5 HVAC Frequently Asked Questions

Why is my HVAC unit making noise?

It is normal for your heating and cooling equipment to generate some noise when operating. There are a few factors that influence its sound level, including age and insulation. Hearing unusual or loud noises, on the other hand, might indicate an issue with your system. If you don’t address it, there might be major and costly implications when left unattended.

Why is it important to have my comfort system maintained regularly?

For sure, you wouldn’t purchase a new car and expect to never have to pump the tires, change the oil, or investigate strange noises. Your home comfort equipment is similar to a car engine. It’s a machine that includes a motor, electrical components, and even fuel. As a result, it’s critical to have an expert professional do regular tune-ups on your home comfort equipment. Even premium heating and cooling systems can develop problems and lose energy efficiency over time if they are not properly maintained.

Why is my air conditioning unit freezing up?

When a central air conditioner freezes, the evaporator coil in the condenser unit freezes. This air conditioner part evaporates heat from inside to outside of your home. The following are two most common causes of evaporator coil freezing are airflow restriction and a lack of refrigerant. In either case, the final result is that the air conditioner’s evaporator coil does not adequately transfer heat and hence ‘overcools.’
