When the cold winter air gives way to the climbing temperatures of spring and summer, you’ll want to be able to stay cool without having to empty your wallet for energy bills. We have put together a list of six HVAC tips you can take to save money on your utility bill without sacrificing comfort.

1. Replace old air conditioning units with newer, efficient models.

If you have an older unit that has not been properly maintained, invest in a new model. The replacement costs may seem daunting , but in the long run , they are well worth it. Manufacturers such as Mitsubishi, Trane, Rheem and others are labeled with Energy Star ratings. Energy star products us up to 50 percent less energy than other manufacturers.

2. Invest in a programmable thermostat. 

It’s easier to save energy with a programmable thermostat than a regular one because you don’t have to think about it each time you want to change the temperature. You pre-program your settings so that the thermostat raises the temperature while you’re at work and asleep, and kicks on the air conditioning when you’re at home and awake. With “smart”  programmable thermostats, you can even control the temperature from your smartphone.

3. Don’t forget about your air filters.

Air filters should be replaced monthly to promote a more efficient system performance. Clogged or dirty air filters can cause a disrupt in the airflow and even lead to health concerns.

4. Protect your HVAC unit from sun and debris. 

An awning or tree can provide shade to your unit and cut energy consumption while helping your unit operate more smoothly. However, note that shrubbery or branches that can get into the system and can hinder the systems performance and may lead to permanent damage.

5. Make sure that your vents are clean and open.

It may be obvious but it is truly remarkable what you may not notice about your own home. Vents can be accidentally shut for cleaning purposes and never reopened. If you notice an unusually warm room or area in your home, don’t forget to check the vent.

A clean vent also keeps debris from flowing through your home. Dirt and dust can easily collect and can be overlooked; be sure to focus on the inside of your home as well as the outside and ensure your vent and air filters are in good condition.

6. Think gravity.

Heat rises. During those hot summer months, the heat in your home will rise to the ceiling or the second floor of your home. To help that hot air on its way out of your home, fans can be a great tool.

Either ceiling fans or standing fans help move the air around the room, creating a cooler environment for your family. Good air circulation helps your home maintain an even temperature, giving your HVAC a chance to work less.
