Las Vegas summers are not like summers anywhere else in the country. Sustained temperatures above 110°F for weeks at a time, UV radiation intense enough to fade fabrics and crack rubber seals, and an HVAC system that runs virtually nonstop from June through September — preparing your home for this season is part maintenance, part cleaning, and entirely necessary. This checklist covers everything you should do before the heat arrives.
In Las Vegas, your air conditioning system is not a comfort amenity — it’s a life-safety system. Before summer, replace all HVAC filters (and check them monthly once temperatures rise). Have the system professionally serviced if it hasn’t been in the past year: coils cleaned, refrigerant levels checked, and drainage lines cleared. A clogged condensate drain can cause your AC unit to shut down or flood during the summer months when it’s working hardest. Clean the outdoor condenser unit by hosing down the fins (with the power off) to remove the dust and debris that reduce efficiency.
Ceiling fans accumulate dust on their blades over the winter and spring months — and you’ll want those fans running effectively all summer. Wipe each blade with a damp microfiber cloth, then dry. Make sure fans are set to run counterclockwise in summer (the airflow direction that creates a wind-chill effect). Clean light fixtures throughout the home — dust on light bulbs reduces their efficiency and creates a slight burning smell when the lights are on, which is amplified in summer heat.
Solar shades, blackout curtains, and reflective window films do significant work in a Las Vegas summer by blocking radiant heat. Before the season starts, wipe down solar shades with a damp cloth to remove dust that has accumulated over winter. Wash light-blocking curtains according to their care labels. Inspect window films for peeling edges — the extreme UV exposure and thermal cycling of Las Vegas windows causes film adhesive to fail over time, and a peeling film doesn’t block heat effectively.
Your refrigerator works harder in summer, especially if it’s in a garage or near a window that receives direct sun. Pull it away from the wall and vacuum the condenser coils — dust-covered coils force the compressor to work harder and can cause premature failure. In Las Vegas, where garage temperatures can reach 140°F, a refrigerator or freezer in a non-air-conditioned garage may struggle to maintain proper temperatures. Consider relocating garage refrigerators to an interior utility room if possible during peak summer months.
Clean and cover or store any outdoor furniture cushions before the intense summer sun fades and degrades them. Power wash the patio or pool deck to remove winter grime before it bakes on in the summer heat. Inspect and clean the pool filter and skimmer baskets. Clear any desert vegetation debris from around the house foundation — dry vegetation is a fire hazard in the hot, dry summer months, and it attracts scorpions, which are more active in summer. Check and clear window well drains and garage floor drains of debris.
Because Las Vegas homes are sealed against the heat for most of the summer, indoor air quality is a meaningful concern. Change HVAC filters monthly. Consider running an air purifier with a HEPA filter in bedrooms, especially if family members have allergies or asthma. Have carpets and upholstered furniture cleaned before sealing up the house for summer — any biological material (pet dander, dust mite waste, tracked-in pollen) that remains gets recirculated through your HVAC system all summer long. A professional clean before the heat arrives pays dividends in air quality for the next four months.
