Air Conditioner Installationin Golden & Denver Metro
The right air conditioning system, properly installed, keeps your home comfortable for 15 to 20 years while keeping energy costs under control. A1 Choice Heating & A/C sizes and installs residential AC systems with the expertise and attention to detail that only 30+ years of Colorado experience provides.
Why Proper Sizing Matters
The single most important factor in AC installation is getting the size right. An oversized air conditioner cools your home too quickly, cycling on and off rapidly without properly removing humidity. This creates a clammy, uncomfortable environment and wears out components faster. An undersized unit runs constantly during hot days, struggling to keep up and driving up your electricity bill.
At A1 Choice, we never guess on sizing. We perform a detailed cooling load calculation that considers your home’s square footage, ceiling height, insulation quality, window size and orientation, number of occupants, and the specific elevation of your neighborhood. Colorado’s altitude affects air density, which directly impacts how much cooling capacity your system needs.
This methodical approach ensures that your new air conditioner runs at peak efficiency from day one, maintaining consistent comfort while keeping your energy costs as low as possible. It is the difference between a system that works for you and one that works against you.
Our Installation Process
Our AC installation process begins with a thorough in-home assessment. We evaluate your current system, inspect ductwork condition, check electrical capacity, and identify the optimal placement for the new outdoor condenser unit. We then present our recommendation with complete pricing — no hidden fees, no surprises.
On installation day, we start by protecting your home. We lay drop cloths, wear shoe covers, and clean up completely when we are done. We remove the old equipment, install the new condenser on a proper mounting pad, run and braze refrigerant lines, connect electrical wiring, and integrate the system with your thermostat.
Testing is where our experience really shows. We verify refrigerant charge using subcooling and superheat measurements rather than just pressure readings. We test temperature split across the evaporator, check static pressure in the ductwork, and confirm that every safety control functions properly. This level of verification ensures maximum performance and longevity from your new system.

Common Questions
AC Installation FAQs
What size air conditioner does my home need?
We perform a cooling load calculation that accounts for your home square footage, insulation, window orientation, number of occupants, and Colorado altitude. This ensures the unit is sized correctly for efficient, even cooling.
How long does AC installation take?
A standard residential AC installation typically takes one day. This includes removing the old outdoor unit, setting the new condenser, connecting refrigerant lines, testing the system, and verifying proper operation.
What SEER rating should I look for?
Current minimum efficiency standards require at least 14 SEER for Colorado. We typically recommend 16 SEER or higher for the best balance of upfront cost and long-term energy savings. Higher SEER units also tend to run quieter.
Do you offer any discounts on AC installation?
Yes. We currently offer $500 off a furnace when installed at the same time as a new air conditioner. This bundle saves on labor costs and ensures both systems are perfectly matched.
Will a new AC lower my energy bills?
If you are replacing an older, less efficient unit, yes. A modern 16 SEER system uses significantly less electricity than an older 10-12 SEER unit. Most homeowners see a noticeable drop in summer electric bills after upgrading.
