Reviewed by Colton Air Conditioning, NV license 0092120 Desert dust, blowing sand and long cooling seasons are hard on outdoor coils and indoor drains. Homeowners want to know what a spring maintenance visit should actually do before triple-digit heat arrives. Colton's owner answers our questions about getting a system ready, from the outdoor unit to the coils. Related reading: dirty AC coil.
The interview
Q1. What does dust do to an outdoor unit over a Las Vegas year?
Las Vegas dust is relentless. Between desert winds, construction activity, landscaping, and everyday airborne debris, our air conditioning systems deal with conditions that can be harder on equipment than homeowners realize. One of the biggest concerns is restricted airflow. When condenser coils become packed with dirt and debris, the system has a harder time rejecting heat outdoors. That can increase operating pressures, reduce efficiency, and place additional stress on the compressor.
Q2. On a spring visit, what do you check that a homeowner cannot see?
Indoor airflow is equally important. Restricted return ducts and contaminated evaporator coils can reduce airflow and cause poor cooling performance. In severe cases, airflow problems can contribute to evaporator coil freezing. One thing I always emphasize is that maintenance isn't just about cleaning equipment. It's about verifying that the system is actually operating correctly. A clean air conditioner with improper airflow or an electrical problem can still fail when temperatures reach 110°F.
Q3. What should a homeowner watch for between visits?
Before summer arrives, I recommend making sure supply and return vents aren't blocked, and having the equipment inspected. The outdoor condenser should also be kept clear of vegetation, debris, and anything that restricts airflow. Here in Las Vegas, preparation matters because nobody wants to discover a problem during the hottest afternoon of the year.
Local context
Heat arrives early
NOAA normals for Las Vegas show the average high climbing from 78.5°F in April to 88.5°F in May and 99.4°F in June.
Drains and airflow
ENERGY STAR says a plugged condensate drain can cause water damage and affect indoor humidity, and that airflow problems can cut efficiency by up to 15 percent. More for nearby homeowners: AC maintenance and AC leaking water.
FAQ
When should I have my AC checked before summer? ENERGY STAR recommends a cooling check-up in spring, before the hot season. Why does a clogged condensate drain matter? ENERGY STAR says a plugged drain can cause water damage and affect indoor humidity.
