The company I work for needed all three evaporative coolers replaced about four months ago. We searched around for a company that offered replacement parts for these particular coolers but they were so old that new parts were not an option. So we had to start getting quotes for brand new coolers.
Long story short, Liberty Cooling and Heating beat out all other prices that were offered and we ultimately opted for their services.
Now jump ahead to the day of delivery and installation. They showed up at about 6:30 in the morning and were completely finished around 9am. They removed the old coolers and installed the new ones in record time. This was most likely because it wasn't just a 2 or 3 man crew. I would estimate there were at least 10 to 12 workers present which lead to a quick and timely install.
The coolers and still working great although its finally cooling down and we won't need to use them again until next summer.
If you have any heating or cooling problems I would definitely recommend this company.
