Maximizing your HVAC unit’s efficiency while saving money
If there were a magic thermostat, keeping your house comfortable and your energy bill low would be easy. This thermostat would know to anticipate your every move, knowing when you come and go, tracking outdoor humidity levels and watching the calendar to adjust by one degree with every half rotation of the Earth. Without that, most of us just rely on common sense. When it’s hot outside, indoor should be cool. When it’s cold, making your home warmer is essential.
While the magical thermostat doesn’t exist, the key is the same: Your home should be the most comfortable for you. There is absolutely no point in having an HVAC unit if you’re going to sweat all summer or freeze all winter. For most people, this means a daytime temperature of 70 to 75 degrees, and a nighttime temperature of 65 to 72 degrees. The keys to saving money on your energy bill are directly related to these temperature ranges, but in ways you may not know. Setting your thermostat to the top of the day range will be cheaper, especially during peak AC usage hours (3PM to 7PM), but again, it’s all about comfort. Don’t sacrifice your comfort in an effort to try to save a few bucks; just a 1 degree temperature increase can save you money.
At night, feel free to lower that temperature. Your HVAC systems actually does less work at night (meaning a lower bill for you!) You can turn it down without spending more since your unit doesn’t have to fight against the sun or warmer outdoor temperatures to maintain the lower indoor temperature.
In the winter months, the ideal range is between 60 and 65 degrees. During winter months, it’s easy to throw on another layer. The main concern with your home’s or business’s indoor winter temperature is keeping your home above freezing to prevent your pipes from freezing, so if it’s possible to keeping your home between 50 and 55 degrees for 7 or 8 hours a day, you can save you 30% on your bill.
While you may have heard some of that before, one of the biggest questions we get about heating and cooling your home is about leaving your HVAC system on while you’re away from home.
You probably turn off your air conditioning while you’re on vacation in summer or turn off thefurnace when you head to the slopes in winter; as you should anytime you leave home for more than 24 hours. However, turning your systems on and off while you’re gone for shorter amounts of time, particularly during very hot or very cold weather, can actually end up costing you more money!
It may sound counterintuitive to leave your unit running during the day, but think about your home’s construction. Each home is insulated to help maintain the internal temperature, and prevent extreme outdoor temps from sneaking in. If you turn it off while you leave on a hot day, and then turn it back on, it can take your unit hours to get through the insulation. Your unit will be working to cool a higher temperature for a longer amount of time, costing you more!
If you’re looking to save money and energy, let’s revisit those temperature ranges from above.
- In the summer, boost your AC between 5 and 8 degrees above your ideal temperature.
- In the winter, lower your heater between 5 and 8 degrees below your idea temperature.
- Only turn the unit off if you’ll be gone for more than 24 hours.
