Are you ready to start the process of replacing your rooftop HVAC unit? If you answered yes, you may be waiting until spring because you’ve been told no HVAC work can be performed until the outside temperature reaches a certain point. While that’s true, the process of getting an estimate, looking at your budget, choosing the right equipment and getting it installed can take months. This means that if you wait until early May to start contacting commercial HVAC contractors for estimates, you may not receive your new unit until the end of summer.
With autumn temperatures cooling off and winter on the way, it’s important to start thinking about fall chiller cleaning and winter shutdown. Properly cleaning and taking your chiller off-line prevents harmful bacteria and containments from building up in the chiller tank and making themselves known in the spring when you reactivate your system. Here at Althoff, serving Chicago, we want to make sure you know the proper steps to take and the reasons why your chiller should be professionally shutdown in the fall.
When is the last time you had the plumbing system in your Chicago building inspected for water leaks? For most commercial and large residential buildings the answer may be months or years ago minus a few repairs for obvious water leaks. The truth is that large buildings in Chicago should have their plumbing systems inspected for leaks and partial or full clogs at least once a year and preferably twice a year for buildings that have heavy water usage. Having your Chicago building’s plumbing system inspected twice a year can catch common problems, including, pinhole leaks, running toilets, leaking faucets and problems with drain and sewer lines before they cause a catastrophe. Here are some of the common water problems we diagnose and repair in the commercial and multi-story residential buildings in the greater Chicago area.
With the end of summer rapidly approaching and the eminent onset of fall, you may be thinking about switching your HVAC system from cooling to heating, but is it ready? When it comes to ensuring that your commercial HVAC system in Chicago is ready for fall and winter, one of the best things you can do is schedule a fall inspection, which helps ensure there are no excessively worn parts and usually includes an interior and exterior cleaning of the system.
Properly maintaining your HVAC system can keep your heating and cooling bills low and extend the useful life of your unit. In order to complete all the preventative maintenance tasks needed for your commercial HVAC unit in Chicago, you’ll need to have a maintenance checklist. If you aren’t sure where to start, we recommend starting with ASHRAE’s Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems, which will give you a list of quarterly, seasonal and yearly HVAC maintenance tasks. If you aren’t sure what types of preventative maintenance your HVAC unit needs, we would be happy to help you create one and perform all the needed preventative maintenance.
Have you noticed a decrease in the amount of heat produced by your boiler and/or radiators? If you have, it could be due to a faulty circulator pump, which is responsible for circulating the hot water from your boiler to your radiators and back to your boiler. Thankfully, there are some things you can check to determine if is it your circulator pump and if you need to call a professional, like the HVAC technicians at Althoff, serving Chicago.
It may come as no surprise that all buildings in Chicago need periodic maintenance in order to prevent health and safety issues, reduce the risk of equipment failures and to keep the occupants and visitors comfortable. The difference is in how that maintenance is performed. Ideally, every building would practice preventative maintenance, which seeks to locate and identify equipment problems before they result in catastrophic failures. However, some buildings practice a type of maintenance known as deferred maintenance, usually due to budgetary problems. Unfortunately, deferring maintenance to a later date can actually result in an increase in building expenses.
How comfortable is your Chicago building? According to ASHRAE, a building has achieved optimal thermal comfort when a minimum of 80 percent of the occupants are satisfied with the indoor environmental conditions, but how do you determine if 80 percent of the individuals in your building are comfortable? This can be a tough question to answer. Thankfully, there are factors you can consider when it comes to improving the indoor comfort of your building.
