furnace repairWhen it comes to HVAC systems, many people don’t understand how they work or the maintenance involved. But considering the fact that two-thirds of all homes in the United States have air conditioners, it’s important for all homeowners to have a basic understanding of the HVAC system in their home. Here are some answers to common questions about HVAC systems.

  1. How often should the filters be replaced on HVAC systems to avoid the need for an AC or furnace repair?
    Air conditioners use about 5% of all the electricity produced in the United States, at an annual cost of more than $11 billion to homeowners. However, all HVAC systems can run more efficiently when the filters are changed promptly. According to Onehourheatandair.com, “There’s no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate…When light is obscured by captured dust and dirt particles, the old filter should be changed.” Remember: If your AC isn’t blowing cold air but the appliance seems to be running, change the filter!
  2. If my A/C and furnace are in good working order, should I still replace them?
    The typical rule of thumb is that homeowners may need to replace their home’s heating system if it’s more than 12 to 15 years old, requires frequent repairs, doesn’t supply sufficient warmth or cold, cycles on and off irregularly, consumes increasing amounts of energy, and emits unusual noises. Still, higher energy systems are becoming the norm due to their energy savings — furnaces with AFUE ratings between 90% and 95% are considered “high efficiency” furnaces, and even though they may cost more up front, they can save money and energy over time and usually have advanced features. If your unit is 10 years old, it’s time to start saving for a replacement.
  3. How much money can be saved with energy efficient heating and HVAC systems?
    The amount of money you can save with HVAC systems that are energy efficient varies depending on the unit and the way you use it. That being said, with a super efficient air conditioning system and furnace that are installed correctly, you can cut up to one-third off your monthly energy bills.
