We’re Fireside Heating & Air Co. of Houston, and we’ve been serving Fort Bend County homeowners since 2018.

Most calls from Greatwood reach us in under 45 minutes during emergencies. Call (833) 313-7291 anytime - a live person answers, 24 hours a day, including holidays.
Why Fireside Heating & Air Co. of Houston Is Greatwood’s Preferred Emergency & Commercial HVAC Company
Greatwood isn’t a generic suburb to us. We’ve worked in these homes since the first phases were wrapping up in the early 1990s. We know the original Carrier and Trane builder-grade systems that came with the late-1980s and 1990s construction. We’ve seen what Hurricane Harvey did to the ground-level equipment here in 2017. And we’ve made the late-night drives down FM 762 and Grand Parkway enough times to know which turns to take without GPS.
Our reputation in Greatwood is built on showing up when we say we will and fixing it right - backed by our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.
When you call (833) 313-7291, you reach a live person, not a voicemail tree. Nights, weekends, holidays. That matters when your system locks out at 2 a.m. and the house is climbing past 85 degrees.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They treat your home the way they’d treat their mother’s. That’s not a slogan. It’s how we work.
Our Emergency & Commercial HVAC Services in Greatwood
24/7 Emergency HVAC
Greatwood’s cooling season runs roughly eight months, and when a system fails in August, it’s not uncomfortable - it’s unlivable. We answer emergency calls around the clock. A live person picks up, dispatches a technician, and gives you an honest ETA. Most Greatwood emergencies involve one of three failures: a post-Harvey mismatched condenser short-cycling into lockout, an R-22 system that can no longer be legally recharged, or separated attic ductwork dumping cooled air into a 140-degree attic space. We carry parts for Carrier, Trane, Lennox, and Goodman on our trucks, so most repairs finish in a single visit.

Commercial HVAC
Greatwood’s commercial footprint along Highway 90 and near the Grand Parkway corridor includes medical offices, retail strips, and small professional buildings that can’t afford downtime. Our Emergency & Commercial HVAC team handles rooftop units, split systems, and packaged equipment for businesses that need fast turnaround without disrupting customers. We offer upfront pricing on every commercial job - the price quoted is the price paid. No change orders, no surprises.

Rooftop Unit Service
Commercial buildings throughout the Greatwood area rely on rooftop package units for both heating and cooling. These systems take a beating from Houston’s humidity and UV exposure. We service all major brands, perform seasonal inspections, and replace failed compressors, economizers, and control boards. Because we stock common parts locally, Greatwood businesses don’t wait days for a coil or a contactor to ship from Dallas.

Chiller Service
For larger commercial facilities near Greatwood with chilled-water systems, we provide chiller diagnostics, refrigerant recovery, tube cleaning, and control calibration. Chiller failures can idle an entire building. Our technicians are trained to isolate the problem quickly and present repair versus replacement options with straight numbers.

Annual Maintenance & HVAC Inspection
Given Greatwood’s housing stock - mostly 20-35 year old systems in unconditioned attics - an annual inspection isn’t optional if you want to avoid a mid-July emergency call. Our $89 Seasonal Tune-Up includes refrigerant level check, electrical connection inspection, capacitor testing, ductwork visual assessment, and thermostat calibration. We catch the cracked heat exchangers, failing contactors, and refrigerant leaks before they become 2 a.m. emergencies. For commercial clients, we build custom maintenance agreements that fit your equipment schedule and occupancy hours.

Trusted Brands We Service in Greatwood
We’re trained and equipped to service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Greatwood homeowners, this means we don’t have to special-order a control board for your 1998 Lennox or a coil for your 2002 Carrier. We carry common parts on our trucks. When your system fails on a Saturday afternoon, that stock translates to same-day repair instead of sweating through Sunday waiting for a Monday delivery.
Common Emergency & Commercial HVAC Problems We See in Greatwood Homes
- Mismatched post-Harvey condensers causing compressor short-cycling. After 2017, many Greatwood homeowners replaced only the flooded outdoor unit with a high-efficiency condenser, leaving the original 1990s air handler and coil in place. The mismatch restricts airflow, overworks the compressor, and triggers emergency lockouts - usually on the hottest day of the year.
- Attic duct separation from black clay soil foundation movement. Fort Bend County’s expansive soils shift constantly, pulling flexible duct connections apart in unconditioned attics. Conditioned air leaks into 130-140°F attic space, the system runs continuously, and the coil eventually freezes solid.
- R-22 system failure with no legal recharge option. Most original Greatwood systems use R-22 refrigerant, which the EPA banned from new production. When these systems leak, reclaimed R-22 is scarce and prohibitively expensive. Full system replacement is the only practical path.
- Undersized dehumidification in an 80% humidity climate. Greatwood’s latent cooling load rivals its sensible heat load. Aging or improperly matched systems can’t pull enough moisture from the air, leaving homes cold but clammy - a comfort problem that standard temperature settings won’t fix.
Pricing for Emergency & Commercial HVAC in Greatwood, TX
We believe in upfront pricing. The number we quote is the number you pay. No add-ons, no bait-and-switch.

