HVAC Energy Saving Tips for Summer

Warmer weather is here, and it’s not leaving for several months. As the outdoor temperature gets higher, so might your energy bill. Cooling your home can be quite an expense, but if done properly, it does not have to break the bank. Below are ten summer energy saving tips that can help keep money in your wallet while keeping your home cool and comfortable.

Change Your Filters
Dirty, clogged or blocked air filters limit air flow throughout vents and ductwork which will cause your air conditioning system to run longer and work harder than necessary to cool your space; thus, increasing energy usage and wasting money. We recommend cleaning or replacing your filters regularly to maximize performance.

Install a Smart Thermostat
A smart thermostat heats or cools your home to the perfect desired temperature only when you need it. You can program and control a smart thermostat from anywhere through your wireless device so it learns your schedule and adjusts the temperature accordingly. Some smart thermostats even have sensors that can tell if someone enters a room, in which case they will adjust the temperature to be more comfortable. This is very different from manual thermostats which cool a home even when no one is there – wasting a bunch of energy. According to Energy Star, heating and cooling costs make up nearly half of your annual energy bill. A smart thermostat can therefore make a sizeable positive impact on your wallet.

Check Your Insulation
Most people tend to think of insulation as keeping heat in the home during the winter, but it is just as important at keeping heat out during the summer. Make sure your current insulation is sufficient to sustain a comfortable temperature without allowing a lot of the cool air to escape through walls and ceilings. The attic is an important place to check for this as the sun will most likely be cooking your roof throughout the middle of the day. The better shape your insulation is in, the more energy you will save by your air conditioner not having to work as hard to distribute new, cool air.

Use a Dehumidifier
In certain areas, high humidity is a big part of summer, and high moisture levels can cause discomfort and even health risks if not appropriately handled. A lower humidity level in your residence can provide increased comfort, lower the risk of serious health issues and even lower your utility bills. Your air conditioning system is designed to remove moisture from the air and decrease humidity levels; however, adding a dehumidifier to your forced-air system can do the job more efficiently and allow your unit to solely focus on cooling the house and save energy in the long run.

Prevent Leaks
Seal any cracks and openings around windows, walls and doorways to prevent warm air from leaking into your home from outside. Use caulk or other weatherstripping materials to fix any air leaks that may be present. Areas where a high possibility of leaks may exist are doorways, leaky windows, along floorboards and areas with attic access.

Use Fans Wisely
Ceiling fans are a great way to circulate the cool air that is being distributed by your air conditioning system; however, keep in mind that fans cool you down because of the wind they provide. Fans do not actually lower the temperature of the space, so be sure to turn them off when leaving a room to save electricity.

Close Off Unused Areas
Make sure to close off any spaces that you will not be spending much time in such as unused bedrooms or storage closets. This is an extremely easy way to efficiently utilize the cool air being distributed by your air conditioning system and not waste it on unused space. Doing so allows your space to reach a desirable temperature faster and makes it easier on your unit while saving energy and money.

Arrange Electronics Appropriately
Avoid placing appliances or electronics near your thermostat as it will sense the heat that is given off by these machines. This will cause your air conditioning system to think the temperature of the room is higher than it is and work harder than necessary to cool the space. This especially applies to lighting, so try not to place lamps close to the thermostat due to the large amount of heat that they give off when turned on. In general, do your best to keep appliances or electronics off, when possible, to avoid adding unnecessary heat to your home.

Use Your Windows and Blinds
If the outside temperature in your area reaches a comfortable level at night, consider turning off your air conditioning system and opening some windows before you go to bed. Then, in the morning, close the windows to capture the cool air, and keep it inside. Additionally, if possible, close your blinds during the day to keep the sunlight out. This will help to keep the overall temperature down.

Schedule Maintenance Now
It is always a good idea to have your cooling equipment checked out by a professional, especially before mid-summer when it will be working its hardest. If there are any problems, it is best to discover them now before you must temporarily live without it while it gets fixed. It also will be easier to schedule an appointment with a service technician before it becomes the busiest time of the season. With these tips, you can look forward to lower energy bills, a comfortable living space and the good feeling of saving energy.
