Pricing & Service

Pricing & Service

Our diagnostic fee is a flat $89. It's waived when you approve the repair. You always see the flat-rate repair price before we start work.

No. Estimates for new AC or heat pump installations are always free and always in writing.

A modest emergency dispatch fee applies after 7 PM and on Sundays; Comfort Club members are exempt. We disclose it before we roll a truck — never on the invoice.

Most Volusia County emergencies see a tech within 2–4 hours, day or night. Comfort Club members get priority queue.

Yes. Financing plans start around $89/month with approved credit, and we can walk you through federal tax credits and utility rebates.

Repair vs Replace

Repair vs Replace

Once a system is 12+ years old, uses R-22 refrigerant, or has a repair cost above 30% of a new system, replacement is usually the better long-term math. We give you the numbers, not a sales pitch.

Typical service life is 12–15 years inland and 8–12 years on the coast, depending on maintenance and salt exposure.

For most Volusia homes, yes. Modern inverter heat pumps handle our mild winters comfortably and are cheaper to run than traditional AC + electric strip heat above ~25°F.

For most Volusia homes the sweet spot is SEER2 15.2–17. Higher ratings pay back well only if you're home during the day or have very high summer bills.

Comfort & Air Quality

Comfort & Air Quality

Because thermostats measure temperature, not humidity — and Florida's biggest comfort problem is humidity. A whole-home dehumidifier tied into your ductwork holds RH at 45–55% year-round.

45–55% is the comfort and mold-prevention sweet spot in a Florida home.

On the evaporator coil, yes — they prevent biofilm and keep the coil clean, which is a real efficiency and odor benefit. As whole-air disinfection they're marginal.

Every 30–60 days for 1" pleated filters, every 6–12 months for a 4–5" media cabinet. Coastal or pet homes: on the shorter end.

Sizing & Ductwork

Sizing & Ductwork

With a Manual J load calculation that accounts for square footage, insulation, windows, orientation, and internal loads. Oversizing is more common than undersizing and causes short-cycling and humidity problems.

No. Most homes only need it once every 5–10 years — or after renovation, water intrusion, or a rodent problem. If a company is pushing yearly cleanings, that's a red flag.

A UL-tested duct sealing system that atomizes sealant inside your ductwork to seal leaks from the inside. Often cuts duct leakage by 60–80%.

Maintenance

Maintenance

Twice a year in Florida — spring for cooling season, fall for heat mode. Our Comfort Club covers both visits plus priority scheduling.

Two annual precision tune-ups, priority scheduling, no after-hours fees, 15% off repairs, and multi-year discount on replacement equipment.

A well-executed tune-up catches weak capacitors, low refrigerant charge, blocked drains, and dirty coils — the four causes of ~80% of summer breakdowns.

Company

Company

Yes — Florida State-Certified HVAC/Mechanical Contractor (CAC# TODO-LICENSE). Certificate of insurance available on request.
