Air Conditioning Installation Questions

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.

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.

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.

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.

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.

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.
