Get your free estimateFast, Reliable AC Installation Across Murphy
Murphy runs on a narrow set of subdivisions built in the 1990s, and most of the air conditioners installed in those houses are now on borrowed time. If your system is loud, short-cycling, or simply won’t keep up in July, we install replacements sized to the house you actually live in, not the one on a spec sheet. Our technicians have up to 15 years of experience and know these floor plans and attics well. Call (833) 488-8546 for a free estimate. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.

Why Murphy Homeowners Call Benchmark AC Repair for AC Installation
Murphy is a built-out town. There’s no new construction pipeline refilling the housing stock, which means nearly every call we get here is for an existing house, an existing system, and an existing set of ducts. That shapes how we work.
We’re brand-neutral on installations. We service Carrier, Trane, and American Standard equipment regularly, so we’re familiar with what’s already in Murphy homes, but we don’t sell toward one manufacturer. The recommendation comes from what your house needs: load, duct capacity, electrical service, budget. Not what’s sitting in a warehouse.
Our technicians have up to 15 years of experience with residential systems, including the builder-grade 2.5 to 3 ton split systems with attic air handlers that are common throughout Murphy Farms, Rolling Ridge, and Maxwell Creek. We also handle furnace work, so the same contractor covers your heating and cooling instead of you vetting two specialists.
Response into Murphy is straightforward from Plano. Book an estimate and we’ll give you a fixed written price before any work starts. If you have questions before then, call (833) 488-8546. We answer 24/7.

Heat Pump Installation in Murphy
Heat Pump Installation in Murphy usually comes up when a homeowner wants one unit to carry both the long cooling season and the short heating side, and it makes sense in this climate. July highs near 96°F mean cooling capacity and attic insulation drive the design. The mild winters mean you don’t need a separate gas furnace to stay comfortable most years. The freeze events of 2021 and 2022 changed how people here think about heating though, so we verify low-temperature performance rather than assuming it. Typical heat pump installation in Murphy runs $3500 – $7500, and the written estimate sets the final price.
Sizing for a cooling-first climate
A heat pump sized for heating will be oversized for cooling, and oversized equipment short-cycles. We run a load calculation on the house, not a rule of thumb by square footage. That matters more here than in colder markets.
Freeze protection checks
After the hard freezes, we check line set insulation, drain line routing, and outdoor unit placement as part of the install. It’s cheaper to handle those details now than to chase a frozen coil later.
Ductless Mini Split Installation in Murphy
Ductless Mini Split Installation in Murphy solves a specific problem: rooms or additions that the central system was never designed to reach. A converted garage, a sunroom, a bonus room over the garage, or a second floor that never cools evenly. Mini splits skip the ductwork entirely, so you’re not fighting undersized flex duct to get air where it needs to go. Typical ductless mini split installation in Murphy runs $3500 – $7500 depending on how many zones and where the lines run, with the written estimate setting the final price.
Multi-level floor plans
A single-zone system in a two-story house is a compromise from day one. A ductless head on the upper floor lets the main system work less and short-cycle less. That extends its life.

Line routing in tight construction
Murphy homes are brick veneer on slab, so we plan the line set path before we cut anything. Attic and wall cavity access varies house to house. We look first.
Trusted Brands We Service in Murphy
We work on Carrier, Trane, American Standard, Bryant, Lennox, Goodman, Rheem, York, and Daikin equipment. That coverage matters in a town where the original builder-installed systems are now being replaced and homeowners want a technician who recognizes what’s already there. We don’t claim to stock parts locally. What we do is diagnose accurately and get the right parts ordered quickly, so a planned installation stays on schedule instead of stalling for a component. If your existing system is one of the nine brands above, you don’t need to wonder whether it’s covered. It is.

AfterCommon AC Installation Problems We See in Murphy Homes
- Undersized or leaky original flex ductwork. The duct runs installed in the 1990s rarely matched what the house needed, and thirty years of attic heat has made the joints worse. High static pressure means a new system can’t deliver its rated capacity.
- Single-zone systems fighting multi-level floor plans. One thermostat trying to satisfy two floors leads to short cycling and uneven temperatures. The equipment wears out faster than it should.
- Electrical panels from the 1990s. Many Murphy panels lack the capacity for modern high-SEER2 equipment. This is a pre-installation item, not something to discover on install day.
- Original builder-grade systems all hitting end-of-life together. Because Murphy was built out in a tight window, replacement happens in waves. A whole block can be due in the same summer.
Pricing for AC Installation in Murphy, TX
Typical AC installation in Murphy runs $3,500 – $7,500. Where you land in that range depends on tonnage, equipment tier, and whether ductwork or electrical work is part of the job. A like-for-like swap sits at the low end; adding a duct upgrade or a panel upgrade moves the number up. We give a written, fixed price after the load calculation and a look at your ducts and panel. The estimate is free and there’s no obligation. If the honest answer is that your existing system has another few years in it with a repair, we’ll say that. Call (833) 488-8546 to book.

FAQs About AC Installation in Murphy
Because the new unit is doing exactly what it was designed to do, and the ductwork is still the old problem. A modern system delivers rated capacity at the coil; undersized or leaky flex duct in the attic loses a large share of that before it reaches the rooms. The fix is a duct evaluation, not a bigger condenser.
Often yes, especially in 1990s panels that were sized for a standard builder-grade unit. High-SEER2 equipment can draw differently and adds control board load, so we check available capacity before quoting. If a panel upgrade is needed, it becomes part of the written estimate so there’s no surprise.
Probably around 2.5 to 3 tons, but that’s a starting point, not a conclusion. The right size comes from a load calculation that accounts for your attic insulation, window area, duct condition, and orientation. Guessing by square footage is how houses end up with equipment that short-cycles.
A straight swap is usually a single day. If ductwork or an electrical panel upgrade is part of the scope, plan on longer, and we’ll give you the timeline with the written price before we start. Tight, low-clearance attics under radiant-barrier decks can add time to the air handler work.
We don’t recommend it. The condenser and evaporator coil are matched as a system, and a mismatched pair loses efficiency and can void the equipment warranty. On a 1990s Murphy system the indoor coil is typically the same age as the outdoor unit, so replacing one without the other usually leads to a repeat call.
