Ah, summer, when thoughts turn to air conditioning. We have to have it, especially when we are trying to beat the summer heat!
We asked experts for their top tips on keeping your air conditioning running cold and keeping your house cool this summer.

Do a visual inspection of your condensing unit – this is the piece of equipment that’s outside your home. Your condensing unit contains important heat-exchange equipment required to cool your home efficiently. The condensing unit requires free and clear air flow in order to work at its best. If there is any debris blocking airflow, you are losing efficiency in your system. Be sure your air conditioner is turned off, then head outdoors.
Check that there are no branches or leaves covering your AC unit. If there are other items like plants or bushes that are near your air conditioner, they need to be trimmed back or removed. Many homeowners want to try to hide their AC unit with fencing or bushes, but this will inhibit the performance of the unit.
For best performance, you should have about 3 feet of open space surrounding your condensing unit in all directions.

Many people don’t set their thermostat to a realistic temperature. They have it set far below the recommended 78* setting. Air conditioning systems are sized for your home based on target heat load design temps of 75*. When your thermostat is set significantly below that, it will cause it to run nearly the entire day, costing you money.
To keep your home cooler, use blinds and curtains to cut down on sun infiltration.
Our last tip is to use ceiling fans to stay cool, and you will not need to set your thermostat as low. Do ceiling fans help to cool the house? No, but they do help you feel cooler. Ceiling fans cool by evaporating tiny beads of sweat on our bodies. Think of how refreshing a breeze feels on a hot day. Just remember to turn the fans off when you leave the room. While circulating air can help reduce a stale air smell, they cool your body, not the room.

It’s important to check the air temperature difference between the air supply and air output. Check the temperature of the supply air (air being pulled into the large filter intake vent) compared to the air coming out of the vents. A properly running system should have a difference of at least 14 degrees Fahrenheit between the warm air going in and the cool air coming out.
While you are measuring the temperature of the air coming out of your vents, examine the vents themselves. First, check to ensure they are open. Closing vents can make the air flow unbalanced and lead to additional stress on your HVAC system. Next, check to make sure all of your air vents are pointed toward the interior of the room, not the wall or the window.
Then take a look in the attic. If your coil, or air handler, is in the attic, make sure that there is no water in the secondary drain pan that lays underneath it. This could signify the HVAC system needs AC Repair.

A lot of homeowners will set the thermostat up to 80* when they are at work during the day, thinking this will save them money.We receive calls from customers that think there is something wrong with their HVAC when it’s set all day at 80*and their house doesn’t cool down to 70* within an hour.
It’s actually cheaper to leave it set to a lower temperature, around 76*. That way the system won’t have to overwork trying to catch up to the lower desired temperature when you get home. It will also eliminate the stagnant air smell in the home, which can happen when air isn’t circulating.

Your air conditioner can more effectively cool if your home is properly insulated. Proper insulation means 10″ to 18″ inches of insulation in the attic depending on the type of insulation.
You also want to make sure there’s no outside air infiltrating the house. Make sure windows are shut all the way, and check the weather stripping around all doors. If you can see light coming in around the side or under a door, it’s not fully sealed.
The attic access door is one area that a lot of people forget. You want to make sure no air is coming in around the attic access in your home. I recommend that homeowners have an attic tent installed by a HVAC contractor above the attic access. An attic tent insulates the attic access door, to keep hot air from entering the home from the attic. And if your attic isn’t hot, that indicates that your duct work is leaking cold air into your attic, costing you money and lowering the cooling efficiency of your A/C.

Considering that your home’s air conditioning system hasn’t functioned in months the best thing is to have a professional inspect the system to find out it’s status. After all, it’s a mechanical/electrical machine. Have you ever let a car sit idle for months then tried to run it?
Get a high tech HVAC tune-up to understand how the machine is actually performing. A high tech tune-up will include use of digital gauges that send data to a computer to be analyzed, electronic temperature probes which analyze temperature and humidity, and they’ll measure the cubic feet per minute (CFM) that your fan is circulating. This is an investment of around $85 that will likely pay for itself in energy savings alone. Plus you get peace of mind of knowing the actual condition of your A/C system.

Outdoor units can look clean on the surface but dirt can drastically reduce efficiency and cooling capacity as well as shortening the life of the units and components. Keep shrubs trimmed back and debris away from outdoor units as this can cause the same issue as a dirty outdoor system.
If you have a two-story house with two HVAC systems, set the downstairs a degree or two below the upstairs. If the upstairs is set lower it will try to cool the whole house in a losing battle, as it basically becomes the downstairs attic.
Lastly, do not make large temperature adjustments on a programmable thermostat. Set it and let it do its job.
A properly sized system cannot drop the temp in the house during the middle of a 100 degree day. Having the thermostat set at 80* when you are at work and expecting it to drop to 72* at 4:00 in the afternoon is a recipe for perspiration.

We recommend that consumers look at the installation date of their HVAC system. While your older HVAC system may still be running, it could be costing you more than you realize. Replacing systems installed in 2006 or earlier can lead to as much as 54 percent in energy savings. So while the upfront cost of a new unit seems costly, you could see a fast return on your investment.
The other big tip is to consider a connected, programmable thermostat that lets you schedule temperature settings or make changes from anywhere. This gives you the flexibility to change plans, like spending another day on vacation, while maintaining your HVAC system’s “away” temperature settings. Some connected thermostats have the added bonus of continually monitoring your HVAC system health. The American Standard AccuLink™ Platinum 1050 Control is a wifi programmable thermostat that also lets your local dealer access the diagnostics data of your American Standard system. Your local dealer can monitor your system for any alerts and catch minor issues before they become a larger problem.
