Air Conditioning and Evaporative Coolers: What Colorado Buyers Should Know

By David Parks · eXp Realty · The Apollo Group · 2 min read

The Short Answer

Many Colorado homes use central air conditioning, while others rely on evaporative (swamp) coolers or have no cooling at all. An inspection checks that the system runs, cools properly, and is in serviceable condition.

How each system works

Central air conditioners use refrigerant to remove heat and moisture. Evaporative coolers pull dry air through wet pads, which works best in low-humidity climates like Colorado’s but cools less on humid days.

What inspectors check

Quick Poll

Have you ever dealt with a cooling problem (AC or evaporative cooler)?

Things to be aware of

Older units may use refrigerants that have been phased out, which can make repairs costly. Condensers often last around 15 years. Inspections are best done when outside temperatures allow testing, and in winter an inspector may not be able to run AC safely.

What to ask

Ask when the system was last serviced, whether ductwork reaches all rooms, and whether the home has a way to cool upper floors. If a home lacks AC, price in the cost of adding it if that matters to you.
