Many facilities management teams adopt an “if it ain’t broke, don’t fix it” style. However, relying solely on deferred maintenance can leave your facility vulnerable to additional costs and lost productivity. Performing preventative HVAC maintenance ensures your facility runs efficiently and gives you peace of mind. 

If properly maintained, the hard-working components in your HVAC system will continue to perform for many years. However, if the system only works when a problem occurs, the components are likely to fail before the problem occurs.

What to do during preventative HVAC maintenance?

During a typical preventative HVAC maintenance visit, a trained HVAC technician will perform several inspections and take several actions, including:

  • Check the coolant level and check the system for leaks
  • Inspect, clean and straighten condenser coils to ensure proper airflow
  • Lubrication of moving parts
  • Check electrical connections and make connections as necessary
  • Replace or clean the air filter as needed
  • Check gas connections for leaks and make minor repairs if necessary
  • Test the thermostat to check if it’s working properly, including turning the system on and off

Although preventive HVAC maintenance is comprehensive, it takes little time to complete and does not interfere with business operations or home life. The technician completed the assessment and maintenance tasks efficiently and then hit the road, leaving the HVAC owner confident that his equipment was working properly.


How often is maintenance required?

The correct frequency of preventative HVAC maintenance depends on factors such as how big the furnace and air conditioning unit is, how often it is run, and more. A general rule is to have your system evaluated and serviced by a trained HVAC technician at least once a year. For systems located in demanding environments, frequent maintenance may be appropriate.

Another reason multiple visits per year can be beneficial is that it’s best to have your air conditioning system serviced before the hot summer months and your furnace serviced before the cooler nights and fall mornings arrive. Here are a few benefits of preventive maintenance.

Benefits of taking good care of your HVAC system

It pays to be proactive about the “health” of your HVAC system. But what exactly does it benefit a business owner or homeowner? Having a preventative HVAC maintenance program has many advantages, including:

Prevent costly failures. 

When a component of your HVAC system fails, replacement and repair costs can be high. Writing a check is especially difficult when you know that (often) the problem can vanish with regular maintenance or even a quick and cheap repair.


Reduce energy bills. 

An HVAC system not running efficiently is much more expensive than one at peak performance. Some may think that the cost of a maintenance program is a waste of resources, but our commercial HVAC maintenance team in Delaware can offset these costs with the savings we will realize on your energy bill. Maintenance planning and building operations require long-term thinking, and over time, the different components of your HVAC equipment will gain greater energy efficiency if maintained properly.

Extend the life of your system and its components. 

Like all mechanical systems, HVAC systems have a “life expectancy” and will eventually need to be overhauled and replaced. But if you could postpone that $5,000 bill for two years instead of paying it today, imagine its positive impact on your finances as a business or homeowner. Commercial HVAC systems are often one of the most expensive parts of a building, and you want to extend their lifespan. A routine preventative HVAC maintenance program offered by Service Unlimited is one of the best strategies for increasing overall system longevity. We’ll catch problems before they become problems and help you plan for any future expenses you may incur.

Enhanced comfort:

Installation of air conditioners and heaters is to make you more comfortable no matter the time of day. Likewise, your HVAC ducts distribute healthy air throughout your facility. A healthy commercial HVAC system in Delaware will provide higher comfort. Creating a comfortable work environment is our job; we’re the experts you need to maintain it.

Improve the air quality of your workplace. 

HVAC systems are planned to support a healthy and comfortable indoor climate. Regular maintenance of your system can help you achieve this goal. 

Workplace temperature directly affects employee work. A well-maintained HVAC system will be more beneficial to your business. Routine HVAC maintenance performed by a service provider like SUI also means one less thing to do on your end. You can focus on your business and let us worry about your HVAC system.

Reduce your environmental footprint. 

When your HVAC system runs efficiently, it uses less fuel, which is better for the environment. Additionally, as new technologies become available, your HVAC technician can further advise on ways to reduce your environmental footprint.

One type of air pollution that few people think about is indoor air pollution. Indoor air quality mostly affects your health and the health of others in the building. Air must be distributed and ventilated efficiently to provide your desired indoor air quality.

Warranty Check. 

HVAC system manufacturers usually require proof of annual maintenance when making a warranty claim. They may only accept your claim if you service your system at least once a year (preferably more).

Protect your home or business. 

HVAC systems are planned to operate safely, and they rarely cause damage to a business or home. However, they run on electricity, natural gas, and other fuels and can be dangerous if not properly controlled and used. Technicians must detect small leaks or other issues before they become big problems.

Preventative HVAC maintenance improves performance

preventative HVAC maintenance identifies problems quickly to improve the performance of your HVAC system. When an HVAC technician performs preventative maintenance on your system, they inspect each component for potential problems. When they find a minor problem, technicians quickly perform HVAC repairs before the problem gets worse. The problem identification aspect of preventative HVAC maintenance system problems from developing to requiring emergency HVAC service.



  1. I appreciate you informing us that while the correct frequency of HVAC maintenance depends on how big the air conditioner is and how often it runs, we are advised to have it serviced before summer and winter arrive. It’s almost spring in about a month or so, so I need to prepare to get my furnace at home checked for maintenance since we kept running it to keep the house warm. I’ll take note of this while I call an HVAC contractor in Richmond to hire for the HVAC maintenance I need at home soon.
