 calls.
- Register your warranty the day of install. Manufacturers void it after 60-90 days if unregistered. We do this for you — confirm you got the email.
- Use Florida’s 25C federal tax credit for qualifying high-efficiency systems (up to $2,000) — your installer should give you the form.
Red Flags to Watch For
- “Today only” pricing pressure. HVAC is a 12-year decision; no legitimate quote expires in 24 hours.
- Unwilling to give a written quote. A verbal “about $X” means nothing — get it on paper with a part/model list.
- Can’t produce a current Florida CAC license number. Search any contractor at myfloridalicense.com.
- Cash-only or deeply discounted “no permit” installs. Unpermitted work voids manufacturer warranties and fails home-sale inspections.
- Recommends replacement on a capacitor call. Capacitor fails → replace $200 part. If a tech says “your whole unit needs replacing” on a 3-year-old system, get a second opinion.
- Pressure to buy the largest unit. Oversized = shorter life + poor humidity control + higher bills.
- Won’t provide references from your neighborhood. Boca Raton, Boynton, Delray HVAC contractors should have 10+ verifiable local jobs to point at.
