During the hottest parts of the summer, an inefficient HVAC system can run for much of the day. Since older units tend to be less efficient than newer ones, there are ways you can improve the performance of your air conditioning system. A few common factors that will cause higher power bills is something we at Hal Mechanical would like to do today.
Vegetation Overgrowth Affects Air Conditioner Efficiency
When it comes to mowing the lawn, most homeowners are pretty diligent, though few manage the rest of the landscaping efficiently. Since it is usually tucked out of sight, the unit is easily overlooked. You should make it a point to maintain the area around it with a pair of trimming shears and a trimmer or weed whacker. Space is required for the outdoor condensing unit. Due to weeds, shrubs, and yard debris surrounding, the appliance’s obstructed airflow, which forces the condenser coil to work harder. All that extra effort will be reflected on your energy bill. Also, rodents and other pests are attracted to the vegetation. They will easily creep into your home or gnawing on wires and causing damage to your system when these pests get close the unit. To prevent these problems, make certain to maintain at least three feet of clearance between your condensing unit and any surrounding vegetation.
Neglecting Air Filter Maintenance
When they try to remember the last their filters were changed, most people draw a blank. As they air flow is restricted from these dirt filters, your cooling system demands more energy. In addition to inflating energy costs, a dirty filter can also result in a frozen evaporator coil. You should replace your filter at least every 90 days at minimum. It is recommended you check on the filters every 4-6 weeks, however for those living in the Vegas desert.
Skipping Routine AC Tune Up
It is always recommended you have your central air conditioning tuned up before you turn it on each year. If anything needs to be repaired or replaced is done by a certified technician, checking over the major components of your unit to see. Maintain the various parts of your AC running at peak efficiency is key to keep your cooling bills in check. During routine maintenance, your tech will also check your coolant levels. If your coolant level is low, your unit has a leak and that needs to be fixed ASAP.
Is it Cheaper to Maintain a Constant Temperature AC?
It is a waste to keep an empty home cool. You can manually turn the thermostat to 78 or 80 degrees prior to you leaving in the morning, once home, drop it to 75 degrees. As long as your unit is running efficiently, your home should cool relatively quickly. This task is automatically performed when you efficiently use a programmable thermostat.
Not Upgrading Old AC Unit
The U.S. Department of Energy estimates that upgrading to a new HVAC system will cut cooling costs by as much as 50%. HVAC systems produced 20 years ago require much more power than today’s high-efficiency systems. Along with higher energy bills by holding onto a unit well past its prime, you are likely to have higher repair bills. Consulting with a professional is best to help you decide when it’s time to opt for a new.
