HVAC Company in Heathrow, FL
HVAC work in Heathrow, FL comes down to one thing: heat and humidity that don’t let up for months at a time. Homes here run their air conditioning hard from April through October, and when a system fails, it fails fast. Dalton Heating & Air handles AC repair, heat pump installation, and furnace repair across Heathrow with written pricing before any work starts and a full-year written guarantee on every repair. Call (361) 306-9515 when your system stops keeping up.
Why Heathrow Homes Are Different
Heathrow sits in Seminole County, just north of Lake Mary, and the housing stock reflects a specific era of Central Florida building. Most homes went up between the late 1980s and early 2000s, which means two things for HVAC work. First, a lot of the original equipment is now past its expected service life, so we see compressors and air handlers that have been running for 15 to 20 years. Second, many of these homes were built with ductwork sized for older, less efficient systems, which matters when a homeowner upgrades to a modern heat pump and wants the airflow to match.
The terrain here is flat and the lots are generous, often with mature oak canopies. That shade helps with cooling load, but it also drops leaves and debris onto outdoor condenser units. We regularly clean coils in Heathrow that are packed with oak litter, which drives up head pressure and shortens compressor life if left alone. Homes in communities like Heathrow Woods, Alaqua Lakes, and the gated sections along Markham Woods Road tend to have higher-end equipment and tighter HOA rules about outdoor unit placement, so installations often require coordination on where a condenser can sit and how linesets are routed.
Our Main Heathrow Services
These are the three jobs Heathrow homeowners call us about most. Each has its own page with full pricing, timelines, and what to expect on the day of service.
AC Repair in Heathrow
When a central air system fails in a Heathrow summer, the house becomes uncomfortable within hours. Most AC repairs we handle here are refrigerant leaks, failed capacitors, condenser fan motors, and clogged drain lines. A common Heathrow-specific issue we see is drain line blockages from the humidity and organic matter that collect in the PVC condensate lines, which trips float switches and shuts systems down. We diagnose the problem, put the repair price in writing, and complete the work same-day in most cases. AC Repair in Heathrow covers what we fix, what it costs, and how fast we can get there.

Heat Pump Installation in Heathrow
Heat pumps handle both cooling and heating, which fits Heathrow’s climate well: long cooling seasons and short, mild winters that rarely dip below freezing. A properly sized heat pump can cut energy use meaningfully compared to an older straight-cool system with electric strip heat. In Heathrow, we pay close attention to duct sizing and static pressure on installs, because many original duct systems were marginal from day one. We offer fixed written quotes with a set install date, never a same-day install promise on a system that needs load calculation and permits. Heat Pump Installation in Heathrow has full pricing and the brands we install.

Furnace Repair in Heathrow
Furnaces here don’t work as hard as they do up north, but the few cold nights Heathrow gets each year are exactly when a furnace shows its age. Most furnace repairs in the area involve ignitors, flame sensors, gas valves, and blower motors on systems that have sat idle for months. A furnace that hasn’t run since February will sometimes fail on the first cold snap in December, and when it does, you want a technician who can diagnose it the same day. Furnace Repair in Heathrow covers common failures, pricing, and our repair guarantee.

What pushes a Heathrow job toward the higher end is usually equipment access: units in attics with tight clearances, condenser pads tucked against fence lines, or ductwork that needs correction during an install. A system that’s been running for two decades with deferred maintenance often needs more than a single part replaced, and we quote that work honestly before we touch anything. Every price is in writing before work begins, and every repair carries a written guarantee for a full year.
