answers from the hvac pros
Frequently Asked HVAC Questions
Get quick, plain-English answers to the AC, heating, and air quality issues homeowners ask most, along with guidance on when to call a pro.
Why is my AC not cooling effectively?
Several issues can cause this, from low refrigerant levels to a dirty filter or a malfunctioning compressor. Our certified technicians can quickly diagnose the root cause and provide an efficient solution to restore your home’s comfort.
What should I do if my furnace is making a banging noise?
A banging noise can indicate a variety of problems, such as an ignition issue or problems with your ductwork. It’s best to turn the system off and call a professional. Our licensed technicians can safely identify the problem and perform the necessary repairs.
How often should I service my heat pump?
We recommend servicing your heat pump at least once a year. Regular professional maintenance ensures it operates at peak efficiency for both heating and cooling, prevents unexpected breakdowns, and extends the lifespan of the unit.
What are the pros and cons of a ductless mini-split system?
Ductless systems offer highly efficient, zoned heating and cooling and are great for homes without existing ductwork. Our experts can walk you through all the benefits, such as improved energy efficiency and flexible installation, and discuss any considerations for your specific home.
How can I understand the 25C tax credit for HVAC?
The 25C tax credit offers homeowners significant savings on qualifying high-efficiency HVAC equipment. We can help you select eligible systems, from heat pumps to furnaces, and provide the necessary documentation to ensure you can maximize your savings on energy-efficient upgrades.
