Winter Gardens runs on rooftop package units. Most homes here were built between the 1950s and 1970s as single-story ranch houses on slab foundations, and many still carry the original rooftop equipment or a horizontal furnace tucked into the attic. That changes how HVAC work gets done: rooftop access, salt air corrosion, and ductwork that was sized for a different era. We’re Coldharbour Heating & Air, and we handle AC repair, furnace repair, and AC installation across Winter Gardens with written pricing and a 365-day repair guarantee. Call (619) 793-3598 and a live person answers.
Why Winter Gardens Homes Are Different
The marine layer is the quiet variable in Winter Gardens. Mild coastal weather means cooling loads stay moderate, but the humidity and salt exposure never stop working on equipment. Condenser coils corrode faster here than they do ten miles inland. Contacts and terminals oxidize. Condenser fan motors seize after months of sitting idle. The pattern we see every year: the first warm day after a long stretch of marine layer, and suddenly every AC unit that sat unused through the gray weeks fails at once. Corroded contacts and seized motors are the usual culprits.
Short cycling is another Winter Gardens signature. Because temperatures rarely swing hard, systems switch on and off more often than they were designed to. That repeated cycling wears contactors, capacitors, and fan motors earlier than the calendar suggests. Rooftop package units take the brunt of it, sitting in direct sun and salt air. And the ductwork in these mid-century homes was often sized for older equipment. When a modern system goes in, airflow and static pressure need to be checked carefully, or the new unit underperforms and the house never quite cools evenly. None of this is unusual to us. It’s the standard Tuesday in Winter Gardens.
Styles & brands we work with







Our Main Winter Gardens Services
Most calls we take in Winter Gardens fall into three buckets: an AC that quit on the first warm day, a furnace that won’t light on a cold night, or a rooftop unit that’s reached the end of its run. Each service has its own dedicated page with pricing, timelines, and what to expect.
AC Repair in Winter Gardens
Rooftop package units dominate AC repair calls here, and salt air corrosion is the leading cause of failure. Seized condenser fan motors, corroded contactors, and low refrigerant from slow leaks at brazed joints are the most common diagnoses in Winter Gardens. We inspect the entire system, not just the part that failed, because coastal corrosion rarely stays in one place. Every repair comes with a written 365-day guarantee. If it fails inside that year, we return and fix it at no charge. Full details on pricing and timelines are on the AC Repair in Winter Gardens page.

Furnace Repair in Winter Gardens
Horizontal attic furnaces are the norm in these ranch homes, which means furnace work often happens in a tight crawl space with a headlamp. Igniters, flame sensors, and gas valves take priority in Winter Gardens because the marine layer leaves moisture in the attic air, and moisture accelerates failure on electrical ignition components. We work on all major brands and stock common parts locally so most furnace repairs in Winter Gardens are completed in a single visit. See the Furnace Repair in Winter Gardens page for repair costs and what a typical job involves.

AC Installation in Winter Gardens
Replacing a rooftop package unit on a 1960s ranch comes with a specific set of considerations: roof curb condition, crane access, ductwork that may have been undersized from the start, and coastal-grade components that will hold up to salt air. We don’t rush any of it. Every installation begins with a home assessment and a written fixed price before any equipment is ordered. Homeowners in Winter Gardens get a set install date and clear paperwork on rebates and financing. The AC Installation in Winter Gardens page covers replacement costs, system options, and what makes coastal installations different.

Salt air corrosion is the biggest price driver in Winter Gardens. A contactor replacement is quick, but a condenser fan motor seized from months of coastal exposure costs more in parts and labor. Outdoor units here also need more frequent coil cleaning than inland systems. Whatever the job, you get a written price before any work begins. That price does not change at the door.

What Winter Gardens Customers Say
"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
- Doug Feeney"Signed up for a tune up before summer. He found a part starting to fail and showed me the reading, didn't just tell me to trust him. Fixed it then so we wouldn't get stuck in July."
- Sophia Tran"Our upstairs never cooled right. He found the duct run was half blocked and the system low on charge, fixed both, and now the whole house is even. Explained every step."
