Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.

How often should I service my HVAC system?

It's ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often do I need to change my HVAC filter?

Your filter should be changed every one to three months, depending on conditions in your home and your region's climate.

Do you offer purchase financing?

We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.

What are the advantages of a smart Thermostat?

Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.

HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter. In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house. Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.

What is a SEER Rating?

The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.

“I recently had my HVAC replaced by AAA Northgate, and the entire process went very smoothly. Brandon responded quickly to my request for a proposal, and was happy to provide options. Suzanna was great to work with, and very responsive to communication for scheduling and payment. Curtis & Ben were my Technicians, and they worked quickly and efficiently to get my work done in a very professional manner. Overall I was very impressed by AAA, and would definitely recommend them.”

“I initially had issues with my furnace and being 30+years decided to replace whole system. The estimate and Installation was so smooth! New furnace, new ac, and replaced the google nest with a simpler one which I prefer. We are up and running for rest of winter and for summer! I forgot the names of all 3 techs that came out to install but were very quick and great guys! also its comforting that if I have any other issues they said just to call and they will be out to help 😃”

“We recently had our HVAC replaced and we were very pleased with the whole process. They responded quickly to our call and were happy to provide us with options. We had hoped that repairs could be made but with our unit being 30+ years old we knew replacement was best. From the time they arrived to the time they left, they worked quickly and efficiently to get their work done in a professional manner. Thank you for your hard work Ben! I know if I have any questions or concerns they are the ones to call!”

“Mitchell West was our technician. He arrived when he said that would be here. He immediately diagnosed the problem with our outside AC Unit, explained the problem and needed repairs to me. He also explained and showed me how to properly clean the outside unit which would help keep the unit running efficiently. Something that I will start doing every spring going forward. He was prompt, courteous, and very informative. It was a very good experience during the service call and even better when he was done as we had ice cold air flowing again in our house. Many thanks to Mitchell and AAA Northgate.”

“This is my second dealing with AAA Northgate due to an aging AC unit. The staff is always very professional and personable, and they were quick to respond. Service calls are reasonably priced and they’re willing to work with you on financing. There’s never been any pressure or surprises when service or repairs were needed. I would highly recommend AAA for all your HVAC needs!”
