As the weather begins to cool, now is the ideal time to begin prepping your HVAC system for autumn. To keep your building warm throughout the season and into winter, your HVAC system must be in good working order. Set aside some time to evaluate the heating-specific systems and ensure that everything is operating properly. Follow these autumn maintenance suggestions to ensure your HVAC system is ready for the colder months ahead.

1. Continue routine preventative maintenance.

Due to wear and tear, many commercial HVAC systems lose efficiency over time. Electrical failures, dust collection, worn-out components, a lack of lubrication, and malfunctioning compressors are some of the most prevalent issues that reduce energy efficiency

Many businesses, incorrectly, only take corrective measures after the HVAC system fails – instead, we advise that firms should do frequent unit inspections. This way, before the cold winter arrives, you can identify, avoid, and correct any possible problems. After a given amount of time, most components in a commercial HVAC system must be examined, maintained, and even replaced. When possible, remanufactured spare parts and components, such as compressors, should be used for preventative maintenance. A standard check-up should include the following:

  • Thermostat settings
  • Electrical connections
  • Lubrication of moving parts
  • Condensate drains
  • Controls

Carrying out preventive maintenance can save you up to 40% in energy costs as well as future repair costs.

2. Cleaning air filters.

When was the last time you had your air filter cleaned? Your air filter should be replaced every 1-3 months. So, if you haven’t already, the start of a new season is the ideal moment to do so. Most importantly, if the air filter isn’t operating properly, your entire HVAC system might suffer.

Cleaning your HVAC filters on a regular basis offers numerous advantages:

  • Maintain clean air that is free of allergies and dust. This is especially important for those who suffer from allergies or respiratory problems like asthma. Dirty air filters will transport dust and allergens throughout your property by circulating them via your HVAC system.
  • Reduce energy expenses. Clogged and dirty HVAC filters force your heating and cooling system to work harder to move air around the building. The harder your system has to operate, the greater your monthly energy bill. Maintaining your HVAC filters on a regular basis can help you save up to 15% on your electricity expenses each year.
  • Extend the life of your HVAC system. The most common cause of heating and air conditioning system failure is a clogged filter. When the filter becomes clogged, your system needs to work harder, which can lead to overheating. If the damage is severe enough, you may be required to purchase new HVAC equipment.

3. Check heating-specific parts.

It’s also a good idea to check the following heating-related equipment and processes:

  • All gas/oil connections
  • Gas pressure
  • Burner combustion
  • Heat exchanger

If the connections aren’t in good working condition, they might cause a fire and jeopardise the health and safety of the whole office. It is also critical to ensure that the burner is clean and that the heat exchanger is not damaged. Take care of these concerns before turning on the heat.

4. Clean up after the summer.

HVAC systems exposed to the elements may show signs of wear and tear after the summer. To remove any bird droppings, use a strong cleaning solution, such as a bleach and hypochlorite solution. You should also clean up the surrounding area, remove any debris, and double-check that everything is secure.

5. Investigate sounds and smells.

Have you detected an unusual odour? Have you heard any unusual sounds? If the HVAC system does not sound or smell as it should, there might be an underlying problem. Try to identify the source of the problem and resolve it in time for autumn.

6. Don’t forget to check…

Don’t overlook the ducts, fan, blower motor, and safety controls when checking the HVAC system. It’s also important to clean essential components such as the blower assembly, ignition system, and evaporator coil. Keep an eye out for leaks as well.

7. Replace the system, if necessary.

If you are dissatisfied with the findings of your examination, you should think about replacing the entire HVAC system. The system needs to work more to ventilate and heat the workplace when the weather grows cooler. As a result, if it’s not operating properly, you might face severe implications later on.

8. Choose the right equipment.

If you need to replace your HVAC system or are building a new office, you must ensure that the unit you choose is the correct size. Units that are excessively large are inefficient, whereas tiny units operate continuously and cannot keep up with the workload. Before you buy, make sure you can identify the correct load capacity for the furnace and air conditioner.

9. Schedule your routine maintenance/tune-up before winter.

To help maintain your commercial HVAC system working safely and effectively, we recommend that it is examined twice a year. Autumn is an ideal time to plan your maintenance, as you can beat the crowds and take care of any concerns before the cold weather sets in.

Routine HVAC maintenance has several advantages:

  • Improved air quality
  • Increased energy efficiency
  • Identify potential safety hazards
  • Prevent unexpected repairs and costly breakdowns
  • Extend the life of your commercial HVAC system

The specifics of your maintenance checklist will vary based on your system. A typical HVAC maintenance/tune-up could include the following:

  • Inspecting all moving components, burners, blowers, and belts
  • Changing filters as needed
  • Lubricating blower bearings and motor
  • Checking and tightening electrical connections
  • Cleaning condensate drain, trap, and pan
  • Cleaning heater, evaporator, and condenser coils
  • Measuring refrigerant pressure
  • Measuring gas pressure

10. Consider an annual maintenance plan.

Running a business can be very time-consuming. Between 12-hour days, family time, and the sliver of time you set aside for yourself, there aren’t many spare minutes or hours to consider your HVAC system. Fortunately, there is a workable option. You won’t have to worry about arranging maintenance with the help of an annual maintenance plan. Instead, one of our trained experts will come out to your home and service your system at no extra cost. All you have to do is pay an annual fixed cost, which includes priority service and savings.

With these commercial HVAC recommendations, you’ll have an efficient, healthy system that will keep you comfortable without costing you a fortune. For installation, maintenance, and everything else, give us a call on 01375 893892.
