Allen AC Installation Experts
AC Installation in Allen, TX - Armstrong ProTeam Dealer Since 1970
A new central air conditioning system is one of the biggest decisions an Allen homeowner makes - it shapes your comfort, your energy bills, and your home's value for the next 15 to 20 years. Trotter Air Services has been installing central AC systems across North Texas since 1970, and our headquarters at 1111 Jupiter Road in Plano sits roughly 10 to 15 minutes from most Allen neighborhoods. Three generations of the Trotter family have built this business on sizing the system correctly, installing it to factory specification, and standing behind the work.
As an Armstrong ProTeam dealer, we carry one of the most trusted product lines in the HVAC industry and hold the factory training to install it exactly the way the manufacturer intended. Every installation starts with an in-home Manual J load calculation - not a square-footage guess - so the equipment matches your Allen home's actual cooling load.

When Allen Homes Need a New Central AC System
Allen sits north of Plano along US-75, and its housing stock spans roughly four decades of construction - which means we see the full range of replacement situations here. In established neighborhoods built in the late 1980s and 1990s, the original or second-generation systems are aging out: central air conditioners in North Texas typically last 12 to 18 years, and once a system passes the 15-year mark, major repairs become harder to justify financially. Some of these older systems still run R-22 refrigerant, which was phased out of production - servicing them only gets more expensive, and replacement with a modern R-410A system eliminates that cost entirely.
The signals we look for are consistent: repair frequency climbing to three or four visits in two years, electric bills rising each summer without a change in usage, uneven cooling in rooms that used to be comfortable, short-cycling, or a system that has become noticeably louder. Older equipment rated at 10 SEER or below also consumes significantly more electricity than modern 14 to 20 SEER systems - and in a climate where the AC runs heavily from May through October, that difference shows up on every bill. If you are seeing these signs in your Allen home, we will come out, evaluate the system honestly, and tell you whether a repair still makes sense or whether replacement is the smarter investment - and explain our reasoning either way.
Our AC Installation Process for Allen Homeowners
We do not just swap out boxes. Every Allen installation from Trotter Air Services follows the same methodical process we have refined over five decades, so the new system performs at its best from day one.
- In-home load calculation - We measure your Allen home's conditioned space and run an ACCA Manual J load calculation covering insulation, window orientation, ceiling height, and ductwork - not a square-footage rule of thumb.
- Equipment selection - We present options from the Armstrong product line, from reliable standard-efficiency models to premium high-SEER variable-speed systems, explained in plain language with no overselling.
- Professional installation - Removal and disposal of the old equipment with proper refrigerant recovery, then the new condenser, evaporator coil, and line set installed to factory specification with code-compliant electrical and a ductwork evaluation.
- Commissioning and testing - We weigh in the exact refrigerant charge, verify it with superheat and subcooling measurements, confirm airflow matches the manufacturer's CFM specification, and run a complete startup procedure.
- Walk-through and warranty registration - We show you the thermostat and filter schedule, register your warranty with the manufacturer, and leave you the documentation.
AC Installation Cost in Allen, TX
The cost of a central AC installation in Allen depends on the size the load calculation calls for, the SEER rating and feature level you choose, and the condition of your existing ductwork. We do not publish dollar figures here because the right number depends on your specific home - what we provide instead is a written, all-in price after the free in-home load calculation, so there are no surprises. The table below shows how each factor moves the quote.
| Factor | How It Affects Your Quote |
|---|---|
| System Capacity (Tonnage) | Determined by the Manual J load calculation - larger homes and bigger cooling loads need higher-capacity equipment. |
| Efficiency Level (SEER) | Standard-efficiency systems cost less up front; high-SEER variable-speed systems cost more but use less electricity every month from May through October. |
| Ductwork Condition | Ducts in good condition stay in place. Significant leaks, restrictions, or sizing issues call for targeted improvements so the new system can deliver its rated performance. |
| Scope of Replacement | We recommend replacing the outdoor condenser and indoor evaporator coil together - mixing old and new components creates efficiency mismatches and can void warranties. |
| Electrical and Access | Older homes sometimes need electrical upgrades; tight equipment locations add labor time. |
Service Finance financing is available for qualified customers, and many homeowners find the monthly energy savings from a new, efficient system offset a meaningful portion of the payment. We walk through the options during the consultation.

Frequently Asked Questions About AC Installation in Allen, TX
Most residential central AC installations are completed in one day. A straightforward replacement - removing the old unit and installing the new one in the same location with compatible ductwork - typically takes 6 to 10 hours. If ductwork modifications, electrical upgrades, or equipment relocation are needed, the work may extend into a second day. We give you a clear timeline during the consultation.
There is no universal answer based on square footage alone. The correct size depends on your home's insulation, window count and orientation, ceiling height, ductwork configuration, and number of stories. We perform a Manual J load calculation for every installation to determine the exact capacity your home requires. Oversizing is just as problematic as undersizing - an oversized system short-cycles, wastes energy, and fails to properly dehumidify your home.
We strongly recommend replacing the entire system - outdoor condenser and indoor evaporator coil - at the same time. Mixing old and new components creates efficiency mismatches, can void manufacturer warranties, and often leads to premature failure of the older component. The small savings from keeping the old indoor coil are almost always outweighed by the problems it creates down the road.
SEER measures cooling efficiency over an entire season, and it matters more here than in most places because your AC runs heavily from May through October. Current federal standards require 15 SEER for new installations in the southern United States, including Texas. The difference between a 15 SEER and an 18 SEER system can mean meaningful monthly savings on your electric bill. We help you weigh the upfront cost difference against long-term savings based on how long you plan to stay in the home.
Yes. We partner with Service Finance to provide flexible financing options for AC installations. Many homeowners find that the monthly energy savings from a new, efficient system offset a significant portion of the financing payment. We walk you through the options during the consultation so you can make the decision that fits your budget.
