Mini Split Installation in Irving, TX

Two Irvings

Few cities on this site split as cleanly. Irving contains a dense corporate district and a postwar residential neighbourhood, and they generate completely different ductless work.

Las Colinas and the DFW Airport corridor is one of the largest business districts in Texas — corporate headquarters, office towers, flex buildings, and data infrastructure. The ductless demand here is commercial: server rooms, IT closets, tenant suites, and spaces whose cooling needs do not match what the base building system provides.

South Irving, Irving Heights, and Plymouth Park are 1950s and 60s residential, now 60 to 70 years old, with the aging-ductwork problem that comes with that age.

Server rooms are the signature Irving job

This is where Irving differs from every other DFW city we cover, and where the money is most often wasted through one specific oversight.

The scenario is familiar: the building HVAC shuts down at 6pm and on weekends. Your equipment does not. A dedicated ductless unit runs on your schedule, independent of the base building system.

Specify a low-ambient kit. This is the mistake we see most. A standard mini split is designed to cool when it is hot outside. It is not designed to produce cooling at 40°F ambient — and that is precisely when your servers are still throwing off the same heat they do in July. A low-ambient kit adds a crankcase heater and head-pressure fan control, extending operation to roughly 0°F. Without it, the system fails you on the first cold night in November.

Size on heat output, not square footage. Add up the wattage of everything in the room and multiply by 3.41 for BTU per hour, then add 20 percent. A 3,000 W rack load means roughly 10,200 BTU/hr, so a 12,000 BTU unit is the floor. Server rooms are the one application where erring slightly large is correct — the cost of being wrong is hardware.

Consider redundancy. For anything business-critical, two smaller units beat one large one. A failure leaves you with degraded cooling rather than none, and you can service one without shutting down.

Plan the condensate drain. A unit running year-round produces water year-round, in a room full of electronics. A condensate pump with an alarm float is inexpensive insurance.

Tenant considerations in Las Colinas

If you lease your space — most Las Colinas tenants do — get landlord approval in writing before any work, and settle four things in it:

• Where the outdoor condenser goes
• Who owns the equipment at lease end
• Who is responsible for roof or wall penetrations and their repair
• Whether work must be done after hours

Also confirm electrical capacity early. Leased suites are frequently built out with panels sized precisely for the original tenant with no spare capacity, and a service upgrade in a commercial building is a considerably larger project than in a house.

Commercial permits in Irving follow a separate track from residential and often require sealed drawings for larger systems. Use a contractor comfortable with that process — it is meaningfully different from residential work.

South Irving’s ductwork

The residential half of the city has the same issue as Garland and Arlington: housing old enough that the duct network is the limiting factor, not the equipment.

Irving Heights, Plymouth Park, and the South Irving neighbourhoods date from the 1950s and 60s. Condensers and air handlers have been replaced once or twice over the decades. The ductwork — original, in an unconditioned attic — usually has not.

Duct systems of that age in Texas attics commonly leak 20 to 30 percent of conditioned air. Settle it with a duct leakage test rather than a sales conversation. If the ducts test tight, a high-efficiency central replacement is likely the better value. If they leak badly, you are choosing between rebuilding the network and eliminating it — see whole-home ductless and the central AC comparison.

For many South Irving homes the practical answer is a hybrid: keep the central system for the main body of the house, add ductless zones for the converted garage, the back bedroom, or the addition that was never properly tied in.

Rental and multifamily

Irving has a substantial rental market, particularly in Valley Ranch and the corridors near the airport. Ductless suits rental property well — independent zoning per unit, no shared ductwork transferring noise or odours between units, unit-by-unit replacement, and nothing to clean between tenants. Permitted work matters here for insurance and resale.

Oncor rebates

Unlike neighbouring Garland, which runs its own municipal utility, and Denton, which runs DME, Irving is in Oncor’s delivery territory. The standard DFW program applies: up to $600 per qualifying heat pump, requiring 16 SEER2 or better equipment, an Oncor-approved contractor, and a DOE-listed smart thermostat.

Oncor is your delivery utility regardless of which retail provider bills you. Applications run February through November and close December 1 or when annual funding runs out.

For commercial and multi-unit installations, the rebate is structured per qualifying heat pump, so a multi-unit project may claim more than one — confirm with Oncor, since rules for non-owner-occupied property differ.

The federal 25C credit expired December 31, 2025.
