This decibel (dBA) table compares some common sounds and shows how they rank in potential harm to hearing. In many industries, workers are exposed to dangerous noise levels. This is particularly true in the construction, lumber, mining, steel and textile industries.
Since the sensitivity of the ear to sound is not the same for all frequencies, weighting or attenuating filters are included in the sound level meter's circuits to simulate the ears' response.A noise level meter gives an instantaneous measurement of the noise present, but cannot measure the duration of the exposure.

Most air conditioners have their capacity rated in BTUs, or British Thermal Units. A BTU is, generally, the amount of heat required to raise the temperature of one pound of water one degree F. Specifically, a BTU is 1,055 joules, but the first definition is easier to understand in real-life terms. One "ton", in heating and cooling terms, is 12,000 BTUs.

Grenz Service Co. installed a new boiler system at our Lodge. Jim Grenz presented our group a recommendation on which system would be a good fit for our building and needs. Once we decided to move forward he was able to place a hold on the new boiler with the manufacturer during a time of short supply. The Grenz crew was able to remove the old boiler and installed the new system in one morning. Everything was handled very professionally and the system is working great! Jim made himself available to answer all our questions before and after the installation. It couldn't have been any easier!

We’ve been customers for two years now. Very happy with our annual service of our furnace and A/C. Bill has been our tech. Always personable and informative. You can tell he takes pride in taking care of his customers. He takes the time to do the job right and values his customers money as if it were his own. I highly recommend Grenz without any hesitation.

I would definitely recommend Grenz. I had a company come out and state I needed over $1000 in repairs to my air conditioner and highly recommended I replace my system for over $10,000. So I called Grenz for an estimate and a couple hundred later all is working perfect. They saved be big money and were 100% honest. Honestly is so hard to find now-a-days but I found it with Grenz.
