The refrigerant level in your HVAC system shouldn’t drop under normal conditions. This is because refrigerant isn’t used up or consumed – it simply moves through a sealed loop of copper tubing, absorbing heat as it goes through the evaporator coil, and releasing it outdoors via the condenser coil. If the refrigerant is escaping through an HVAC leak, a range of problems will develop, including: Higher Utility Bills As refrigerant leaks out, the HVAC system will have to cycle longer […]
It’s perfectly normal for your HVAC system to make some noise, such as a hum or a whoosh as air moves through the vents. However, an unnatural sound like rattling noise in ducts could be a sign of a problem. Let’s walk you through the common causes and solutions to rattling noises in an HVAC system. Debris in Outdoor Unit Sometimes the rattling noise carried through your ducts is actually emanating from your HVAC unit. If it’s originating from your […]
What’s a safe drain cleaner for your HVAC system and why would you need one? While a central air conditioner and a high-efficiency gas furnace produce cooling and heat, respectively, they also generate water as a byproduct of the process. All that liquid has to be drained away efficiently and effectively. A safe drain cleaner, along with regular annual preventative maintenance by a qualified HVAC service technician can help avoid HVAC clogs. Where Does the Water Go? Condensate produced by the […]
Thermostat communication has evolved substantially in recent years. For decades, the basic communication between thermostat and HVAC components was a simple four-wire system: power, furnace, AC, and fan. The simple concept provided on/off operation of the furnace and air conditioner based on an electromechanical switch that sensed temperature in a single room. As digital programmable thermostats came along, however, the wires became more numerous and the functions more complex in order to add automation and enhanced monitoring to your HVAC […]
