HVAC Company in Florence, TX
Most HVAC work in Florence runs $150-$700 for repairs and $3,500-$7,500 for full system replacements, with same-day service available when your AC quits in July or your furnace fails during a hard freeze. Coldharbour Heating & Air dispatches technicians trained for Florence’s specific challenges: propane-fired equipment, aging rural ductwork, and the clay-soil foundation shifts that separate ducts in older slab homes. Call us at (817) 402-2972 for a free estimate or to schedule a repair.
Why Florence Homes Are Different
Florence sits in rural Williamson County without a municipal natural gas network, so most homes here run on propane or all-electric systems. That changes nearly every service call we make. A technician driving up from Georgetown expecting a standard gas furnace swap will find a propane conversion, tank coordination, and different venting requirements instead.
The housing stock splits sharply. Older farmhouses and ranch-style slab homes, many built before 1980, carry undersized or retrofitted ductwork that was never designed for modern cooling loads. Manufactured homes make up a significant share of the market too, with their own sizing and duct-integrity limits. Meanwhile, new construction along the US-183 corridor brings suburban expectations to a rural grid that can strain under August demand.
Central Texas summers push systems to near-peak capacity for four straight months. Winter Storm Uri in February 2021 proved the other edge: heat-pump refrigerant lines froze, pipes cracked, and homeowners learned which systems had real low-ambient protection. Florence’s clay-heavy and caliche soils shift seasonally, and we’ve found flexible duct connections at the plenum kinked or separated in home after home. A tech who doesn’t check that specific failure mode will miss the root cause of poor airflow.
Our Main Florence Services
Florence homeowners call us most often for cooling repairs in peak summer, heating repairs during cold snaps, and full system replacements when age or efficiency makes repair impractical. Each service has its own dedicated Florence page with detailed pricing and local conditions.
AC Repair in Florence
AC repair in Florence means working on systems that have been running at maximum load since May. We see compressor failures, refrigerant leaks in linesets exposed to hard freeze-thaw cycles, and capacitors cooked by sustained high-ambient operation. In older slab homes, we always check the plenum connection first; that kinked flex duct explains more “my AC runs but won’t cool” calls than equipment failure. Our technicians carry common parts for Rheem, York, Daikin, Bryant, and other major brands to complete most repairs in a single visit. AC Repair in Florence

Furnace Repair in Florence
Furnace repair here is often propane furnace repair, and that difference matters. Propane-fired units need different pressure settings, orifice sizes, and combustion analysis than natural gas equipment. After Uri, we also see more heat-pump auxiliary heat failures and cracked condensate lines in unconditioned spaces. We stock igniters, flame sensors, and control boards for the brands Florence homes actually have installed, and we test every repair with a written combustion analysis when propane is involved.

AC Installation in Florence
AC installation in Florence requires load calculations that account for the real envelope of rural homes, not suburban tract templates. Older farmhouses need ductwork evaluation; manufactured homes have chassis constraints; new construction needs proper sizing for 100-degree design days. We specify equipment with low-ambient controls for freeze protection, size propane conversions precisely, and deliver a written fixed price before any work begins. Installations are scheduled, not same-day, with a set date and full rebate paperwork handled. AC Installation in Florence

What Florence Customers Say
"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"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
