Scheduled Maintenance

The best way to avoid costly repairs, or total failure of your HVAC unit, is to have routine maintenance performed. This is an important investment that all business owners should make. Chances are this will save you money in the long run.

Due to the climate in Southern California during the summer months, your air conditioning unit can consume up to half of the energy your commercial building consumes. Keeping your employees and visitors comfortable is important, making it imperative that your HVAC unit is performing at optimum efficiency.

The EPA suggests that you have your unit serviced and inspected at least twice a year. We recommend you have this done before the cooler months and before summer, so that you are prepared for any extreme weather events.

Repairs and Emergency Services

Commercial heating and cooling systems are designed to handle larger loads, meaning they are much stronger and more durable than your typical residential air conditioning and heating systems. While they last longer, it doesn’t mean that you will not encounter an occasional problem.

As can be expected, when there is a problem it will likely be larger and more expensive than a residential unit. No business can afford any downtime due to intolerable conditions. This is why scheduled maintenance is so important. The earlier the problem is discovered and rectified, the better.

Some of the most common issues our commercial clients experience are:

  • Thermostat problems. There are various reasons why a thermostat may act up. Commercial buildings that have zone control systems can commonly have problems with different areas. This is something that should be handled by trained technicians that understand these types of complex systems.
  • Unbalanced temperatures. Uneven temperatures may occur for a few reasons. The most common reason is when the HVAC unit on the building is not the correct size. If your system is incapable of heating or cooling the square footage of the building you will notice areas that are not receiving air.Montclair HVAC

Problems with the duct work, such as being damaged or becoming dislodged will also cause spotty temperatures. On occasion the problem will be with the thermostat, especially those that are set up on zone control.

  • Fan damage.This is one of the more common reasons for HVAC problems that we see. The condensing fan motor endures extreme temperatures and elements throughout the year, as it is virtually exposed.
  • Dirty equipment.Dirt and other debris can cause major damage to your system. These particles often accumulate in the condensing coil of the air conditioner resulting in reduced efficiency and capacity. When the coils are extremely dirty, you will notice the unit starting to freeze up. This ice maybe seen on the copper lines on the inside or outside of your unit.
  • Low coolant.This can be caused from a leak or just from everyday use. If you get your regularly scheduled routine maintenance, running out shouldn’t be an issue. A few signs that your system is low on refrigeration are: blowing hot air when thermostat is on cool, spike in electric bill, coils are frozen, or the area takes forever to cool off.
