Blower motor breakdown can be the result of anything from old age to failed bearings, high amp draw, electrical failure in the windings, dirt accumulation, and more. Knowing how to troubleshoot and diagnose problems with these motors is an essential skill an HVAC technician must possess.
Making the decision to open another location is no small undertaking and involves finding the right people to staff the new location and doing a lot of research to make sure the new area can support another HVAC business.
The survey, which collected data from nearly 18,000 small business owners from around the U.S., compiled answers regarding a community’s overall business friendliness, regulatory environment, new-hire prospects, and more.
As the popularity of variable-speed technology increases, many manufacturers are bringing new products to market to meet consumer and OEM demands. Here are a few of the latest HVAC motor-related products available on the market.
While older circulator pumps utilized single-speed motors and were largely inefficient, advances in motor technology, controls, and pump design have transformed the market and ushered in a new era of highly efficient products that feature variable-speed motors, easy installation and setup, remote connectivity, and more.
It’s very important to follow all safety procedures and retrofit guidelines when retrofitting a system with a refrigerant blend. By all means, never try to blend any refrigerants yourself because dangerous conditions and personal injury can occur.
Although it’s commonly acknowledged that there is no one-size-fits-all answer, natural refrigerants, such as carbon dioxide (R-744), ammonia (R-717), and the hydrocarbon (HC) refrigerants propane (R-290) and isobutane (R-600), have been garnering attention.
Frozen condensate occurs when condensation and exhaust gases generated from the heating process are discharged outside via a vent pipe and freeze in the cold air. If ice continues to build up, the vent pipe can become blocked, causing the furnace to shut down.
The Nov. 19 publication of the NOPR tentatively ends a one-year period of uncertainty for the HVACR industry, which adapted as best it could to the new energy conservation standards in the absence of enforcement guidance from the DOE.
