HVAC in Castle Hills, Honest AC, Heating, and Indoor Air Quality for the 78213
Tier 1 dispatch into Castle Hills: mid-century-modern retrofit expertise, original ductwork inspection on every quote.
Castle Hills is one of the established inner-loop pockets Above & Beyond services every week: a small independent city, just over a square mile, completely surrounded by San Antonio and bordered by Olmos Park, Shavano Park, and the West Avenue and Lockhill-Selma corridor. The housing stock skews to 1950s to 1970s slab-on-grade ranch homes with mature canopy live oaks, an older established demographic, and a meaningful share of pre-1978 homes where lead-safe work practices apply. The first central-air retrofits went in here in the 1970s; the second-generation replacements went in around 2000 and are now at the end of their service life.
Tommy Coffey, our general manager, opened Above & Beyond in 2019 after 30 years in the trade. Castle Hills is well inside our 20-mile primary service radius: the same dispatch corridor we run for Olmos Park, Alamo Heights, and Shavano Park. No travel surcharge, and the technician who answers the diagnostic is the one who returns to do the repair.
Why Castle Hills Homes Ask More of Their HVAC Contractor
Castle Hills was incorporated in 1951 and most residential homes went up between the mid-1950s and early 1970s. A typical home is a 1,800-to-2,800-square-foot single-story brick or stucco ranch built before central air was standard. The original HVAC was a window-unit array or a small attic-mounted system added in the 1970s, with ductwork routed through whatever attic space or closet chase was available. Forty-plus years later, return-air runs are routinely undersized for the system now connected to them. We run a static-pressure test on every Castle Hills diagnostic so we can tell you whether the system itself is failing or the ductwork is choking it.
The second-generation replacements installed around 2000 used R-22 refrigerant, phased out in 2020. Reclaimed R-22 has become much more expensive, so the math on a refrigerant-leak repair on a 20-plus-year-old system swings toward replacement faster than it does on newer R-410A or R-454B equipment. We put the honest numbers on paper: repair quote alongside replacement quote. We never use the phrase 'you have to replace.' A meaningful share of homes here also predate 1978, so when we cut into walls or open access panels we follow EPA Renovation, Repair, and Painting practices: containment, HEPA vacuuming, dust-safe cleanup.
Services We Provide in Castle Hills
AC, Heating, and Indoor Air Quality
The three most common AC repairs we run in 78213 are refrigerant leak repairs, dirty-system clean-and-restore, and capacitor replacements. Capacitor replacements run $150-$350; refrigerant leak repairs $200-$1,400. The three most common heating failures are fan motor, hot surface ignitor, and circuit board; furnace repairs typically run $300-$600. SA has three allergy seasons (cedar fever late December through February, live oak pollen March through early May, and ragweed late August through October), and older Castle Hills duct boots let allergens recirculate. We install whole-home air purifiers ($1,000), whole-home dehumidifiers ($4,000), Aprilaire and REME Halo units, and UV-light kits.
Installation, Ducts, and the Maintenance Plan
A typical Castle Hills install is a 2.5-to-4-ton residential system. Default install is single-stage equipment. New AC plus furnace installations qualify for 0% financing through Wells Fargo (72-month special), FTL Finance, or AC Credit Services. Whole-home duct sealing runs $1,500-$4,000; full duct replacement runs $3,000-$5,000. The $159 Maintenance Plan covers two visits a year (spring AC tune-up plus fall heating tune-up), priority dispatch, no after-hours surcharge, and 10% off repairs.

Frequently Asked Questions
Do you charge extra to dispatch to Castle Hills?
No. Castle Hills sits well inside our 20-mile primary service radius, minutes away on the inner Loop 410 NW corridor. There is no travel surcharge on any standard service call.
What is your response time for a Castle Hills emergency call?
1 to 2 hours for AC emergencies and 2 to 4 hours for heating during standard hours. After-hours calls reach a working Above & Beyond technician at (210) 837-1466. The after-hours premium is $129 and is waived for heat-vulnerable households.
My home is from the 1960s and the AC still uses R-22. Is repair worth it?
Depends on the failure mode and how much refrigerant is involved. Reclaimed R-22 has become much more expensive since 2020, so the math swings toward replacement faster on R-22 systems. We give you the honest numbers on paper: the repair quote and a replacement quote. You decide.
My back bedroom never gets cool. Is the system failing?
Often no. The system is healthy and the ductwork is choking it. Original return-air runs in a 1950s or 1960s Castle Hills ranch are routinely undersized for the system that has been connected to them since the last replacement. We run a static-pressure test on every diagnostic in this housing stock.
I am 65-plus. Do you offer a senior discount, and what is the repair warranty?
Yes. 10% off for customers 55 and older on both repairs and installations, applied automatically. Repair warranty is a 30-day callback plus a 90-day general repair warranty. New-install workmanship is 1 year and parts are 10 to 12 years registered. Financing runs through Wells Fargo, FTL Finance, and AC Credit Services.
