Hydronic pumps are a critical part of your commercial HVAC system’s operation, keeping your building cool in summer and warm in winter. Here are some of the most common problems with this unit that we’ve dealt with at our  commercial HVAC company in NJ,  and how to solve them. Cavitation:  This occurs when there is too much air in the liquid that flows through the system and can lead to increased wear-and-tear of the pump and damage to the impeller. Vibration: Excessive vibration can be caused by out-of-balance equipment, bad bearings, an unbalanced rotor, bent shaft or a clogged impeller. The pump will have to be checked as it may have worn out, or your system will require lubrication, replacement bearings, impeller adjustment or an adjustment of the flow speed. The pump is too big: HVAC equipment is often selected without considering the size of the area the system is servicing. An oversized pump will start up and shut down more than it is designed to do beca...

Looking for a  commercial HVAC contractor  to maintain, repair, design or install a new HVAC system for your building? Here’s some advice to help you find the right team for the job. Don’t Make These Mistakes When Hiring a Commercial Contractor  You don’t know what you need:  Of course, your HVAC contractor should be able to do a full assessment of your system and advise you on repairs or upgrades, but it’s important that you have an informed idea of the services you are seeking. Are you making energy-efficiency a priority? Is your system making strange noises and emitting unpleasant smells? What is your budget? You don’t get multiple quotes:  Unless you have industry experience, it’s very difficult to tell when a quote is reasonable or not, which makes getting multiple quotes essential. Call in at least three contractors and have them assess the situation and see what they offer before you accept an estimate. You don’t ask for references:  The...

In the USA, commercial buildings account for a massive 19% of the total energy consumed in the country – primarily for heating/cooling and light – with office, retail, educational and healthcare buildings at the top of the list for consumption. One of the most significant opportunities for commercial buildings to reduce their consumption – and therefore their running costs – is the implementation of energy-efficient HVAC systems. Here’s a quick guide to energy efficiency ratings for your heating system or  boiler system  from commercial heating systems specialists. Energy-Efficiency Regulations for Commercial Heating Systems and Boiler Systems  In heating systems, efficiency is measured by Annual Fuel Utilization Efficiency (AFUE), which measures how effective the equipment is in converting fuel into heat. In a 90% AFUE commercial boiler, for example, 90% of the fuel consumed by the boiler is turned into heat, so the higher the rating, the more energy-efficient t...

Owning or operating a building with old HVAC systems comes with a wide range of expenses and responsibilities, especially when it comes to repairs and maintenance from commercial HVAC contractors. The cost to replace HFC refrigerants is substantially higher than the newer refrigerants. The Cost of Harmful Refrigerants is Higher Than You Think, Say Commercial HVAC Contractors  Old refrigerants and prohibited refrigerants aren’t just harmful to the environment – they’re targeted by EPA policies that carry stiff fines for businesses and HVAC contractors not conforming to new regulations. These old refrigerants are classified as Ozone-Depleting Substances (ODS), and as such are regulated as Class I or Class II controlled substances. R-22, for example, is a Class II controlled substance as it contains hydro chlorofluorocarbons (HCFCs). This and other old refrigerants are currently being phased out and will become illegal on January 1, 2020. How Can Old Refrigerants be Safel...
