Montrose asks less of an air conditioner, but it still has to hold up

Cooling season here runs July and August, about two months a year. Summer afternoons average 83°F, which is mild compared to a lot of the country, so a new system isn't fighting extreme heat for months on end.

What it does have to handle is weather. Montrose County has logged 53 damaging wind events and 4 hail events over the past ten years, with hail up to 1.5 inches recorded. An outdoor condenser sits outside through all of that, so the cabinet and coil fins need to be able to take a hit. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

What size air conditioner does my house need?
The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor looks at your insulation, your windows, how many rooms you have, and which way your house faces before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. Since Montrose only needs cooling in July and August, getting the size right matters more for comfort during those two months than for running costs spread over a long season.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or different efficiency ratings, replacing just the outdoor unit usually is not a good match. The two are engineered to work as a pair, and mixing an old coil with a new condenser can mean the system never reaches the efficiency it is rated for, sometimes voiding the warranty too. A contractor can check whether your existing coil and refrigerant lines are compatible with a new outdoor unit before you decide. If both parts are old, replacing them together is generally the safer route.
Do HVAC contractors in Montrose need a state license to work on my home?
Yes, anyone installing or repairing a central air conditioning system in your home needs a state contractor license. Ask to see the license number before work starts, and check that it is active. A licensed contractor also carries the insurance that protects you if something goes wrong during the installation.
