Somerset isn’t like the neighborhoods 20 miles north. Most addresses here sit beyond Atmos Energy’s natural gas mains, so a “standard” AC installation is rarely standard. We’re talking heat pumps paired with propane backup, electrical panels that need upgrading before a modern system can draw what it needs, and ductwork in manufactured homes that’s been baking in attics since the 1990s. Our technicians know the difference between a tract home off FM 476 and a 1980s double-wide on a rural lot, and they size the system accordingly.
Why Coldharbour Heating & Air Is Somerset’s Preferred AC Installation Company
We’ve been part of the Kingswell network since 2003, and our independently owned operation has built a reputation in Somerset by showing up in the window we promised and leaving the price in writing before the first tool comes out. Homeowners here tell us the same story: the last company quoted one price on the phone, then added “surprises” at the door. That doesn’t happen with us. The price you sign is the price you pay.
Our response time to Somerset is typically same-day or next-day for estimates, with installation scheduled once you’ve approved the written quote. We know the local terrain, from the newer subdivisions pushing south from San Antonio to the manufactured home communities along US 281 where package units sit on rooftops and flex duct runs through crawlspaces that haven’t been opened in decades.
Every technician is background-checked, uniformed, and trained on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. When we pull up to your Somerset home, we’re prepared for whatever system is there and whatever condition it’s in.
Furnace Installation in Somerset
Furnace Installation in Somerset means something different than it does inside San Antonio city limits. Because no natural gas mains reach most Somerset addresses, we’re typically installing a propane-fired furnace paired with a heat pump, not the gas furnace swap a north-side crew would quote. The furnace connects to your existing 250-500 gallon propane tank, with the heat pump handling cooling and mild-weather heating, and the propane furnace kicking in only when temperatures drop below the heat pump’s efficient range.
A complete furnace installation here falls within our $3,500-$7,500 system range, depending on whether we’re matching to existing ductwork or rebuilding it. Most Somerset homeowners who need furnace installation are either replacing an aging propane unit that failed in a freeze, or converting from electric resistance heat to a more efficient dual-fuel setup.
Propane Tank Integration and Sizing
Your propane tank size dictates how long you can run in backup mode before a refill. A 250-gallon tank in a hard freeze empties fast if the heat pump isn’t carrying the load. We size the furnace to work with your existing tank, and we explain exactly when the switchover happens so you’re not caught short.
Auxiliary Heat Strips for Extreme Cold
Winter Storm Uri taught Somerset homeowners a hard lesson about heat pumps without backup. We install auxiliary heat strips on every heat pump we put in, and we wire them so they engage automatically when the propane furnace can’t keep up or the tank runs low. It’s not optional here. It’s survival.
HVAC Installation in Somerset
HVAC Installation in Somerset covers the full system: outdoor condenser or heat pump, indoor air handler or furnace, ductwork, thermostat, and electrical connections. For a typical Somerset home, this runs $3,500-$7,500, with the final price depending on whether we’re working with existing ductwork or rebuilding from the plenum out. Most jobs take one to two days, with the system operational by the end of day one if the electrical panel and ductwork are ready.
We start every HVAC installation with a Manual J load calculation, measuring your home’s heat gain and loss rather than guessing based on square footage. In Somerset’s manufactured homes with their thin walls and single-pane windows, that calculation often reveals the original system was undersized or, more commonly, the ductwork was so poorly sealed that no amount of tonnage could cool the back bedrooms.
Electrical Panel Upgrades
A modern heat pump can draw 30-50 amps on startup. Many Somerset homes, especially older manufactured units, still have 100-amp panels that are already maxed out with window units, well pumps, and outbuildings. We check your panel during the estimate, and if it needs upgrading, we tell you then, not when the installer is standing in your kitchen with the old unit already disconnected.
Ductwork Rebuilds for Manufactured Homes
On a job off FM 476 we pulled a 1990s manufactured home’s rooftop package unit and found the original flex duct crushed to about half its cross-section in the crawlspace, so a like-for-like 3-ton swap would have choked on static pressure before it ever cooled the back bedroom. We ran a load calculation, upsized to a 3.5-ton Carrier heat pump with a propane-fired backup furnace to match the existing tank, and rebuilt the trunk line with hard duct to get the bedrooms balanced. The homeowner’s summer electric bill dropped, and the system actually held temperature through the first August heat wave.
Trusted Brands We Service in Somerset
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Somerset customers, we keep common parts stocked locally for Rheem, York, and Daikin systems, which means faster turnaround when a capacitor or contactor fails in July. We don’t push one brand over another. We match the equipment to your home’s ductwork, your electrical service, and your propane setup, then we give you written options at different price points so you can decide what fits your budget.
Common AC Installation Problems We See in Somerset Homes
- Like-for-like tonnage swaps in aging manufactured homes. The original flex duct is deteriorated and undersized, so a new condenser can’t overcome the static pressure. The back rooms never cool, the compressor runs constantly, and the homeowner blames the new unit when it’s the ductwork that failed.
- Installing a modern heat pump without addressing the electrical panel or adding auxiliary heat strips. This setup failed hard during Winter Storm Uri. The heat pump locks out in low temperatures, there’s no backup, and the house goes cold while you’re waiting for a propane delivery that can’t come fast enough.
- Skipping a load calculation on a tight single-zone floor plan. The new system short-cycles, never fully dehumidifies Gulf-moisture air, and the oversized tonnage wears the compressor early. We’ve replaced five-year-old compressors in Somerset because the original installer guessed at the size.
- Ignoring Somerset’s hard-water and high-dust conditions. Rural well water and caliche dust accelerate coil corrosion and clog condensate drains. We spec coated coils and accessible drain cleanouts on every install here.

Every estimate is free, and every price is fixed before work begins. That’s The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails.

FAQs About AC Installation in Somerset
Because the original flex duct is probably deteriorated and crushed, so a new unit of the same tonnage will choke on static pressure and never cool the back rooms. We measure airflow, run a load calculation, and often upsize the unit while rebuilding the ductwork with hard pipe. Call (817) 402-2972 for a free estimate.
We install heat pumps with propane backup furnaces, not natural gas furnaces, because most Somerset addresses aren’t served by gas mains. Your existing propane tank fuels the backup furnace, and the heat pump handles cooling and mild-weather heating. Call (817) 402-2972 to discuss your setup.
Maybe not. Many Somerset manufactured homes have 100-amp panels that are already maxed out. We check your panel during the free estimate and tell you upfront if an upgrade is needed, with the cost in writing before any work begins. Call (817) 402-2972 to schedule.
We recommend 15-17 SEER2 for most Somerset homes. Higher ratings exist, but the payback period stretches out in our climate, and the more complex electronics can struggle with rural power fluctuations. We give you written options so you can choose. Call (817) 402-2972 for specifics on your home.
Every heat pump we install gets auxiliary heat strips wired for automatic engagement, and we size the propane backup furnace to carry the full heating load if the heat pump locks out. We also verify your propane tank size and discuss refill timing so you’re not caught short. Call (817) 402-2972 to talk through your freeze protection.
