How Long Do HVAC Systems Last?

An HVAC system is an important investment that needs regular care. If you provide your system with regular inspections and maintenance, an HVAC unit can last 25 years. If your system isn’t inspected or maintained a few times a year, an HVAC unit may only last 5 to 10 years. Follow these suggestions to maximize the full capacity of your unit.

Track Utility Bills

Closely monitor your utility bills each month. If there is a sudden increase in costs with any known adjustments to your property’s temperature, there is likely an issue with your HVAC system. Energy bills are the first inflated cost when a unit is experiencing difficulties. Save money by scheduling inspections before maintenance increases your bills.

Change Air Filters

Air filters play a significant role in determining the health of your HVAC system. Replacing air filters once a month goes a long way to increase system lifespan. Don’t wait any longer than three months to replace air filters.

Check for Leaks

Leakage is a big sign that your HVAC system is experiencing damage, and water and air leaks are the two types to act quickly against. Water leaks are caused by clogged drain lanes experiencing condensation. Other factors that clog drain lines include debris like dust, dirt, and algae. Luckily, no gas is involved with water leaks, so health concerns aren’t a pressing issue. Water leaks are the most common in the summer when temperatures rise, so be sure to change filters monthly during this season.

Air leaks can be found by listening to your system, and they occur around panel gaps or areas with missing screws. Air leaks typically result from improper installation. Contact a professional for repair.

Monitor System Efficiency

Have you noticed that your heating or cooling is a bit off from its regular performance? Is air quality lacking? Contact a professional for a quick, much-needed adjustment.

Contact HVAC Providers

Your best bet for prolonging the life of your HVAC system is scheduling regular inspections and maintenance with a professional before minor damages become expensive repairs.

HVAC Maintenance Plan Benefits

Service Unlimited’s commercial HVAC maintenance follows through with our commitment to quality. Listed below are the advantages of our preventative maintenance:

HVAC Equipment Life Expectancy

Your commercial HVAC system is a significant investment. Regular maintenance planning promotes your system’s longevity and ensures you get the most out of the investment.

Reducing Costly Repairs

Service Unlimited offers emergency repair services, but it’s more efficient to identify issues before they become problems. We can save you money by maintaining or replacing a piece of equipment before it breaks down.

Safe, Healthy Environment

Indoor air quality and the proper operation of your HVAC system work together to provide a high-quality environment for employees and customers.

System Efficiency

Every machine requires a preventative maintenance schedule to operate at peak performance. Maintaining your equipment will keep it functioning more effectively and efficiently.

Reducing Downtime

Buildings that offer few distractions help your employees to do their jobs more efficiently. An overheated or chilly workplace reduces productivity, while a well-maintained HVAC system helps increase it.

Reducing Reactive Maintenance

When your air conditioner or heat pump breaks down, your maintenance costs will increase due to emergency response time and the drop in system efficiency. Proactive maintenance eliminates last-minute concerns and preserves the performance of your HVAC system.
