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.

“Our furnace wasn't heating the house at all. Even though we're not far from nicer weather, it still was an artic feeling temperature in the house of 58°. Not having a relationship established with a company for major home services makes emergency type situations extremely stressful and a little scary to be honest! I picked a couple different companies that did service in our area and looked at customer reviews and sent a message to 3. Northern One Hour Heating and Air Conditioning was the first to respond. The person I then received a call from was impressive with the attention given to how I was feeling matching what I was saying and responded accordingly. Erin was the technician to come and was here in in less than 2 hours. She was professional, knowledgeable, and wonderful to deal with. She was thorough and took the extra time to explain everything and answered all of my questions. Erin found the issue and had everything up and running in no time. Even with it being a pretty basic fix, she didn't cut corners and gave attention to detail which overall left me feeling comfortable and confident in my choice to use Northern One Hour. I would absolutely recommend them to anyone and will continue to use them moving forward. I'm relieved to know I now have my "go to" for everything HVAC! You're awesome Erin and thank you again for everything!!”

“Chad Plumley visited on a Sunday and provided an estimate for a replacement furnace and ac due to our existing equipment having a heat exchanger that had failed. Chad is one of the best HVAC salespersons because he just stated the facts and gave me the impression that he was providing the best system for us and the best price available. Also, just a nice dude! Update…Jim, Alex and Gordon all worked on our furnace and water heater replacement. The guys took great care at protecting the existing flooring in our home, removed all the existing equipment safely and installed, tested and confirmed operation of the new systems. 10 out of 10!!”

“I love One Hour Heating! I had my furnace replaced by them a year ago and now I have their membership. They called me yesterday about my annual tune up for my furnace and were able to schedule an appointment for today. They are always on time and their technicians are wonderful! Troy was kind, helpful and gave me some great advice to keep my furnace and humidifier running efficiently and safely! I highly recommend. ⭐️⭐️⭐️⭐️⭐️”

“I had an excellent experience with Ben Franklin Plumbing. From start to finish, their communication was outstanding—they explained everything clearly and let us know what to expect at every step. Brendan, our technician, was highly professional, skilled, and punctual, arriving right on time and completing the work efficiently. He also took the time to explain what to do if any issues arise in the future, which I really appreciated. Additionally, Brendan was very respectful of our home, ensuring everything was left clean and tidy after he finished. I wouldn’t hesitate to recommend Ben Franklin Plumbing and Brendan to anyone looking for reliable and high-quality plumbing services! Blaine MN”
