If you find yourself hesitating to adjust your thermostat because it might increase your utility costs, there may be a few things in your home that are affecting your HVAC system’s efficiency. In today’s post, the local HVAC contractors at GO Green Air discuss the common causes of HVAC system inefficiency.
1. Thermostat malfunction. No matter what type of HVAC system your home has, the first troubleshooting step is always to make sure that the thermostat is working properly. Resetting the thermostat or replacing its battery is often enough to fix HVAC problems. If you have a traditional mercury or bimetal thermostat, consider getting a programmable thermostat. It can help improve HVAC efficiency by automatically adjusting HVAC output to meet your heating and cooling needs.
2. Clogged air filters. HVAC systems are equipped with air filters that catch dust and other pollutants. They eventually require replacement when they’re full, otherwise they end up blocking airflow in your HVAC system and affecting its efficiency. Most types of whole-home HVAC systems require new air filters every three months, or once a month during seasons of heavy usage. Check the air filters at least once a month if you’re unsure how often you need to replace your air filters. If you have a smart HVAC system, it may have a feature that will remind you if the air filters are due for replacement.
3. Leaky insulation. Every home has an insulated enclosure made of the exterior walls, the attic, and fenestrations (windows, entry doors, and skylights). Ideally, all these parts should have sufficient insulation to reduce thermal transfer and maintain indoor temperatures, ultimately resulting in reduced output from your HVAC system. If you notice drafts or cold spots around the house, or if the ceiling feels way too hot during the summer season, you’ll need to address leaks in the insulation in these areas.
4. Leaks in the air ducts. A leaky air duct system would only deliver a fraction of your HVAC output into every room, which can dramatically affect HVAC efficiency. Since air ducts are hidden from sight, you have to have your air duct system tested by an HVAC professional, then repaired as needed. You can take preventative steps by having your air ducts cleaned and sealed every five years.
