Frisco's HVAC Replacement & Service Specialists
Metroplex Air & Heat is based right here in Frisco — our home base, dispatching same-day from Legacy Dr.
Frisco is our dispatch base, and it's also where the newest housing stock in our service area lives, Starwood and Phillips Creek Ranch homes built in the last 10-15 years. The pattern we see constantly: a builder-installed system sized off a generic square-footage chart, not the actual duct run or window exposure, so the upstairs never quite keeps up on 100-degree afternoons. Frisco Square's older homes have the opposite issue, aging systems well past their expected service life.
"First company that actually explained why our old system was oversized. New one is quieter and our bill dropped almost 30%."
Most Frisco AC replacements we run are in Starwood and Phillips Creek Ranch homes where the original builder unit was undersized for the actual square footage from day one.
Frisco Square's older homes are where we replace the most aging furnaces, usually paired with a full duct inspection since the ductwork is the same age as the furnace.
Newer Frisco two-story homes benefit the most from zoning, since a single thermostat rarely keeps both floors comfortable in July.
Fixing a Starwood Home That Never Cooled Upstairs
A 2015 Starwood two-story where the upstairs bedrooms stayed 4-6 degrees warmer than the thermostat setting all summer.
Ran a full Manual J load calculation, found the original system undersized by nearly a full ton, and replaced it with a correctly sized variable-speed system plus zoning.
Upstairs and downstairs now hold within a degree of each other, and the homeowners' summer electric bill dropped by roughly a third.
Since our team is based here, most Frisco service calls get a same-day technician, and emergency no-cool calls during summer are prioritized first.
Builder-grade systems in Starwood and Phillips Creek Ranch are frequently sized to a generic square-footage estimate rather than an actual load calculation, which is why the upstairs zone struggles even though the unit itself isn't broken.
Full AC replacements we quote in Frisco typically run $6,500 to $13,500 depending on system size and efficiency tier, always based on an actual load calculation, not a square-footage guess.
Since our team dispatches from Frisco, most replacements are scheduled and completed within the same week, faster during emergency no-cool situations.
