The Benefits of Periodic HVAC & Plumbing Maintenance

Plumbing and HVAC systems are necessary for the comfort and safety of your commercial space, but it’s easy to overlook when they need maintenance. Regular maintenance ensures you get the most out of your equipment and keeps your space comfortable and safe throughout all seasons, saving you money in the long run by avoiding emergency repairs.

These are just some of the benefits of commercial HVAC and plumbing maintenance from a bonded and insured company that’s been in business since 1964.

Extend the Life of Your Equipment

When it comes to keeping your commercial building operating at its peak efficiency, there’s no room for error. The cost of replacing malfunctioning equipment can add up fast; if your heating system goes out during a cold snap, it’s not just inconvenient — it could also take a serious toll on your bottom line.

To avoid these problems, consider investing in preventative maintenance. Taking care of your building’s core systems can help extend their life span, saving you time and money in the long run.

Avoid Costly Breakdowns

Frequent maintenance can help prevent costly breakdowns and improve your building’s energy efficiency. Commercial buildings make up a significant portion of an organization’s total expenses, so keeping these structures in good working order is vital to maintaining a solid bottom line.

Commercial HVAC systems are essential because they control temperature, humidity, and air quality for employees, customers, and visitors. If your commercial building has central AC or heating problems during hot or cold seasons, you could lose valuable business opportunities or face expensive lawsuits from disgruntled customers harmed by extreme temperatures in your facility.

Protect Your Investment

Keep your heating, ventilation, and air conditioning (HVAC) systems running smoothly with routine maintenance. Not only does regular servicing ensure your system is operating correctly, but you may even qualify for tax breaks by doing so. As with any investment, a little TLC goes a long way. You can also add value to your property by implementing green plumbing practices.

Reduce Energy Costs

Regular maintenance will help you catch any issues before they get worse or more expensive to fix. If your ductwork or plumbing is leaking, it can be fixed sooner rather than later. A leaky air duct in a commercial building can waste up to 30% of heating and cooling costs through energy loss.

The longer you wait, the higher your monthly energy bills will become. Regular maintenance can save energy costs while keeping your business safe from major catastrophes like water damage or fires caused by outdated systems.

Keep Your Commercial Property in Good Shape

Like your home, it’s essential to keep your commercial property in good shape. If you have a plumber or HVAC technician you trust, consider having a plan to cover these central systems.

When choosing what type of maintenance plan is right for your business, there are many aspects to consider, such as the age of your equipment and where it’s located in your building. The size of your business also plays a role in determining which type of maintenance program is best for you.

The most common types of HVAC and plumbing issues in a commercial building are:

  1. Dirty filters: This is an easy fix that can be done by your maintenance staff or can be included in your HVAC maintenance plan. The good news is that dirty filters don’t damage your equipment, but they’ll directly impact your energy bill if they’re not changed regularly.
  2. Leaking water lines: If you have a leak in your plumbing, it’s usually not a good idea to try fixing it yourself. When there’s a leak in your plumbing system, there is usually an issue with one of your pipes that needs to be fixed immediately before further damage occurs.
  3. Dirty coils: If you have a dirty coil, it can make your system work harder than it needs to in order to cool or heat your building. This will cause your energy bill to go up, which no business owner wants during these tough economic times.
  4. Faulty thermostat: A malfunctioning thermostat can make your system run inefficiently, resulting in higher energy bills. The good news is that faulty thermostats aren’t expensive to replace and are easy to install.
  5. Leaking water heater: A leaking water heater could be a disaster waiting to happen if you don’t take care of it right away. You should never try to repair a leaking water heater on your own because there’s too much risk involved.
  6. Low refrigerant: Refrigerant is an integral part of your air conditioning system, so you need to ensure it’s at a proper level before it can cool your building effectively.
  7. Faulty motor: Your AC system relies on a good motor to work correctly, so you need to ensure it’s in good working order before turning it on.
  8. Clogged toilet: Stubborn clogs can occur in any building, but it’s especially common in commercial buildings because so many people use them daily.
