HVAC stands for Heating, Ventilation, and Air Conditioning.

SEER, or Seasonal Energy Efficiency Ratio, measures the efficiency of heating and cooling systems. The Department of Energy (DOE) requires all new residential HVAC systems to have a minimum SEER rating of 13. Typically, modern systems range from 13 to 21 SEER. A higher SEER rating means better energy efficiency. Choosing an HVAC system with a high SEER rating can reduce your monthly energy costs. Additionally, the DOE is set to introduce new efficiency standards in 2023.

The lifespan of your HVAC equipment varies based on several factors such as maintenance, installation quality, climate, and usage. Typically, heaters can last between 15 and 20 years, while air conditioners usually have a lifespan of 10 to 15 years. Regular maintenance and proper care can significantly extend the life of your HVAC system.

Air filters play a crucial role in enhancing your indoor air quality by trapping dust, dirt, pollen, and other pollutants before the air circulates through your home. Over time, filters can become clogged, putting strain on your HVAC system and potentially leading to repairs or breakdowns. To prevent these issues, it’s recommended to check your air filter at least once a month. If the filter is dirty, either clean or replace it based on the filter type.

Setting your thermostat correctly can prevent unnecessary strain on your HVAC system, which could otherwise lead to damage and premature failure. During the summer, aim for a thermostat setting of 75-80 degrees Fahrenheit. In the winter, keep it between 68-72 degrees Fahrenheit. Adjusting your thermostat by 10-15 degrees for at least eight hours can lower your heating bill by 5-15%, with a potential 1% savings for each degree adjusted. According to EnergyHub, each degree you lower your heat can save up to 3% on heating costs.

Regular maintenance by qualified professionals is essential to keep your AC and heater running efficiently for years. Experts recommend scheduling maintenance annually for each system—AC in the spring and heater in the fall. This ensures your systems are ready to provide comfort throughout the year without unexpected issues. Additionally, many manufacturers stipulate annual maintenance to maintain warranty coverage.

Ductless mini-splits are an excellent solution for heating and cooling areas that a traditional ducted system can’t reach, such as finished basements, sheds, garages, living rooms, and new additions. These systems don’t require ducts and are called “mini” because they are smaller than conventional HVAC units. They are “split” between an indoor unit and an outdoor unit. Each indoor unit is designed to heat or cool a specific room or area. Ductless mini-splits are known for being more efficient and quieter than traditional systems. With proper installation and maintenance, these systems can last 10-15 years.

A heat pump is a versatile, all-in-one heating and cooling system that is installed outside your home. It works by transferring thermal energy between spaces to either heat or cool your living area. In heating mode, the heat pump extracts heat from the outside air and moves it indoors. In cooling mode, it removes heat from the indoor air and releases it outside. Heat pumps are generally more environmentally friendly than traditional HVAC systems that rely on fossil fuels.

Your AC or heater will often provide warning signs when they are nearing the end of their lifespan. The key is to recognize these signs early.
