- Learn how regular maintenance can help you stay cool all summer
Easy Ways to Keep Any Home Cool
Every homeowner faces the summer heat, regardless of their cooling system. These tried-and-true strategies set the stage for a cooler, more efficient home.
Rely On Shade and Insulation
- Close blinds and curtains early in the day to keep direct sunlight out.
- Install reflective window film or use sun-blocking drapes on large windows, particularly ones that face south or west. These add an extra layer of protection against radiant heat.
- Add weather-stripping or caulk around windows and exterior doors to seal out hot air. Even small gaps can let your cooled air slip outside.
- Check your attic temperatures. If your attic feels like an oven, your home’s insulation or ventilation may not be up to the task. Check the thickness of the insulation and make sure attic vents are not blocked.
Block Heat at Entry Points
- Use weatherstripping or draft blockers along exterior doors.
- Only open exterior doors when necessary. Frequent opening welcomes a blast of hot, dry air, making it harder for your home’s cooling system to keep up.
Plan Activities for Cooler Hours
- Cook outside or plan cold meals during the hottest parts of the day to avoid heating your kitchen.
- Run heat-generating appliances like the dishwasher or laundry machines after sunset.
Use Ceiling and Portable Fans Wisely
- Set fans to rotate counterclockwise so they create a wind chill effect by pushing cooler air down.
- Place box fans in shaded windows during the evening to pull in cooler outdoor air.
Schedule Preventative Maintenance
- A regular tune-up can help any cooling system run more efficiently and prevent big issues. If you’re not sure when your last maintenance appointment was, call in a pro before the next heat wave hits.
Smart Tips for Homes with Central Air Conditioning
Central air systems are common for a reason, but they only perform at their best with some routine care.
Change Air Filters Regularly
Dust and pollen from dry, windy days can clog filters quickly. Swap filters every month during heavy-use periods to improve airflow and avoid straining your AC.
Check Vents
Make sure no furniture or curtains block airflow. Vacuum dusty vents every few weeks so your system isn’t working uphill.
Clean Ducts
Dust and allergens can build up in your air ducts, blocking airflow and lowering efficiency. Schedule a professional duct cleaning to keep your system running smoothly and improve your home’s air quality. Regular maintenance prevents wear and tear, keeping your central air system in top shape.
Set and Use Your Thermostat Wisely
Keep thermostat settings stable rather than constantly cycling the temperature up and down. Use programmable thermostats to adjust the temperature when you’re away or asleep. A few degrees higher during those times can reduce your electric bill significantly.
Don’t Ignore Small Problems
If you hear unusual noises from your unit or notice less cool air, don’t wait until the system fails. Early help can solve the problem quickly and may help you avoid expensive problems. Other warning signs to watch out for include odd smells, higher energy bills, and weak airflow.
Annual Professional Maintenance
Book a professional A/C inspection and tune-up before the hottest weather arrives. Certified technicians will:
- Clean condenser coils
- Check refrigerant levels
- Hunt for leaks or minor parts failures before they become major
Keeping Cool with a Swamp Cooler
Swamp coolers (evaporative coolers) are a popular, energy-saving option for homes in dry (low-humidity) climates. They can be highly effective—but only if maintained properly.
Replace Water Pads Regularly
Water pads (also called cooling pads) are thick, porous materials inside a swamp cooler that stay wet with water. Most common swamp coolers use multiple pads to maximize cooling, but some smaller units may have just one. As warm air passes through these damp pads, the water evaporates, cooling the air before it’s blown into your home. These pads are key to the evaporative cooling process, helping to lower indoor temperatures naturally and efficiently.
Although water pads do the heavy lifting in cooling your air, they can get clogged or harbor bacteria. Replace them at the start of each cooling season, and check them monthly. Dirty or old pads reduce cooling power and air quality.
Drain and Clean the Drip Pan
Standing water breeds bacteria and mold faster than you might think. If your cooler sits unused for a while, drain and wipe the pan before the next use.
Keep It Clean and Clear
- Remove mineral buildup on the pump and internal parts every month.
- Wipe away dirt and debris from the exterior louvers.
- Make sure the fan motor is running smoothly, with no burned-out smells or strange rattles.
Maintain Good Airflow
Crack open a few windows in the rooms you want to cool. Swamp coolers work best when there’s some cross-ventilation.
Get Annual Service
Schedule a yearly inspection with a cooling pro to check the pump, float valve, pads, and motor before demanding summer weather.
Maximizing Comfort with Ductless Mini-Split Systems
Mini-splits are an ideal solution for zoned cooling and hard-to-reach spaces, but they require their own care routine.
Keep Filters Clean
Remove and clean filters every few weeks or more often if you have allergies or dusty conditions. A clogged filter chokes airflow and can force the system to work overtime.
Monitor the Outdoor Unit
Give the outdoor condenser plenty of breathing room. Trim back bushes, remove debris, and make sure leaves aren’t blocking the airflow.
Clean the Coils and Check the Drain Line
Dust and buildup on the indoor unit’s coils can hurt efficiency. A quick wipe with a soft dry or slightly damp cloth can go a long way. Periodically check that the drain line is clear and not backing up water into your home.
Don’t Overload the System
Mini-splits are excellent for dedicated rooms but aren’t designed to cool the entire house, unless multiple units are installed. Ask a trusted HVAC technician to assess your home’s layout and cooling needs to recommend the right number and placement of units for effective whole-home comfort. Keep doors and windows closed in cooled areas to maintain maximum efficiency.
Annual Professional Maintenance
Like any system, a ductless mini-split needs an annual tune-up to stay at peak performance. HVAC technicians can handle lubrication, refrigerant checks, and electrical inspections to keep your system running smoothly through peak heat.
Keep Cool and Comfortable All Summer Long
A few proactive steps now can mean the difference between a relaxing summer and one full of headaches and hot nights. By taking care of your home’s cooling system and using simple money-saving strategies, you can stay comfortable without wasting energy or risking a system breakdown.
