Should I replace an older unit even if it seems to be working fine?
It’s probably a good idea. Commercial air con systems that are older than 15 years will start to show signs of significant wear. If you chance it, you could start to pay for repairs that, over time, become more and more costly. If you are not experiencing issues now, you can use the time to research installers and systems with the latest technology. Today’s systems are also much more energy efficient than older models, so it’s likely that you will save on your utility bills with replacement.
Do the different parts for my commercial AC system need to match?
It can depend on the part. If you are under warranty, you’re likely to receive matching parts from the manufacturer and don’t have to worry. Many components in commercial systems are cross compatible with each other or sized to standards. But going with parts that match will help with efficiency and performance. A small wait for an ordered part might be worth it over the long term.
Is poor air balance considered a commercial air conditioning repair?
It can be, although the concern will be less on the few offices or rooms that are warmer than others and more on what is causing the issues in the first place. A technician will want to check whether there are issues with blowers, dampers, or ducts that can affect efficiency or cause the whole system to overwork itself.
Can you repair a leaking coil or does it have to be completely replaced?
Most of the time, an evaporator coil will spring a leak when it develops holes caused by corrosion. This starts with buildup that eats away at the metals inside, usually putting them beyond repair by the time they are detected by way of water seepage. It’s also worth noting that the cost to patch or repair the coil could be nearly the same as the price for a brand new one that will last longer and come with a warranty. For these reasons, a technician will typically recommend replacing this part of your commercial air con system.
Is replacing lost refrigerant considered a repair?
While the refrigerant itself isn’t technically damaged, there’s probably an underlying reason as to why the system has less refrigerant than it should. Finding the resolution for that issue is definitely a repair. Refrigerant does not evaporate, dissolve, or dissipate on its own over time. If your commercial air conditioner is not putting out cold air, any missing refrigerant has leaked out. The technician will want to find the leak, clean up the unit, and replace the faulty parts. It’s worth noting that most refrigerant leaks happen in faulty evaporator coils, so any commercial air conditioning repair service will include replacing the coil and topping off the refrigerant.
