According to Business Insider, 60 seconds of downtime caused by heating, ventilation, and air conditioning (HVAC) failure can cost the HVAC industry unexpected stoppages worth a whopping $22,000.

That’s just 1 minute! How much would refrigeration or air conditioning failure cost you in 1 day?

Unplanned downtown can be costly to any business. Avoid losses to your business through routine HVAC maintenance.

Sure, investing in the right HVAC system for your space is critical to keeping people comfortable, maintaining product quality and controlling energy costs. However, that is only the basic step.

Ensuring that your HVAC system works in peak condition is critical to thwarting unplanned closures and unpleasant surprises.

Plus, if you’re a landlord, it’s your duty to provide habitable housing to your tenants – otherwise, they have a right to withhold rent. That’s one more loss to your business that could easily be avoided!

That’s why in this article, we share the top 5 HVAC maintenance tips.

1.   Use a checklist of HVAC maintenance tips.

Developing an HVAC maintenance checklist can help ensure that your HVAC unit is in tip-top shape.

  • Seasonally, check coils, refrigerant levels, heat exchangers, and check burners
  • Inspect or replace belts, filters, and consumables
  • Check airflow and clean all components
  • Check the start cycle of the equipment to assure the HVAC system starts, operates, and shuts off properly
  • Inspect the condensate drains in the system to prevent water damage and adverse indoor humidity levels
  • Lubricate all moving parts to reduce friction in motors and reduce the amount of electricity used
  • Check thermostats for the correct time, date, and temperature settings for the season and business needs

2.   Clean the coils.

Clean HVAC coils allow for your unit to run effectively, efficiently, and reliably. Specifically, you’ll have lower heating and cooling costs, improved indoor air quality, maximum operation efficiency, and better airflow.

On the other hand, dirty condenser coils can cause your:

  • Cooling efficiency to drop by more than 30%. When that happens, your unit is only going to be running at 60-70% effectiveness.
  • Air conditioning (AC) unit not to cool your home like it once did. Its cooling efficiency is going to decline, while the amount of energy the unit consumes is going to increase significantly.
  • The energy efficiency of the unit is going to drop significantly.

3.   Change the filters.

The Environmental Protection Agency (EPA) calls changing dirty furnace filters the most important maintenance task for optimizing your heating system’s energy efficiency.

Here are four good reasons why you should change your HVAC air filters regularly:

  • A clean air filter keeps your home cleaner

This is because it won’t keep circulating the dust through your home’s HVAC system. As a result, you’ll have less dusting to do.

  • Dirty air filters increase your maintenance costs

Although a clogged air filter doesn’t always lead to system failure, it does lead to costly maintenance.

  • Clogged air filters reduce your system’s lifespan

Not only do clogged air filters lead to increased energy bills, but it can also cause your system to overheat and burn out.

  • Dirty air filters hurt your health

A dirty filter allows dust, dander, and even mold to keep circulating through your home.

4.   Remove debris from the unit.

Over time, debris builds up on the air conditioner, reducing airflow, and decreasing system capacity. Debris includes things like twigs, pollen, leaves, and grass clippings.

To clean your unit, you’ll need the following tools:

  • Gloves and eye protection
  • Water hose with sprayer
  • Air conditioner coil cleaner

When you have these, follow the following steps.

Step 1: Turn off the unit. You’ll need to locate the circuit breaker or switch and switch it off.

Step 2: Use a water hose spray to clean any debris on the outside unit.

Step 3: Use the coil cleaner to spray the outside unit. Then, wait for around 15 minutes for the foam to bond with the dirt.

Step 4: Lastly, use a hose to rinse the coil cleaner off.

5.   Schedule regular HVAC servicing.

If you’re not yet signed up for regular HVAC servicing, now is the perfect time to get on board. Regular servicing will make the system work more efficiently and effectively throughout the year.

The following are the things that you should expect during an HVAC servicing:

  • The condensate drain will be examined for clogs.
  • If your unit is fueled by natural gas, the technician will check gas connections.
  • The thermostat can be checked and calibrated if necessary.
  • A new, good quality filter will be installed in the unit if necessary.
  • The unit will be thoroughly cleaned and checked for any biological growth.
  • Oil will be added to the motor oil ports.
  • Electrical connections will be examined for loose or corroded wires.
  • Gauges will be connected to the outdoor unit to ensure proper pressure and temperature.


Proper HVAC maintenance can improve the comfort of your home, reduce your repair costs and utility bills, and keep your family happy and healthy. On the flip side, a neglected air conditioner can cause costly breakdowns and premature equipment failure.
