As certified HVAC technicians, our DDI Southeast team loves answering questions about the air conditioning units we service. It’s our goal to not only repair your AC unit but also educate homeowners on how to best care for their systems.
Here are three of the most common HVAC questions we’re asked during home visits.
1. What regular maintenance does an HVAC system require, and how often should it be serviced?
Maintaining your air conditioner is more than just changing air filters. Regular preventive maintenance performed by a certified AC technician should include, but isn’t limited to:
- Checking refrigerant pressure
- Cleaning the blower and coils
- Inspecting electrical components
- Calibrating the thermostat
It’s best to perform these maintenance checks twice a year – in the spring before the cooling season, and in the fall before the heating season.
2. How can I increase efficiency and the lifespan of my HVAC system?
Performing consistent preventive maintenance is the best way to extend the life of your AC and keep it running smoothly. Regular system checkups allow you to spot and fix small issues before they become expensive emergencies.
In addition to preventive maintenance, these small changes can go a long way to keeping your HVAC running efficiently.
- Keep vents clear of furniture, boxes and toys, allowing air to flow freely.
- Change air filters regularly to prevent debris buildup in your ducts and system.
- Close curtains, blinds or drapes to prevent heat transfer from sunlight, reducing how often your AC unit cycles on.
- Set your thermostat a few degrees warmer in the summer or cooler in the winter to reduce strain on the system.
3. Does adjusting the thermostat up or down really save money on energy bill?
Thermostat adjustments directly affect how often your AC unit cycles on and off, which can have a big impact on your energy bill. In fact, Engery.gov estimates a 10% annual saving on energy costs by adjusting your thermostat 7°-10° for 8 hours a day.
A programmable thermostat can help you easily adjust the temperature in your home on a consistent basis. Try lowering your setting while away from home, such as during work or school hours, or at night while you sleep. Adjusting your thermostat while away on vacation can also help save on energy costs.
