In Salt Lake City, summer heat isn’t just uncomfortable—it can wreak havoc on your home. During July heatwaves, air conditioners run longer and harder, helping us stay cool. But few homeowners realize that an overworked AC unit can quietly cause serious water damage.
In places like West Jordan, Sandy, and South Salt Lake—where older homes or crawl space HVAC setups are common—small leaks from your cooling system can lead to major issues like mold, warped flooring, or even foundation damage.
This post breaks down why air conditioning systems cause water damage during the hottest months, where to look for leaks, and how to protect your home during Utah’s summer peak.
Why AC Units Leak During Utah Heatwaves
When your AC system cools your home, it also removes moisture from the air. That moisture drains away through a condensate line. But if that line gets blocked—or if the system malfunctions—water has nowhere to go, and it ends up inside your home.
Here are the most common issues we see in Salt Lake City homes:
- Clogged condensate lines from dust, algae, or debris
- Cracked or rusted drain pans under air handlers
- Improper insulation or installation, especially in attics or crawl spaces
- Frozen evaporator coils, which thaw rapidly and overflow
- Disconnected lines in older systems with DIY repair history
These problems are especially common during long heatwaves, where the system never gets a break. And when your HVAC is installed in tight spaces—like under the house or in the attic—leaks may go unnoticed until damage sets in.
Trouble Spots in Salt Lake Homes
We’ve seen AC-related water damage across all types of homes in the Salt Lake Valley. These are the highest-risk locations:
Crawl Spaces
In older neighborhoods like Sugar House and Millcreek, HVAC units are often tucked under the house. Leaks here can saturate insulation, attract pests, and warp subflooring.
Basement Utility Rooms
Many Salt Lake homes use the basement for HVAC access. If condensation overflows here, it can damage drywall, baseboards, and even seep into living areas.
Attics and Upper-Level Closets
Some newer homes in Draper and Herriman have AC units or ducting installed overhead. A failed drip pan here can damage ceilings and light fixtures below.
Warning Signs of AC Water Damage
Not sure if your home is at risk? Here are common signs we look for during July inspections:
- Musty odors from vents or HVAC closets
- Puddles around the indoor unit
- High indoor humidity despite AC usage
- Water stains on basement walls or ceilings below attics
- Mold or mildew smells in crawl spaces
If you spot any of these issues, take action before damage spreads.
How to Prevent HVAC Leaks This Summer
Prevention is key, especially as Salt Lake hits its hottest weeks. Here are homeowner essentials:
- Schedule an HVAC tune-up before or during peak heat
- Clear the drain line of algae or clogs—DIY or pro
- Replace corroded or cracked drip pans
- Use a secondary pan or moisture sensor to shut off the system before flooding
- Change your air filters monthly to reduce system strain
- Install a dehumidifier if your home’s interior is still humid
These steps are especially important for homes with limited ventilation in tight spaces.