Emergency service calls in Greatwood carry no after-hours premium - we don’t penalize you for calling at 10 p.m. versus 10 a.m. What drives cost is the repair itself: a failed capacitor runs toward the lower end, while a compressor replacement or full refrigerant recovery pushes higher. System replacement costs depend on tonnage, ductwork condition, and whether we’re correcting a post-Harvey mismatch with properly matched equipment.
We offer $50 off any repair over $250, free second opinions on any written estimate, and a permanent 5% discount for seniors and veterans. Call (833) 313-7291 for a free, no-pressure estimate.
Greatwood’s Unique HVAC Challenge: The Post-Harvey Mismatch
Here’s something you won’t find on a generic HVAC page: Greatwood’s master-planned community was built in concentrated phases from the late 1980s through the early 2000s. That means the bulk of its housing stock is now hitting the 20-30 year replacement window simultaneously. Then Hurricane Harvey came through in 2017. The Brazos River corridor flooding damaged many ground-level condensing units throughout the community. Insurance covered outdoor unit replacement, but not the attic air handler and ductwork. So technicians now routinely encounter a configuration almost unique to Greatwood and similar Harvey-impacted master-planned communities: a shiny new high-efficiency condenser paired with a 1990s-era air handler, original evaporator coil, and deteriorating flex duct.
This mismatch underperforms. It fails prematurely. And it generates callbacks that don’t resolve until the full system is replaced with matched components.
We responded to an emergency call in the Quail Run neighborhood where a homeowner’s 1990s Carrier air handler froze solid because a Harvey-replaced high-efficiency condenser was paired with the original coil, restricting airflow. We replaced both units with a matched Trane system and sealed the attic ductwork, ending years of intermittent failures.
If your outdoor unit was replaced after 2017 but your attic equipment wasn’t, you’re likely running a mismatched system. The symptoms are subtle at first: longer run times, higher humidity, uneven cooling between floors. Then the emergency lockouts start.

FAQs - Emergency & Commercial HVAC in Greatwood
Greatwood’s eight-month cooling season pushes aging systems past their design limits, and the 20-30 year old housing stock means most equipment is operating on borrowed time. The combination of 130-140°F attic temperatures, black clay soil foundation movement separating ducts, and post-Harvey mismatched condensers creates failure points that peak under July and August load. If your system is struggling now, it won’t improve - call (833) 313-7291 for a free inspection before it becomes a midnight emergency.
No. The EPA banned production of new R-22 in 2020, and reclaimed supplies are scarce and extremely expensive. Most Greatwood homes built before 2005 have R-22 systems. When they leak, a recharge is rarely cost-effective compared to replacing with a modern R-410A or R-32 system. We offer free second opinions on any replacement estimate you’ve received, and our $89 tune-up can assess whether your system is worth limping through another season.
Yes. We service rooftop units, chillers, and split systems for commercial clients along Highway 90 and the Grand Parkway corridor. Our commercial work uses the same upfront pricing and 90-Day Done Right Promise as our residential jobs. Call (833) 313-7291 to schedule a commercial inspection or discuss a maintenance agreement.
The warning signs are longer run times, cold but clammy air, uneven temperatures between floors, and frequent service calls that never quite fix the problem. If your outdoor condenser was replaced after 2017 but your attic air handler is original to the house, you almost certainly have a mismatch. We can confirm this with a pressure and temperature analysis during a service call. Replacing both units with matched equipment typically cuts utility bills and eliminates the intermittent failures.
Most emergency AC repairs in Greatwood fall between $150 and $650, depending on the failed component. A capacitor or contactor replacement runs toward the lower end. A compressor replacement or major refrigerant leak repair pushes higher. We charge no after-hours premium for emergency calls, and we offer $50 off any repair over $250.
