Emergency HVAC Services in Upper Darby
No cooling in a July heat wave or no heat on a school morning — our emergency HVAC services cover the township with fast response any time, and stocked trucks mean most calls end in a same-day fix, not a parts order.
Heating Repair & Replacement for Upper Darby Homes
Gas furnaces, radiators on original boilers, electric baseboard — the township runs on all of it, and we service all of it. Straight repair-vs-replace numbers when a system passes 15 years: heating repair and heating installation.
Air Conditioning Repair & Installation in Upper Darby, PA
AC Repair
Warm air, weak flow, ice on the lines, breakers tripping — we diagnose before we replace anything. Same-day air conditioning repair across the 19082.
AC Installation
Replacing a tired central system or cooling a rowhome for the first time, we size the equipment for the actual house — party walls, small footprints, and third-floor bedrooms included. Air conditioning installation with financing available.
Gas Line Repair & Leak Detection in Upper Darby
Much of Upper Darby’s gas infrastructure is as old as its housing stock, and a gas smell is never a wait-and-see problem: leave the house, call PECO’s emergency line, then call us. Our master plumbers handle gas line repair, replacement, and leak detection for appliances, heaters, and whole-house lines across the township.
Water Heater Repair & Installation in Upper Darby
Most tank replacements are done in 2-3 hours — same-day when you call early. In tight rowhome basements, tankless water heaters keep winning the space argument: endless hot water off the wall, zero floor footprint.

Furnace Repair & Replacement in Upper Darby: Gas, Oil, Electric
Gas, oil, and electric furnaces all run this township — and at 15+ years old, or when a repair passes a third of replacement cost, replacement wins the math. We quote both, on the spot.
Gas Furnace Services
From ignitors to full replacements — most of Upper Darby runs on gas, and our trucks carry the parts. Gas furnace repair and installation.
Oil Furnace Services
Burner repairs, tune-ups, and efficient replacements that cut fuel use — including oil-to-gas conversion quotes when the math favors switching. Oil furnace services.
Electric Furnace & Heat Pump Services
Quiet electric heat, repaired and maintained — or upgraded to a cold-climate heat pump that heats and cools from one system. Heat pump services.
Ductless Mini-Split Installation in Upper Darby
Rowhomes and twins built before ductwork existed don’t need demolition to get central-quality cooling — one outdoor unit, discreet wall heads room by room. Mini-split installation & replacement, heating included for winter.

HVAC at Township Scale: Upper Darby’s Rowhomes, Twins & Apartments
Upper Darby is Delaware County’s biggest township — 85,000 people in everything from 69th Street’s pre-war rowhomes to post-war twins in Stonehurst and Highland Park to multi-family buildings along West Chester Pike. These homes bring real HVAC challenges: undersized returns, tight mechanical closets, and no room for traditional ductwork — which is exactly why cookie-cutter HVAC fails here. We work these blocks every week, sizing ductless systems for homes that never had ducts, swapping crowded-basement tanks for tankless units, and keeping decades-old heating alive until replacement actually makes financial sense. Landlords and property managers: we service multi-unit buildings on maintenance schedules that keep tenants comfortable and phones quiet.
Upper Darby HVAC Questions, Answered
Our Delaware County trucks dispatch daily and carry the most common parts for Carrier, Trane, Lennox, and other major brands, so most emergency calls in Upper Darby get same-day service — usually fixed in the first visit.
Leave the house immediately without flipping switches or using phones inside, then call PECO’s gas emergency line from outside. Once the utility clears the property, our master plumbers can locate the leak, repair or replace the line, and pressure-test the system before your gas is restored.
Yes — ductless mini-split systems deliver central-quality cooling and heating room by room from one outdoor unit, with no wall demolition. They’re the standard upgrade for Upper Darby’s pre-war rowhomes and twins, and installation typically takes one to two days.
