It’s no secret that HVAC unit replacement is a major expense. Even when you work with the best, most reputable HVAC companies, having a furnace, air conditioner, or other HVAC equipment replaced does come at a substantial cost. For this reason, it’s to your advantage to ensure your current HVAC system lasts as long as possible. Here are a few tips to help you do just that.
Most homeowners should change their HVAC filters every two or three months. If you have pets, or if someone in your home has allergies, you may want to change your filter monthly. When the filter is clear, your HVAC system does not have to work as hard to push air through the system. This reduces wear and tear on the unit over time. Frequent filter changes also keep your furnace and air conditioner cleaner, and cleaner units tend to last longer. If you have trouble remembering to change your filter, set a reminder in your phone.
Have your HVAC contractor come out once a year to perform routine maintenance on your system. They’ll lubricate moving parts, tighten any loose connections, and make sure your system is adjusted for optimal performance. The money you spend on annual maintenance will save you more money down the road by extending the life of your equipment.
Is your system making a rattling noise? Maybe there’s not as much air coming from one of your vents. Don’t ignore these little problems until they become big ones. Instead, contact an affordable HVAC repair service immediately. If you fix problems when they are small, you prevent additional wear and tear on the equipment and extend its lifespan.
Sometimes, people close vents in certain rooms that they don’t want to heat or cool. But this actually makes your HVAC equipment work harder since it increases the pressure in your ducts. If you keep all of the vents open, your furnace or air conditioner won’t have to work as hard, which will cause it to last longer.
This tip mostly applies to outdoor air conditioner units. Sometimes, people try to hide their air conditioners behind landscaping or a fence. But this restricts airflow to the unit, which forces it to work overtime. For optimal AC function and the longest life, your air conditioner needs “room to breathe.” A good guideline is to make sure there is 3 feet of empty space around your AC unit.
If you follow the tips above, you should get more years out of your furnace, air conditioner, and other HVAC equipment.
