The process starts with a site assessment and Manual J load calculation. That calculation accounts for your home’s square footage, insulation, window area, and ceiling height, not a rule-of-thumb estimate. Older Denver homes often have ductwork that needs inspection before a new system can perform correctly, so duct condition is reviewed at the same visit.
Once sizing is confirmed, a licensed technician installs the outdoor condenser, indoor evaporator coil, and refrigerant line set. If the air handler or return vents need modification to match the new system’s airflow requirements, that work is scoped and included in the written estimate before scheduling begins.
Startup testing covers refrigerant pressure, airflow at each register, and thermostat calibration. The job is not closed until the system reaches its specified output. Denver’s semi-arid, high-altitude climate means altitude-adjusted sizing is standard, a unit rated for sea level will underperform here without that correction.

Business-level assurance that the job is scoped, priced, and verified correctly from the first call to the final check.
Itemized Written Estimate Before Scheduling
Equipment, labor, ductwork changes, and timeline are all listed before any work is booked, no line items added after the visit.
System Evaluation on Every Enquiry
Every request starts with a load assessment and a review of existing equipment condition before a price is given.
Licensed Local Technicians
We connect you with licensed technicians who work in Denver and know the altitude-sizing requirements for this market.
Post-Install Performance Check
Refrigerant pressure and register airflow are verified after installation so the system performs to its rated specification.
Scope Confirmed Before Equipment Is Ordered
Ductwork modifications and electrical needs are identified at the assessment, not discovered mid-install and added to the bill.
Questions homeowners ask before booking an install
Why does Denver’s altitude affect AC sizing?
At 5,280 feet, air is less dense, so a unit rated at sea level moves less heat than its nameplate suggests. A Manual J calculation corrected for altitude accounts for this. Skipping that step typically results in a system that runs continuously on hot days and still can’t reach the set temperature.
Do I need a permit to install a new AC in Denver?
Yes. Denver and most surrounding municipalities require a mechanical permit for new AC installations. We identify the specific permit needed for your address and handle the application as part of the job scope. An unpermitted installation can create problems at resale and may void the equipment warranty.
What happens if I delay replacing an aging AC unit?
An undersized or failing unit running through a Colorado summer puts increasing strain on the compressor. Compressor failure typically costs more to repair than a planned replacement, and you lose cooling mid-season when demand on installers is highest and lead times are longest.
How long does a residential AC installation take?
A standard central AC replacement typically takes one day once permits are in hand. New construction or installations requiring significant ductwork modifications take longer. Your written estimate will include a timeline specific to your job before anything is scheduled.
What does the post-install check actually confirm?
The technician measures supply and return airflow at each register, verifies refrigerant charge against manufacturer spec, and calibrates the thermostat. If any reading falls outside the acceptable range, it is corrected before the job is closed. You receive a written record of the results.
Can I install a mini-split instead of a central system?
Yes. Ductless mini-splits are a practical option for homes without existing ductwork, room additions, or spaces where extending ducts is not cost-effective. The same altitude-adjusted sizing process applies, and permits are still required for the refrigerant and electrical work.
Describe your home and we will arrange a licensed local technician to assess the system, confirm sizing, and give you an itemized estimate before anything is scheduled.
