Greenville's median home was built in 1978. That means the HVAC systems in this city span every era of residential heating and cooling technology — from late-1970s gravity furnaces and early central air installations to 1990s R-22 systems now restricted from recharging to 2000s-era equipment approaching end-of-life. Greenville homeowners and landlords need an HVAC team that knows how to work honestly in an older housing market — not one that sees a 40-year-old home and immediately recommends replacing everything. We assess what's actually wrong, tell you your real options, and let you decide.
Unlike the Collin County suburbs where HVAC challenges cluster around a single construction era, Greenville's HVAC market is genuinely diverse. Here's what each era looks like:
These are Greenville's oldest properties — and they present the greatest HVAC complexity. Original central air, if it was even installed, may have been retrofitted into a home designed for window units or radiant heat. Ductwork in these homes is often undersized, poorly insulated, and running through unconditioned spaces in ways that make every modern system work harder than it should. Before recommending any system replacement in a pre-1970 Greenville home, we assess the duct system — because installing a new system into a fundamentally flawed duct configuration wastes the entire investment.
Homes from this era commonly have original or once-replaced HVAC equipment that is approaching or past end-of-life. Many have duct systems from the same era — early flex duct or duct board that has been through 40+ Texas summers in uninsulated or poorly insulated attics. R-22 systems installed as recently as the late 1990s in these homes are restricted from recharging. Honest assessment: many 1970s–1980s Greenville homes need both system and duct replacement for meaningful improvement — but we prioritize based on what's actually failing rather than recommending everything at once.
The growth wave that added 25%+ of Greenville's housing stock in the 1990s and 2000s produced systems that are now 15–30 years old. First replacement cycle for the late-1990s group, second major service phase for the early-2000s group. R-22 prevalence is high in this cohort.
With nearly half of Greenville's housing renter-occupied, the landlord HVAC market here is substantial — and chronically underserved. Tenant calls about AC failures in July are emergencies that cost landlords in multiple ways simultaneously: tenant inconvenience damages relationships, emergency service pricing is higher than scheduled, and deferred maintenance on older rental HVAC systems turns a $300 repair into a $3,000 replacement.
We offer Greenville landlords the same portfolio approach we describe in our plumbing pages: priority tenant response, pre-tenancy HVAC inspections, capital planning for aging systems across multiple properties, and honest condition assessments that help landlords make informed decisions about repair vs. replacement timing across their inventory.
Every other HVAC company in Greenville does only HVAC. Every other plumbing company does only plumbing. Everflow does both — and that matters more than most homeowners realize.
Air conditioning systems and plumbing are more connected than they appear. Condensate drain lines, humidifier systems, and gas line connections span both trades. When something goes wrong at the intersection — and it happens regularly in older homes — most homeowners end up calling two different companies. Our customers call one number and get one team.
All major brands including older equipment. We don't decline service calls on older systems the way some companies do — we assess honestly and tell you where the system actually stands.
Gas and electric. Greenville's 1970s–1980s homes sometimes still have original furnaces approaching 40+ years old. We assess condition honestly — some older furnaces are repairable and have remaining useful life; others are safety concerns with cracked heat exchangers that warrant immediate replacement.
Greenville's most underdiagnosed HVAC problem. Replacing a new system into a 40-year-old deteriorating duct system dramatically underperforms the efficiency potential of the new equipment. We assess duct condition independently and tell you whether duct replacement adds enough value to justify the cost in your specific situation.
For Greenville's high concentration of R-22 systems, we explain the economics clearly without pressure. Some older R-22 systems that are running well and not leaking are worth maintaining for another few years. Ones that are leaking need replacement decisions made on real cost data.
For Greenville's budget-conscious homeowners replacing both AC and furnace simultaneously, a heat pump system can deliver meaningful long-term operating cost savings. We run the numbers honestly.
Priority tenant response, pre-tenancy inspections, portfolio capital planning. Greenville's landlord community is an underserved market we actively want to serve.
