HVAC Company in Alvarado, TX
Most HVAC calls in Alvarado fall between $150 and $700 for repairs, with new AC installations running $3,500-$7,500 depending on the home. What drives the price isn’t just the equipment, it’s the unusual mix of housing vintages here, from 1970s ranch homes with original R-22 systems to manufactured homes with belly-wrap ductwork that suburban crews rarely see. We’re Coldharbour Heating & Air, and our technicians train on all of it, including the package units and under-floor systems common in the rural areas around Johnson County. Call us at (817) 402-2972 for a free estimate, or keep reading to see how Alvarado’s specific conditions affect the work we do.
Why Alvarado Homes Are Different
Alvarado sits at the southern edge of the DFW growth wave along I-35W, and that location creates a housing landscape you won’t find in a typical suburb. The original town core holds aging slab-on-grade ranch homes built from the 1970s through the 1990s, many still running original or once-replaced equipment with ductwork that was barely adequate when it was new. Step outside the city limits and you’re in manufactured-home country, where HUD-code homes with belly-duct configurations and package units make up a significant share of the housing stock.
The climate here doesn’t forgive marginal systems. Summer temperatures regularly push past 100°F with humidity that drives heat-index values even higher, while winter ice storms on I-35W can knock out power and freeze exposed refrigerant lines on outdoor package units. Then there’s the black expansive clay soil Johnson County is known for, slab movement from that clay shifts floor registers and disconnects flex-duct connections over time. What looks like a system failure is often a duct-integrity problem, and telling the difference saves homeowners from replacing equipment that isn’t actually broken.
Manufactured-home belly-duct repairs are a routine call for us and a mystery to many suburban-focused contractors. When the insulated wrap underneath tears or sags from moisture or animal intrusion, cooling loss is dramatic. Fixing it means crawling through Johnson County clay, not pulling an attic hatch. Our technicians carry the materials and know the assembly methods these homes require.
Our Main Alvarado Services
Alvarado homeowners call us most often for cooling repairs in July and heating repairs in January, but the full range of what we handle here reflects the area’s housing diversity. Each service below has its own detailed page with pricing, common failure modes, and what to expect when we arrive.
AC Repair in Alvarado
Summer in Alvarado means systems running at full capacity for weeks straight, and the stress shows up in predictable patterns. We see a lot of capacitor failures on aging outdoor condensers, refrigerant leaks in corroded copper lines, and compressor strain on systems that were never properly sized for the humidity load. In manufactured homes, we also find crushed or disconnected belly ducts that blow cooled air straight into the crawl space instead of the living area. Our technician will test the full system, not just the obvious symptom, and hand you a written price before any work begins. AC Repair in Alvarado

Furnace Repair in Alvarado
Winter furnace calls here split between ignition failures on older gas furnaces in the in-town ranch homes and heat-strip or sequencer problems on electric package units common in manufactured housing. The freeze-thaw cycle on outdoor package units can crack heat exchanger seams or damage control boards if water gets in. We carry igniters, flame sensors, and control boards for the major brands, and we’ll check gas pressure or amperage draw to confirm the repair is complete before we leave. Furnace Repair in Alvarado

AC Installation in Alvarado
New system sizing in Alvarado requires understanding which house type we’re working with. Older ranch homes often need ductwork upgrades to handle modern SEER2 equipment airflow requirements, while manufactured homes may need package-unit replacements with specific clearances and tie-downs. New construction on the south side of town brings its own load-calculation requirements as building envelopes tighten. We perform a full Manual J load calculation, provide a fixed written price, and schedule installation for a specific date, parts ordered and ready. AC Installation in Alvarado

What Alvarado Customers Say
"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly"Furnace wouldn't light the first cold morning. The guy walked me through what he was checking so I actually understood it. Replaced the igniter, wrote up the warranty, and it's been warm since."
- Alicia Romero"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."
