AfterFast, Reliable AC Installation Across Redwood
AC installation in Redwood, TX typically costs $3,500-$7,500 for a complete system, and most installations are scheduled within 3-5 business days after your free in-home estimate. We’re Coldharbour Heating & Air, and our AC Installation team has been sizing and installing systems for rural Gonzales County properties since 2003. Dispatch runs from our Dallas-Fort Worth office, but our crews live in and around the Redwood area, so we know the backroads, the well-water mineral content, and the reality that there’s no municipal gas line to rely on. Call (817) 402-2972 for a free written estimate, and we’ll give you a firm price before any work begins.
Redwood sits on the edge of the Texas Hill Country transition, where summer heat indices push past 105°F and winter can dip hard enough to test any heating system. That wide swing, combined with exposed rural lots and housing stock that runs heavy toward older ranch-style homes and manufactured units, means cookie-cutter sizing doesn’t work here. We do a room-by-room load calculation on every job, because a system that’s “close enough” for a shaded suburban lot in Seguin will fail you on an open Redwood property with no windbreak.
Why Coldharbour Heating & Air Is Redwood’s Preferred AC Installation Company
We’re independently owned and operated under the Kingswell network, which means we follow The Kingswell Way: say the price before the work starts, show up in the window promised, leave the place cleaner than we found it, put every guarantee in writing, and come back if it fails. Homeowners in Redwood tell us they’ve dealt with contractors who sized by square footage and disappeared. We don’t do that. Every installation gets a written load calculation, a written fixed price, and a written 365-Day Done Right Promise.
Our technicians are background-checked, uniformed, and trained on nine major brands including Rheem, York, and Daikin. When you call (817) 402-2972, a live person answers, 24 hours a day, 7 days a week. No voicemail trees. No “call back tomorrow.” We’ve had Redwood customers reach us at 10 PM on a Saturday because their old system died, and we had an estimate on their desk Monday morning.
We know the local conditions: the hard well water that clogs condensate drains, the flex duct in unconditioned attics that collapses after a decade of 140°F summer peaks, the propane tanks that need proper gas pressure set for a new furnace. That local fluency matters when you’re choosing a system that has to last 15 years on a property with no wind shelter and no gas main.
Furnace Installation in Redwood
Furnace Installation in Redwood means working with propane, not natural gas, because this unincorporated Gonzales County community has no municipal gas distribution infrastructure. Most Redwood properties either have an existing propane tank or need one sized and permitted for a new propane-fired furnace. Our job starts with checking your current tank capacity, regulator pressure, and gas line sizing, then matching a furnace to that supply and your home’s heat load. A typical propane furnace installation in Redwood runs $3,500-$7,000, including the combustion safety testing we perform before we leave.
Propane System Compatibility
Propane furnaces burn hotter than natural gas, so the orifice size, gas valve pressure, and combustion air supply all need adjustment. We verify every propane installation with a combustion analysis test on the heat exchanger. Carbon monoxide safety isn’t negotiable, especially in older ranch homes with original venting.
Pairing with Heat Pumps
Many Redwood homeowners run a propane furnace as backup to a cold-climate heat pump. We size the heat pump to carry the load down to its balance point, then set the propane furnace to take over only when temperatures drop below that threshold. Done right, you burn minimal propane. Done wrong, the strip heat runs all January and your electric bill explodes.
HVAC Installation in Redwood
HVAC Installation in Redwood covers the full pairing of cooling and heating equipment for properties that can’t rely on simple gas-furnace-plus-AC setups. Because there’s no natural gas main, we’re typically installing either a straight electric system with a heat pump, or a hybrid propane-and-electric setup. The full HVAC installation process includes load calculation, ductwork assessment, equipment selection, refrigerant charging by subcooling, and combustion testing where propane is involved. In Redwood, a complete HVAC installation generally falls in the $3,500-$7,500 range depending on equipment tier and ductwork condition.
Rural Load Calculation
Exposed rural lots with no tree line or windbreak lose heat faster in winter and gain it faster in summer. We use Manual J load calculations that account for infiltration rates, solar exposure, and the specific orientation of your home. Sizing by square footage alone undersizes winter heat pump capacity on these open properties.
Ductwork in Unconditioned Spaces
Many Redwood homes route flex duct through attics that hit 140°F in July and crawl spaces that drop below freezing in January. We inspect every foot of existing ductwork before quoting a new system. Collapsed or torn flex duct will kill efficiency no matter how good your new condenser is.
Trusted Brands We Service in Redwood
We install and service Rheem, York, and Daikin systems, and we stock common parts for these brands at our Dallas-Fort Worth warehouse for fast turnaround on warranty calls. Rheem’s Classic Plus and Prestige lines offer solid value for propane furnace pairings, with heat exchanger warranties that hold up in rural service. York’s YHE and YFK modulating furnaces work well with variable-speed heat pumps for the hybrid setups many Redwood properties need. Daikin’s FIT heat pumps handle the wide temperature swings of Gonzales County with inverter-driven compressors that don’t cycle on and off in mild weather. We also service Carrier, Trane, Lennox, Goodman, Bryant, and American Standard, so whatever system is already in your home, our technician can work on it.
Common AC Installation Problems We See in Redwood Homes
- Square-footage sizing on exposed rural lots. Contractors who size by square footage instead of doing a load calculation undersize winter heat pump capacity. On an open Redwood property with no windbreak, that means the strip heat runs all January and your electric bill doubles.
- Collapsed flex duct in unconditioned attics and crawl spaces. The housing stock around Redwood includes older manufactured homes and ranch houses with flex duct routed through spaces that see extreme temperature swings. New condensers get blamed for poor cooling when the real problem is torn duct dumping air into the attic.
- Mineral scale from hard well water clogging condensate drains. Redwood properties on private wells have high mineral content. Scale buildup in evaporator pans and condensate lines causes water damage and shutdowns that get misdiagnosed as refrigerant problems by techs unfamiliar with rural water conditions.
- Outbuildings pulling load off the house system. Shop buildings, barns, and detached garages on the same meter often get conditioned by extending ductwork or cranking the main thermostat. That overloads the house system and creates hot spots. We address this with dedicated mini splits sized for each space.

FAQs About AC Installation in Redwood
No, Redwood has no municipal natural gas distribution infrastructure, so natural gas furnaces aren’t an option here. Virtually all heating systems in this area run on propane or electric heat, and we size and install both. Call (817) 402-2972 and we’ll walk through whether a propane furnace, heat pump, or hybrid setup makes sense for your property.
No, we do not charge extra for estimates in Redwood. Your in-home load calculation and written quote are free, with no obligation. We dispatch from our Dallas-Fort Worth office, and rural properties are part of our standard service area.
Yes, mini splits are often the best solution for outbuildings on rural Redwood properties. We size the outdoor condenser to handle the shop’s load independently, so you’re not overworking your house system or running ductwork across the yard. We recently installed a dedicated mini split for a shop off the Gonzales County backroads where the owner was pulling house AC through a window unit.
We perform a room-by-room Manual J load calculation that accounts for your home’s square footage, insulation, window efficiency, solar orientation, and - critically for Redwood - the infiltration rate on an exposed rural lot with no windbreak. Sizing by square footage alone routinely undersizes heat pump capacity for winter heating in these conditions.
For Redwood’s long, hot summers and wide seasonal swings, we typically recommend SEER2 ratings of 15 or higher for split systems, with HSPF2 ratings that matter as much as cooling efficiency because your heat pump will work hard in winter too. Higher SEER2 equipment often qualifies for utility rebates, and we handle that paperwork. Call (817) 402-2972 for a free estimate on qualifying equipment.
