Commercial HVAC FAQs
A: The cost varies depending on your requirements. Call us today to discuss your HVAC problems and we will be able to give you a quote and schedule a visit.
A: SEER stands for Seasonal Energy Efficiency Rating. This ratio tells you high energy efficient your HVAC unit is. The higher the SEER, the more energy efficiency of the unit.
A: Businesses all over the world are increasingly turning to energy management systems to reduce the cost of heating and cooling their workplace. According to some estimates, over 35% of all US buildings with a surface area bigger than 100,000 square feet use energy management systems. This helps them save a tremendous amount of money on heating and cooling expenses. Even relatively smaller businesses operating from a medium-sized building can benefit from energy management systems. Simply put, an energy management system allows you to centralize all your energy-related decisions. Centralized timers and sensors are used to better control all heating, cooling, and ventilation systems. A typical energy management system has one terminal to tell you how much energy is being consumed at any point of time and where you could avoid wasting energy. The best part – you can access all these info from any computer using a secure web login.
A: Proper heating or cooling a commercial establishment is often an expensive operation. So much so that even a small difference in the energy consumption of your air conditioning and heating units can help your business save a lot on utility bills. Compared to the regular models, high-efficiency commercial HVAC systems can slash a huge chunk of your heating and cooling spending. Sure, they are also more expensive, but the initial investment can be easily recovered in the subsequent months because of substantially lower utility bills.
A: The size of an HVAC unit plays a key role on several fronts. If the unit is too small for your office, it will be unable to regulate temperature efficiently during extreme weather conditions. An inefficient system consumes more energy than it should, leading to fatter utility bills, among other issues. Similarly, if the system is too big, it will have difficulty reducing moisture from the air. This could make the air inside the office space humid and uncomfortable for your employees and clients alike!
A: A commercial HVAC system requires hefty investment sizing up to several thousands of dollars. Once you spend that kind of money, you can definitely expect your equipment to last as long as possible. The lifespan of a commercial HVAC varies depending on the brand and specs of the layout. However, on average, a well-maintained commercial A/C unit can last up to 10-15 years with the furnace, heat pump, boiler, etc. lasting anywhere between 15 and 20 years.
A: If your HVAC unit is more than 5-7 years old and needed excessive repairs in the past couple of years, but with little or no improvement to show for, you should consider replacing it. Even if you could somehow manage with the older unit by fixing the wear and tear from time to time, we don’t recommend it. Because, the older an HVAC system, the lesser its energy efficiency. Rather than spending on unnecessary expenses, such as higher-than-normal utility bills and repair charges, it is in the best interest of your company to put that money into a new system.
A: Most air conditioning manufacturers recommend regular maintenance of your commercial HVAC systems for a reason. Apart from prolonging the lifespan of the unit, regular maintenance also ensures round-the-clock optimal efficiency which is a must for any workplace. Ideally, you should have general maintenance done by experienced professionals at least once a year so they can conduct a thorough cleaning and optimize the system from the inside out. In the absence of regular maintenance, even a minor glitch could turn into a major issue over time and cost your business much more comparatively.
