If you plan to open a pub, restaurant, cafe, hotel, or a grocery shop, you need to understand how commercial refrigeration works.
AC units can make up for more than half of your utility bill. Fortunately, there are some ways of curbing down electricity costs.
Following basic refrigeration maintenance tips will help to keep them running smoothly and efficiently in between service checks.
If your AC is not working, or the system is blowing warm air, or the unit shakes or makes strange noises, then most probably your AC compressor has issues.
