A home heating and air conditioning system uses up at least 47% of the energy in an average household, making it the largest electricity consumer. If your AC isn’t operating efficiently, it could be driving up your energy bills. You’ll end up frustrated, trying to keep your home comfortable while paying an ever-higher electric bill.
If you suspect the HVAC is the culprit, conduct an energy audit first. When you have the report, show it to an HVAC contractor for recommendations on making your system more efficient. Here are the reasons the unit is using more power than it should.
It’s Faulty
Issues such as worn-out parts, broken seals, and clogged filters make your system work harder. The result is that it uses more energy, causing your utility bills to go up. In some cases, replacing the system is the only way to fix the problem.
However, consult HVAC repairs and installation experts first. Sometimes, minor repairs resolve the issue, and the system works efficiently again. When the issues keep arising, it’s time for a replacement.
The System Is Old
If your system is over ten years old, it may be time to replace it with a newer, more energy-efficient model. Older systems have worn-out parts, which make them less energy-efficient. They also have a lower SEER (Seasonal Energy Efficiency Ratio). Replacing your old system with a new one can be expensive, but it will save you money in the long run. Go for a system with a SEER of at least 13.
It’s the Wrong Size
Sometimes, homeowners choose an HVAC system that’s too small for their home. Other times, they choose one that’s too big. Getting the wrong size is a mistake that leads to energy inefficiency. A system that’s too small will have to work overtime to maintain the desired indoor temperature.
Conversely, a large system will cool or heat the space too quickly, short cycling. Both scenarios increase energy consumption, leading to higher utility bills. Consult a professional to help you choose the right size for your home.
It’s Not Properly Maintained
Your HVAC system needs regular maintenance to function efficiently. Most homeowners don’t realize this and only call for repairs when something breaks down. However, it’s usually too late, and the system has significant damage.
Yearly maintenance catches issues early enough before they turn into expensive repairs. Furthermore, it increases the system’s efficiency, lowering your energy consumption and utility bills.
It Has Incorrectly Set Thermostats
The system will have to work harder if your thermostats are set too high in summer and too low in winter. That’s because it has to remove or add more heat to reach the desired temperature. Invest in a programmable thermostat and set it at 78F in summer and 68F in winter.
Doing so will reduce your energy consumption by up to 30%. If possible, invest in a smart thermostat. These devices come with features such as geofencing and occupancy sensors, which make them even more energy-efficient.
Leaky Ducts
If there are leaks in the ductwork, conditioned air will escape before it gets to the rooms. The system will have to work harder to compensate for the lost air, thereby using more energy. Inspect the ducts and seal the leaks with mastic or metal tape. Also, clean the ducts to get rid of dirt and debris. Clogged ducts make the system work harder as well.
Inadequate Insulation
If your home isn’t adequately insulated, conditioned air will escape, making the system work harder. The harder the system works, the more energy it uses, leading to high utility bills. Check the insulation in your attic and walls and add more if necessary. Also, seal air leaks around doors and windows. Doing so will improve the system’s efficiency by up to 30%.
Avoid Constant Frustrations
HVAC systems are a significant investment. Check that they work efficiently to avoid high energy bills. You’ll avoid constant frustrations as you try to keep up with the escalating costs. You’ll also get to enjoy optimal indoor comfort all year round. If your system is inefficient, talk to professionals about replacement options. They’ll help you choose a system that best meets your needs and budget.
