HVAC in Rural Florence: What's Different About Servicing This Community
Florence is a small unincorporated community in northwestern Williamson County, straddling the US-183 corridor between Georgetown and Lampasas. The community sits at roughly 1,050 feet elevation on the edge of the Edwards Plateau — a transitional zone between the Hill Country and the Blackland Prairie that has a distinct effect on how HVAC systems perform and fail.
Florence's ZIP code (76527) covers a large rural swath of northwestern Williamson County with a mix of established farmhouses, acreage homesteads, and newer rural residential properties. Most homes sit on private well water rather than Georgetown municipal supply — this is a meaningful difference for HVAC maintenance, because well water in this area tends toward higher mineral content than the Edwards Aquifer water that Georgetown city users receive, creating even faster condensate drain scale buildup.
The Housing Stock: What We Actually See in Florence
Florence's residential base skews older than Georgetown proper. A substantial portion of the homes ProAir services in the Florence area were built between 1975 and 2005 — many with original ductwork that was designed for lower-efficiency equipment and hasn't been replaced or sealed. These older duct systems routinely lose 25–35% of conditioned air to unconditioned attic space, a figure that matters when you're running an AC unit hard through a Central Texas August.
The HVAC brands common in Florence reflect the era. We see a lot of aging Carrier WeatherMaker and York units from the late 1990s through mid-2000s, some of which are still running on R-22 refrigerant. The R-22 phase-out completed in 2020 means Florence homeowners with pre-2010 equipment face a real decision point: when refrigerant is needed, the cost of R-22 recharge has risen sharply, and parts availability is tightening. ProAir carries R-22 inventory for existing systems, but we give Florence customers an honest assessment of when the economics favor replacement over recharge.
Propane and Dual-Fuel Systems: Common in Florence
Florence's rural location means natural gas is not available to most properties — propane is the dominant fuel for heating. Dual-fuel systems (heat pump for mild weather, propane furnace for hard freezes) are common and practical given the area's weather pattern: Georgetown averages fewer than 10 days per year below 32°F, making heat pump operation efficient for most of the heating season, with the propane backup handling the rare sub-20°F events.
Servicing propane systems requires attention to fuel pressure, burner condition, and heat exchanger integrity that's somewhat different from natural gas work. ProAir technicians are experienced with propane-fired HVAC throughout rural Williamson County — we verify propane supply pressure on every furnace call, since low tank pressure (common at the end of a winter season) mimics control board failure symptoms.
The Agricultural Dust Factor
Florence's agricultural surroundings create a dust environment that suburban Georgetown neighborhoods don't experience. Caliche dust from unpaved roads, crop dust during harvest periods, and general open-land particulate loading means air filters in Florence homes load significantly faster than typical Georgetown suburban installation. ProAir recommends Florence homeowners check filters every 3–4 weeks during dry periods, rather than the standard 30–60 day cycle. A clogged filter in a 100°F July is the single fastest path to a frozen evaporator coil and a preventable breakdown.
Response Time Reality: What to Expect
ProAir dispatches from Georgetown, which puts most Florence addresses 35–50 minutes out under normal conditions. For same-day calls received before noon, we can generally reach Florence that day. For afternoon calls and non-emergency service, next-morning scheduling is common. Emergency after-hours calls to Florence receive priority dispatch, though response windows of 90–150 minutes are realistic for the most remote addresses in the 76527 ZIP.
We tell Florence customers upfront: if your system shows signs of struggling in early May (running longer, not quite reaching setpoint, making new noises), call us before summer peaks. A spring diagnostic in May is a 90-minute visit. A July emergency call during a heat wave — when every HVAC company in Central Texas is at capacity — is a different situation entirely. The best Florence HVAC call is the one that doesn't happen in July because the system was caught in spring.

Common HVAC Failure Patterns in Florence TX
Capacitor Failure on Aging Units
Florence's older Carrier and York units — many 15–25 years old — fail most commonly at the run capacitor. This is an $85–$150 fix that becomes a $1,500+ compressor replacement if ignored through a summer.
Condensate Drain Blockage (Well Water)
Florence well water's high mineral content builds calcium scale in condensate drain lines faster than Georgetown city water. Float switch shutdowns in July are frequently the result — preventable with quarterly drain treatment.
Frozen Coil from Dirty Filters
Agricultural dust loads in Florence cause filter restriction in 3–4 weeks. Restricted airflow freezes the evaporator coil — the system appears to be "broken" but unfreezes once the filter is changed. Easily prevented.
Propane Furnace Pressure Issues
Low propane tank pressure at season end mimics control board failure — the furnace won't ignite reliably. Before any propane furnace diagnosis, ProAir verifies supply pressure. Saves Florence customers from unnecessary part replacements.
R-22 Systems at End of Service Life
Pre-2010 equipment in Florence frequently uses R-22 refrigerant. With R-22 averaging $80–$120/lb vs $15–$20/lb for R-410A, a single recharge can cost $400–$600 — often approaching the economics of replacement. We give Florence homeowners straight numbers.
Duct Leakage in Older Homes
Florence homes built before 2000 commonly have duct systems leaking 25–35% of conditioned air into attics. This shows up as rooms that never get comfortable despite a system that "runs fine." Duct sealing typically delivers a 20–30% reduction in utility bills.
Serving Florence TX: Rural Service Area
Florence is a small community in Williamson County approximately 18 miles northwest of Georgetown on TX-195. ProAir serves Florence for all HVAC repair, maintenance, and installation work. Florence's housing is a mix of rural residential (older homes on acreage), newer exurban development, and agricultural properties. HVAC needs here span older R-22 split systems and package units in established homes to newer Carrier and Lennox equipment in recent rural-residential builds.
Well Water and HVAC in Florence
Unlike Georgetown's municipal water supply, many Florence properties are on private wells. Well water hardness in Williamson County can vary significantly — from moderate (5–8 GPG) to quite hard (15–20 GPG) depending on the specific aquifer stratum. Higher mineral content in well water accelerates condensate drain scaling compared to even Georgetown's municipal supply. Florence homeowners on well water should consider annual condensate drain treatment a non-optional maintenance item, not a nice-to-have.
Response Times to Florence
ProAir dispatches from Georgetown. Florence service calls typically run 25–40 minutes for dispatch. Same-day service is standard for calls received before noon. Emergency service is available for Florence residents at our standard emergency rates — a complete system failure in a Florence home gets the same priority response as a Georgetown call.
