AfterHVAC Company in Murphy, TX
Murphy homeowners face a unique challenge: most houses here were built between 2000 and 2015 with builder-grade HVAC systems now hitting the 12-to-20-year replacement window all at once. Coldharbour Heating & Air handles this concentrated wave of aging equipment with technicians who know the specific quirks of Murphy’s two-story brick homes, undersized original systems, and the North Texas clay soil that shifts ductwork year after year. Call us at (817) 402-2972 for a free estimate, any time of day.
Why Murphy Homes Are Different
Murphy’s entire residential buildout happened in an extraordinarily compressed window, roughly 2000 to 2015. Unlike neighboring Plano or Garland, where housing vintages span decades, Murphy is essentially a single cohort of homes. That means the overwhelming majority of HVAC systems were installed with the same builder-grade specifications and are now failing simultaneously, creating intense seasonal demand surges.
The housing stock is almost entirely 2,500-4,000 square foot two-story brick suburban homes built during the Collin County growth boom. Production builders commonly fitted these large layouts with single-zone or undersized two-zone systems to hit price-point targets. Local technicians regularly find 3-ton units in homes that properly load-calculate to 4 tons, which explains why upstairs bedrooms in Avalon, Maxwell Creek, and similar master-planned communities run 5-8°F hotter than the thermostat shows, and why those same compressors burn out prematurely from constant overwork.
Murphy sits on the North Texas Blackland Prairie, where shrink-swell clay soils cause measurable slab movement. That movement stresses ductwork boots and air handler connections over time. Summers regularly push past 100°F, and when Gulf moisture surges northward, humidity spikes compound refrigerant charge issues quickly. Equipment here logs punishing runtime hours compared to milder climates.
Our Main Murphy Services
Most calls we get from Murphy fall into three categories: emergency cooling repair during peak summer, furnace service before the first cold snap, and full system replacement for homes facing their first-ever install.
AC Repair in Murphy
AC repair in Murphy typically involves compressor failure from chronic overwork, refrigerant leaks at coil connections stressed by vibration, or capacitor and contactor failure after long summer run cycles. We see a lot of upstairs comfort complaints rooted in undersized original equipment rather than simple mechanical breakdown. Our technicians carry common Goodman, Rheem, and York parts so most AC Repair in Murphy jobs finish same-day.
Furnace Repair in Murphy
Furnace repair in Murphy centers on igniter failure, flame sensor buildup, and heat exchanger stress from short-cycling in homes where the original system was never properly sized for the square footage. Because Murphy’s build window was so tight, we see the same furnace models failing with the same patterns across entire subdivisions. We stock igniters, control boards, and inducer motors for the brands most common here. Schedule Furnace Repair in Murphy and we’ll give you a written price before any work begins.
AC Installation in Murphy
AC installation in Murphy is increasingly a replacement of the original builder unit with properly sized equipment. We run a full Manual J load calculation on every home, and we regularly find that a 3-ton system needs to become a 4-ton with proper zoning to solve the upstairs heat load. We handle rebate and financing paperwork, and we schedule installation for a fixed date after equipment is ordered, never promising same-day on a job that requires measurement and planning.

What pushes Murphy prices toward the higher end: properly sizing replacement equipment for two-story homes often requires upgrading electrical connections and modifying ductwork, and clay soil movement can add labor to duct boot repairs. Every job gets a written price before any work begins, and that price does not change when the technician arrives. That’s The Kingswell Way, not a policy we apply case by case.

Some do, some don’t. Avalon and Maxwell Creek have architectural review requirements for exterior condenser placement, but permit handling varies by subdivision. We pull all required city permits as part of any AC installation and can submit HOA paperwork if your community requires it.
This is the most common comfort complaint in Murphy. Original builder systems were frequently undersized for actual square footage, and single-zone ductwork cannot overcome the heat load on a 3,500 square foot two-story home. A proper load calculation almost always reveals the unit is a half-ton to a full ton too small for the space.

What Murphy Customers Say
"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
