You know the noise. It's the kind of noise that's been grating your nerves for three weeks, but who cares as long as the front office is nice and warm and nobody has complained? That's just how it goes when businesses with commercial HVAC systems in Central Illinois don't plan out their replacements. One odd noise leads to an odd smell, which leads to odd temperatures, and before long a contractor is on the scene to find out the unit is just days away from completely dying. I've been inside more buildings than I care to count where the owner shrugged off the oddities as normal because "it's been that way for a few years".

Age Matters More Than You Think

Most commercial systems are designed to run between 15-20 years in general with the proper maintenance. But, a unit doesn't just stop functioning after year 15. Typically it comes to a point where the costs for repairs, bills for energy, and the overall cost of upkeep outweighs the value of the unit. If there's a possibility that the unit could be entering this range, it's definitely recommended to have it looked at by a professional rather than forgoing maintenance or repairs altogether.

Energy Bills Tell A Story, If You Listen

When I ask business owners if their bills have gone up, even with roughly the same usage, 9 out of 10 times they say yes. Often these businesses aren't concerned by this fact either, citing the rising cost of energy as the reason for the increase. While some of these claims are completely valid, there are some systems that simply have to work harder than they should to make up for a variety of different issues. Over time, these issues compound and before long the bills have gone up significantly. In many of these cases, the unit is well beyond the recommended replacement period.

When Comfort Comes Into Question, Don't Ignore It

Whenever the discomfort of staff or customers starts to peak, it's a good idea to take notice. While there are plenty of reasons for discomfort in a building, one that's consistently too hot in some parts and too cold in others is an issue for the system. In many older buildings in Central Illinois that have had additions or renovations, their system wasn't made for the building they're in now. Sometimes the issue is surprisingly simple, sometimes not so much.

Repairs Start Piling Up Faster Than You'd Like

There comes a point when the system you have isn't one you're maintaining on a regular basis, but rather one that you're constantly repairing. When repairmen are called more frequently in a shorter time span, or one repair costs significantly more than the one before it, it's usually recommended to have the unit looked at for a possible replacement. One rule of thumb that many technicians will use (often not officially) is to get a new unit anytime a repair costs over 30 percent of what a replacement would. While I know it's not pleasant, keep in mind that it's far better to throw your money into a system that will keep working rather than one that won't.

Air Quality Issues Show Up Quietly

Often these issues are easily overlooked in favor of others, but if there are concerns about dust, stuffiness, or the overall quality of the air inside your building, it's a solid idea to invest in checking out your system. Many issues that arise in commercial HVAC systems tie into air quality, from the filters to the ducts to the unit itself. The majority of systems that make people feel ill or uncomfortable are ones that weren't designed to function to capacity.

Maintenance Records Are More Useful Than People Realize

If there happens to be a maintenance log with your unit, it's probably a good idea to look it over. While some people tend to keep good logs without the recommendation of a technician, others might find that simply skimming over the records is enough to spot an issue. In the end, the reason for those logs was to spot problems before they became ones, so use the information you're already paying for.

Building Changes Change The Math Too

If there have been any renovations, additions, or significant changes to the amount of space used or what's going on, it's a good idea to have the system evaluated for its effectiveness. Any changes that have been made to the building could require a different sized unit, even if what you have was adequate before. This is another one of those issues that can be easy to overlook, as it's gradual. You don't necessarily notice the system struggling until it's right in front of your eyes, either because it's a hot summer day or the middle of winter.

All in all

There's nothing to say that any of these issues mean you need to replace your unit immediately. However, if you're experiencing a combination of problems and want help understanding your existing system and your options for the future, it's worth having a qualified professional take a closer look. A good HVAC contractor should be able to evaluate your building's system, explain its condition, and discuss practical options based on your property's needs. The weather in Central Illinois is harsh enough without having to fight the elements, so staying ahead of potential HVAC problems can help reduce unexpected disruptions.
