If you have a central air conditioning system or a forced-air heating system, your HVAC equipment plays a substantial role in your home's indoor air quality. With a well-sealed and insulated home, your HVAC system is arguably the most critical element in your overall air quality. Many air quality issues, such as mold or unusual smells, come down to poor HVAC maintenance or equipment. Fortunately, you have plenty of options for keeping your home's air fresh and clean.

Why Is Your Walk-In Refrigeration Unit Triggering Its Low-Pressure Control?
The low-pressure control switch is critical for many commercial refrigeration systems, including walk-in coolers and freezers. This switch usually contains two separate settings adjustable by an HVAC technician. The first setting determines the system pressure that allows the compressor to cut in, and the other setting determines when the system should shut down for a low-pressure condition. An undercharged system can result in compressor damage just as easily as an overcharged system, so it's essential for the low-pressure cut-off to function correctly and accurately. [Read More]
When Should You Worry About A Noisy Furnace?
Modern furnaces are relatively quiet. There are three sounds you'll typically hear from a furnace that's operating correctly: the draft inducer, the house blower, and the burners. Most of these noises should be inaudible unless your furnace is close to a living area or you're standing right next to your HVAC equipment. Of course, all HVAC equipment can get noisier as it ages. If you hear some unusual sounds from your furnace, this guide will help you separate noises that aren't a big deal from ones requiring closer inspection. [Read More]
Signs A Capacitor In Your HVAC Is Bad And How The Problem Is Fixed
You may know that electric motors need more power when they start than they do when they're running. This is true for the motors in your HVAC too. That's why the fan motor in the condenser and the blower motor in the furnace have capacitors. Capacitors store energy, and they provide the extra power the motors need to start up and get running. When a capacitor goes bad, it can have different effects on your HVAC depending on if you're running the AC or furnace. [Read More]
