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
Age and condition of the outdoor condenser and indoor coil.
Temperature difference between supply and return air.
Condensate drain lines and signs of leaks.
For evaporative coolers: pads, pump, water lines, and seasonal shutdown.
Quick Poll
Have you ever dealt with a cooling problem (AC or evaporative cooler)?
You are not alone. Get the findings in writing from a licensed professional, keep photos and receipts, and if you are buying, use the report as a negotiation point before your inspection deadline. Talk with David if you want a second opinion on what matters.
Good news, but this is exactly the kind of issue that can stay hidden until someone looks. Add it to your inspection checklist or ask your inspector about it before you buy or sell.
That is very common. The simplest way to know is to have it checked. Ask David which inspections are worth adding for the home you are considering. Talk with David.
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.
