Commercial HVAC preventative maintenance checklist


Here’s a general task list to use as a reference when comparing commercial HVAC preventative maintenance contracts. But before we get into the details, here’s an important thing to remember: your plan should be customized according to your needs. Depending on the age and condition of your equipment, your location and usage, and the size and type of equipment you have, more tasks or different ones may be needed. For example, if you have a water-cooled system, you have a chiller and/or a cooling tower that requires maintenance. Or if you have a combined heat pump or VRF system that provides both cooling and heating, you have different components that require inspection and adjustment, so call Air Speed Heating and Cooling and we can help!

Commercial HVAC Maintenance FAQs

How often should commercial HVAC be serviced?

Your business depends on your HVAC system. It is imperative that you have a working system in place. The right maintenance schedule will ensure that your system operates efficiently and effectively.

What does “commercial” mean when it comes to HVAC?

A commercial HVAC system is one used in a building or facility where people work, live, eat, sleep, etc., such as a hotel, restaurant, office building, school, hospital, factory, warehouse, retail store, etc.

Why do I need to maintain my HVAC system?

A properly maintained HVAC system helps prevent costly breakdowns. Regular maintenance ensures that your system runs smoothly and efficiently, saving you time and money.

When should I call a professional for HVAC maintenance?

If you notice any unusual noises coming from your equipment, or if your system has been acting up lately, then it may be time to call a professional.

What is a typical maintenance schedule for a commercial HVAC system?

A good rule of thumb is once every three months for smaller buildings, and once every six months for larger ones.

Do I need to pay extra for a yearly inspection?

Yes. Many companies charge extra for this type of service because they want to make sure everything is in tip-top shape before they start charging you for their services.

What is commercial HVAC preventive maintenance?

Preventive maintenance is an important part of keeping your HVAC system running well. A technician will inspect and clean your system regularly to detect problems early so they can be resolved quickly and easily.

How does HVAC work in a commercial building?

The heating aspect of a commercial building’s HVAC system is usually produced by using radiators and/or supply air systems. To ventilate a building, you must extract contaminated air from it while maintaining clean air. It also helps circulate the internal air and remove any excess moisture.

What are the different types of commercial HVAC systems?

There are many different types of commercial H V AC systems available today. They all serve to provide heat and cooling for commercial buildings. Here are some of the more common types:

Radiators – These are large metal boxes filled with hot water or steam. They are used to warm up rooms and spaces.

Supply Fans – This is the fan that blows air into the room through vents.

Return Fans – This is the opposite of the supply fans. It pulls air out of the space and pushes it back into the ductwork.

Duct Work – This is the pipe that carries air throughout the building.

Air Handling Units (AHU) – This is the box that houses the blower motor and filters.

Blowers – This is what moves the air around.

Refrigeration – This is how we cool things down.

Condensing Unit – This is the unit that converts the refrigerant gas to liquid form.

Evaporator Coil – This is the coil inside the condensing unit that turns the refrigerant gas into liquid form.

Evaporation Chamber – This is where the vaporized refrigerant goes when it leaves the evaporator coil.

Capacitor Heater – This is the device that heats the compressor oil.

Compressor – This is the machine that compresses the refrigerant gas.

What are the 3 main types of refrigeration systems that are used in commercial building HVAC systems?

In most cases, there are three main types of refrigeration units that are used in commercial HVAC systems:

1. The traditional split-system air conditioning unit.

2. The newer variable speed air conditioning unit.

3. The newer variable refrigerant flow air conditioning unit.

Which one should I use? That depends on the size of your building and its location. If you have a small office building, then the split system might be best. For medium-sized businesses, the variable speed air conditioner may be better suited. Finally, if you have a larger business, then the variable refrigerant flow air conditioner would probably be the right choice.

What is the difference between residential and commercial HVAC?

A commercial HVAC system is designed differently than a home HVAC system. Commercial HVAC systems are much bigger, heavier duty, and require more energy to operate. They also need to be able to handle extreme weather conditions like high humidity and low temperatures.

The two main differences between residential and commercial H VAC systems are the size and weight. A commercial HVAC system will weigh at least 1000 pounds, and can easily exceed 2000 pounds. In addition, they will generally be about 4 feet wide by 8 feet tall. Residential HVAC systems are usually smaller and lighter, weighing less than 500 pounds, and measuring approximately 2 feet wide by 5 feet tall.

How often do I need to service my commercial HVAC system?

There are many different factors that determine how often you should service your commercial HVAC system. Some of these include:

• How old is the equipment?

• What type of equipment is being used?

• Is the equipment located outdoors or indoors?

• Does the equipment run 24 hours a day?

• Are there any special circumstances such as extreme heat or cold?

• Do you have an emergency generator?

• How large is the building?

If you answered yes to all of the above questions, then you should schedule regular maintenance for your commercial HVAC equipment. It’s important to check the equipment every month, but especially during the summer months.
