Real HVAC Projects, Real Results
These are actual jobs we've completed in the OKC metro — with the problem, the diagnosis, the work performed, and the final outcome. No fluff, no stock photos, no marketing spin. Just honest documentation of how ARP solves HVAC problems.
Featured Case Studies
Details changed where needed to protect homeowner privacy. All outcomes and diagnostics are from actual ARP service calls.
Saturday Night AC Failure, 96°F — 30-Minute Arrival
📍 OKC Metro · Summer
Customer called at 6:45 PM on a hot Saturday. Charlie was at the door by 7:15 PM. Diagnosed a failed capacitor and had the AC cooling again within 45 minutes. Total cost: under $250.
Dual 20-Year-Old HVAC Systems Replaced in One Day
📍 Edmond / OKC metro · Multi-unit home
Homeowner had two aging HVAC systems on their last legs. Other contractors quoted $18,000-$22,000. ARP completed both replacements in a single day with premium equipment at a more reasonable price.
$2,500 "Repair" That Was Actually a $0 Fix
📍 OKC metro · Winter
Two contractors quoted $2,500-$3,500 to fix a heating issue. Charlie showed the homeowner how to resolve it for free — no parts, no labor, no bill. They came back years later for a full system when it was actually needed.
Furnace Won't Start? The $5 Fix vs. The $1,200 Misdiagnosis
📍 OKC Metro · Winter pattern
Three contractors quoted $700-$1,200 for a control board on a furnace that actually needed a $5 piece of tubing. The diagnostic ladder we walk before quoting anything, and why control board is the LAST thing we test, not the first.
What February 2021 Taught Us About Heat Pumps in Oklahoma
📍 OKC Metro · Reference event
When OKC hit -14°F overnight, standard heat pumps struggled and cold-climate units held up. Five years later, this case study covers what we changed in our heat pump sizing recommendations for Oklahoma homes, and why we now default to cold-climate or hybrid dual-fuel.
AC Can't Keep Up? It's Probably the Ductwork, Not the AC
📍 Midwest City / Del City · Tinker-era homes
A common pattern in 1950s post-WWII Tinker-area homes: modern AC bolted to undersized ductwork. The static pressure measurement that tells you whether to right-size the AC, resize the ducts, or rethink the whole airflow design. Three real fix options with real costs.
When the Wrong Rebate Gets Quoted on a Norman Heat Pump
📍 Norman · Cleveland County
Norman is genuinely split between OG&E and OEC, and the boundary isn't intuitive. Contractors who don't verify which utility a Norman homeowner actually has often quote the wrong rebate, leaving customers $400 short at install. How we verify utility identity before quoting.
Modern Equipment in an Older Nichols Hills Home
📍 Nichols Hills · 1930s-1960s housing
High-end customers in older homes wanting variable-speed, zoning, and whole-home humidification. The trade-offs that have to happen up front: tight mechanical rooms, mixed-era ductwork, marginal electrical service, and finished spaces with no obvious chase paths. Three-tier quoting with real numbers.
