HVAC units, whether used for cooling, for heating or for both, are complex, high-capacity pieces of equipment that take experienced technicians to maintain and to repair. Here are a few of the situations that require the attention of an HVAC expert:The unit stops working – if your HVAC equipment stops working, even though the thermostat is set properly and the unit is switched to the desired operation mode (heating or cooling), call an expert right away.The heat pump delivers cold air – if this happens, check whether the outdoor unit is not covered in ice or snow. If you don’t find any such problem outside, call a technician to check for the cause that led to the problem and to fix the unit.The unit does not cool the room the way it should – if your room is too hot, even though the AC runs on full capacity, check and clean the filters. If the problem persists, make that service call because the issue might be caused by the fault of the thermostat, of the motor fans or of the compresso…

The basic concept of air conditioning was invented and used by the ancient Egyptians who used who hung reeds kept moist with water trickling from above on windows to keep the air inside cool and kept, while the Romans used aqueducts installed in the walls of buildings to keep the walls cool with the help of circulated water.The very first modern air conditioner that used electrical cooling was invented much later, only in 1902, by Willis Haviland Carrier, an American engineer and inventor. Initially, Carrier wanted to put together a machine that could control air quality and temperature in the printing plant where he was working to prevent changes in paper dimensions and to keep ink in place on the paper. The invention became so popular that Carrier soon opened his own air conditioning company to meet the increasing demand.Carrier’s air conditioner was first used in production plants and, by the 1920’s, the invention became used in residential units and it spread to the Sun Belt as we…

Innovations in the HVAC Industry
