7 Tips for Operating Your Mini-Split Heat Pump in the Summer
July 03, 2018
If you own a mini-split heat pump system, you probably already know about the benefits of efficient heating and cooling, zone temperature control, and quiet operation. Mini-splits require little maintenance and are easy to operate. To get the most out of your mini-split heat pump system, check out these seven tips to maximize it’s efficiency, lower energy costs, and enhance your comfort during the summer months.
Choose your comfort level.
Don’t get hung up on the number. When choosing the temperature setting on the remote for your mini-splits, you may discover you need to set it higher or lower than you would expect. Part of this is due to the fact that the temperature is measured at the level of the indoor air handler unit, which is typically 7-8 feet off the ground. Find a setting your most comfortable with and stick with that.
Let your system run continuously.
Set it and forget it. A mini-split system uses less energy and keeps temperatures most consistent when it runs continuously, as in, 24/7. You also don’t need to turn the units on and off or adjust temperature settings when you’re away like you might with a central heating and cooling system controlled with a thermostat.
Set the fan to AUTO.
No need to pick a fan speed. The air handlers will automatically adjust the fan speed to maintain comfort and minimize energy usage when set in the AUTO mode.
Keep the air flowing with routine maintenance.
Perform some routine maintenance to make sure your system circulates cool air efficiently and effectively. Remove the cover of the air handlers to wipe down evaporator coils with a soft cloth and clean the air filter periodically during the summer. Also, ensure there isn’t debris in the outdoor unit. You can clean it off with a garden hose, just make sure you shut the power off to the system before you do so.
Check for drainage.
As your system cools your home, condensation builds up on the evaporator coils and should drain outside. Check the outdoor condenser unit for condensate draining away. If you don’t see any while your system is running, it may not be draining properly, and you should contact a trained heating and cooling professional.
Block the sun by closing shades and curtains.
The warmth of the summer sun will heat your home and your mini-split system will need to work a little harder to keep it cool. But you can give your cooling system a break by keeping blinds and curtains closed during the day, in particular in the late afternoon when temperatures are warmest.
Leave interior doors open to circulate cool air.
Let the air flow by leaving interior doors open. The difference between leaving doors open and closed could be as much as 5 °F. Again, this will help your system to run less than it needs to, saving you energy and improving its lifespan.
