The programme
Comfort designed room by room, not unit by unit
Every McAllen home we take on gets a room-by-room load study, because a single thermostat cannot fix a house the sun hits from three sides.
Zoned comfort design
Motorised zoning and bypass-free static control so the west bedrooms stop lagging the thermostat by four degrees.
Zone the housePackage unit replacement
Rooftop swaps with new curb adapters, sealed transitions and crane scheduling handled for you.
Replace a package unitDuct renovation
Aerosol sealing, correctly sized returns and insulated attic runs that survive 160-degree attics.
Renovate duct workIndoor air quality
Media filtration, fresh-air management and humidity control tuned for rainstorm season.
Improve air qualityConcierge maintenance
Three visits a year, refrigerant and electrical trending, and named-technician continuity.

How we work
Five steps to designed comfort
Comfort survey
We walk every room, log temperatures and ask which spaces you actually avoid in August.
Room-by-room study
A load calculation per room, plus static pressure on the existing duct work, before any equipment is named.
Design presentation
One page per option: capacity, sound level, staging behaviour, rebates and the real annual cost.
Installation
Protected floors, crane and permit scheduling handled, and a named lead technician on site all day.
Commissioning
Airflow and charge verified, a printed report, and a return visit inside the first cooling season.
Who you work with
A small premium shop with named technicians
The crew behind Air System Experts Air Conditioning & Heating Service around a simple promise: the same technician who designs your system is the one who commissions it and the one who returns for maintenance. That means fewer jobs per year in McAllen, longer appointments, and a level of documentation most homeowners never see — room loads, static pressure and refrigerant trending, all kept in your file. If the house is not comfortable, the design is not finished.

What homeowners say
★★★★★
The west bedrooms used to run four degrees hot. After zoning and a proper return, they are within one of the thermostat.

Same technician three visits running. He knew the system without reading the file.

Quiet enough that we stopped noticing the system, which after our old one is the highest compliment I have.

Before you commit
Straight answers on designed comfort
Why a room-by-room load study?
Because a whole-house number cannot tell you which rooms are starved. The per-room study is what makes zoning decisions honest.
Is variable-capacity worth it here?
In TX heat, usually yes: longer run times at low capacity dehumidify better and cost less than repeated full-speed cycling.
What does the maintenance programme include?
Three visits a year, priority response, refrigerant and electrical trending, and a named technician who knows your system.
Do you handle HOA and permits?
Yes. We submit equipment locations and screening details to your HOA and pull McAllen permits before scheduling the crane.
How far out is installation?
Typically one to two weeks outside peak season, and we keep emergency cooling available for members in the meantime.
