AfterHVAC Company in Lake Mary, FL
Most HVAC service calls in Lake Mary run $150-$700 for repairs and $3,500-$7,500 for full system replacements, with same-day response available when you call (817) 402-2972. Lake Mary’s master-planned communities built between 1988 and 2005 present a unique challenge: thousands of original R-22-era systems are aging out simultaneously, and nearly every replacement must clear both Seminole County permits and strict HOA architectural covenants. We’re Coldharbour Heating & Air, and our technicians handle that dual-approval process regularly.
Our dispatch and scheduling are coordinated from our Miami office, with crews serving Lake Mary homes directly. Every repair comes with a written price before work begins and our 365-Day Done Right Promise in writing before the technician leaves.
Why Lake Mary Homes Are Different
Lake Mary was engineered as an upscale corporate suburb, and that planning shows in every service call we make. The dominant housing stock runs 2,500-4,500 square feet in gated and planned communities, almost always with air handlers tucked into unconditioned attics that hit 140°F regularly from May through September. That attic heat degrades ductwork faster than conditioned-space installations, so we inspect flex runs and plenum connections on nearly every visit, not as an upsell but as a necessity.
The city’s dense network of retention ponds and lakes keeps humidity elevated even by Central Florida standards. Your system’s dehumidification capacity works harder here, and condensate drains clog with algae and mold more frequently than in drier inland markets. Add the I-4 corridor’s afternoon lightning pattern, and you get predictable summer surges in control board and capacitor failures.
Then there’s the HOA layer. Required landscaping screens around outdoor condenser units, meant to hide equipment from street view, often get overgrown or planted too close by homeowners trying to satisfy covenant inspectors. The resulting airflow restriction causes high-head-pressure lockouts that less experienced techs misdiagnose as refrigerant loss or compressor failure. We check clearance and screen condition before touching the refrigerant circuit.
Our Main Lake Mary Services
These are the three calls we handle most often in Lake Mary, each with its own dedicated page and local pricing.
AC Repair in Lake Mary
AC repair in Lake Mary typically involves capacitor and contactor replacements after lightning strikes, refrigerant leaks in aging R-22 systems, and condensate drain clearing in high-humidity conditions. We carry capacitors, contactors, and hard-start kits for Rheem, York, Daikin, Bryant, and other major brands on every truck, so most single-part repairs finish in one trip. AC Repair in Lake Mary
Furnace Repair in Lake Mary
Furnace repair in Lake Mary centers on igniter failures, flame sensor cleaning, and heat exchanger inspection in the gas furnaces common to homes built in the 1990s and early 2000s. Even in Central Florida, a January cold snap with a failed furnace is miserable, and we treat no-heat calls with same-day priority when safety is a factor. Furnace Repair in Lake Mary
AC Installation in Lake Mary
AC installation in Lake Mary requires navigating Seminole County permitting and HOA architectural review boards before equipment ever gets ordered. We handle the paperwork, submit equipment cut sheets for covenant compliance, and schedule installation only after approvals clear. Most Lake Mary replacements involve two systems for zoning in larger homes, with ductwork replacement recommended given attic heat degradation. AC Installation in Lake Mary

What pushes Lake Mary prices toward the higher end: dual-system homes requiring twice the equipment, HOA-mandated equipment screens or pad relocation, and ductwork replacement in degraded attic runs. What keeps them lower: single-part repairs with parts on the truck, straightforward access, and systems that don’t need refrigerant conversion.

Almost certainly yes. Lake Mary’s master-planned communities require architectural review board approval for outdoor equipment changes, including condenser unit location, pad type, and screening. We submit cut sheets and placement drawings as part of our standard installation process, and we don’t order equipment until approvals clear. This adds time but prevents covenant violations and forced re-dos.
Lake Mary’s combination of unconditioned attic installations, elevated humidity from retention ponds, and I-4 corridor lightning exposure creates a harder operating environment than many Orlando homes face. The 140°F attic temperatures degrade ductwork and strain air handlers, while summer storms fry control boards. Regular tune-ups catch deterioration before it becomes failure, and our $80-$200 tune-up includes a full written report of what we find.

What Lake Mary Customers Say
"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
- Natalie Esposito"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
