We’re Dalton Heating & Air, a Garrison Partners company in operation since 2003, and we run every job under The Garrison Standard: written price before we start, uniformed technicians who show up inside the stated window, and a written one-year guarantee on every repair. Call (361) 306-9515 and a live person answers, 24/7.
Why Dalton Heating & Air Is Longwood’s Preferred AC Repair Company
Longwood homeowners call us because we show up and we get it right. Our Longwood customers back that up in the reviews they leave after every job. We respond to the whole Longwood area, from the subdivisions off Markham Woods Road to the neighborhoods around Wekiva Springs and the 32779 zip code, with techs who know this housing stock. The homes here are a mix of 1980s and 1990s ranches and newer two-story builds, and the strain on condensers sitting in full sun near State Road 434 is real, especially in August.
Our techs are factory-trained on nine major brands, including Carrier, Trane, and Rheem, so the diagnosis is correct the first trip. Before any work begins, you get the price in writing. If the repair fails within the guarantee period, we return at no charge. That’s not a policy we advertise here and ignore there. It’s The Garrison Code, and every Dalton location operates under it.
Marco Benitez leads our crews. He holds every tech to the same standard: arrive inside the window, diagnose by the book, price it in writing, fix it, and clean up.
AC Maintenance in Longwood
AC Maintenance in Longwood is the difference between a system that lasts 8 years and one that lasts 15. In our service area, we do a full maintenance visit in about an hour: coil inspection, drain line flush, capacitor test, refrigerant check, and a written report of what we found and what it means. Most tune-ups in Longwood run $80 – $200, and the report is yours regardless of whether you book any follow-up work.
Pre-Summer Tune-Up
Before the Longwood heat hits in May, the smart move is a capacitor test and a coil rinse. Longwood gets more than its share of storms, and surges that trip breakers also weaken capacitors. A $20 part caught in May saves a $500 repair in July.
Drain Line and Airflow Check
Humidity in Longwood means algae grows in PVC condensate lines fast. We flush the line, check the float switch, and verify static pressure so the blower isn’t working against a restricted coil. That’s a common cause of freeze-ups we see in older Longwood homes.
AC Service in Longwood
AC Service in Longwood means a diagnostic visit with a defined scope, not an open-ended ticket. We show up, run the capacitor, check refrigerant pressures and superheat, inspect the contactor and fan motor, and tell you what’s failing and what it costs before you approve anything. A diagnostic service call in Longwood runs $80 – $200, and that fee is credited toward the repair if you move forward.
Diagnostic Visit
The diagnostic is the backbone of our service. On a no-cooling call in Longwood, we start with the capacitor because storms here routinely stress that exact part. Five minutes on the multimeter tells us whether you’re dealing with a weak capacitor, a low charge, or a locked compressor.
Repair Follow-Up
After we fix it, you get the written guarantee. If the same repair fails at any point in the next 365 days, we return at no charge. That’s the 365-Day Done Right Promise, written into every ticket in Longwood.
Trusted Brands We Service in Longwood
We’re factory-trained to service Trane, Lennox, Goodman, and Rheem systems in the Longwood area, and we stock common parts for these brands, including capacitors, contactors, and fan motors, so most repairs are same-day. Longwood homeowners with a 10-year-old Trane heat pump or a builder-grade Goodman condenser get the same written pricing and warranty terms as every other job. When a part isn’t on the truck, we have local supply houses serving the Longwood area, not a warehouse three counties away.
Common AC Repair Problems We See in Longwood Homes
- Capacitor failure after storms. Longwood sits directly under the Orlando metro’s lightning belt. A surge can weaken or swell a run capacitor, and the system won’t start or will short-cycle until it’s replaced.
- Oversized units that were never load-calculated. In Longwood’s mix of older subdivisions and newer builds, many condensers were sized by square footage alone. The result is short cycling, higher humidity indoors, and bigger electric bills.
- Refrigerant issues misdiagnosed as leaks. Our techs regularly find that a low charge isn’t a leak at all. It’s a factory undercharge or a hidden evaporator coil restriction that a static pressure check reveals in minutes.
- Clogged condensate lines from high humidity. Longwood’s wet summers grow algae quickly. A clogged line trips the float switch, kills the system, and can dump water into a ceiling or closet if it’s been ignored.

FAQs About AC Repair in Longwood
We check the capacitor first. Longwood’s storm activity means power surges routinely weaken or swell capacitors, and a failed run capacitor will let the fan run while the compressor never starts. After that we check refrigerant pressures, the contactor, and the thermostat signal. Call (361) 306-9515 and we’ll walk you through what we’re seeing.
If your current system short-cycles, leaves rooms humid, or runs constantly in peak heat, the tonnage was likely never matched to your home’s actual load. A Manual J load calculation measures your home’s insulation, window exposure, and duct condition in Longwood’s climate. It’s the only honest way to size a replacement. We will not install a new system without one.
SEER2 measures cooling output per watt consumed under the new testing standard that reflects real-world duct losses. In Longwood’s cooling season, going from a 13 SEER2 unit to a 17 SEER2 unit can cut the cooling portion of your bill by roughly 20 – 25%, depending on your home’s ductwork and air leakage. The number isn’t marketing; it shows up on your bill every month.
Repair is usually the right call when the compressor is healthy, the unit is under 10 years old, and the repair total stays under $650. Replacement makes sense when the compressor has failed, the system is over 12 years old, or the repair cost exceeds about 40% of a new system’s price, which in Longwood runs $3,500 – $7,500 installed. We’ll give you the real numbers on both options before you decide.
Yes. We service ductless mini splits and heat pumps in Longwood, including brands like Daikin and Mitsubishi. The big advantage for Longwood homes is zoned cooling without duct losses, which matters in the area’s shoulder seasons when you only need one or two rooms cooled. Same written pricing and one-year guarantee apply to every mini split and heat pump repair.
