  • Make sure you return and supply registers are free of obstructions, such as furniture and drapery. Insure your supply registers are all fully open. On hi-Velocity heating & cooling systems, closing a register does not force air to other registers. Once you close a register the EMC motor on the air handler automatically adjusts and delivers air to the open registers. Therefore, you essentially will lose the air flow that was coming out of the register you closed.

  • By setting your thermostat fan switch to the ON position, you will be utilizing the fan on your furnace to circulate the air throughout your home. This will circulate the air in your home even after the air conditioner is satisfied; making it a move even temperature throughout.

    Air conditioning has many uses besides keeping us comfortable. Many industries depend on it to keep the air in their plants clean, cool and at the right moisture level. For example, textile fiber such as wool and cotton will stretch or shrink as the moisture content of air changes. This causes variations in the quality of the cloth. Too much moisture in the air -or even on a worker’s fingertips- will cause delicate metal parts such as rocket components or precision instruments instrument to corrode. The wrong temperature can spoil a batch of antibiotic culture. Proper air conditioning prevents this mishap.
