If we do not show up within that window, your service call fee is waived. 1. Express Appointment: This is an appointment that is scheduled during a specified one-hour time slot.

You will also receive a call when the technician is en route to your home. 3. Standard Appointment: This is an appointment that is scheduled during a specified four-hour time slot. You are promised that a technician will arrive at your home within this four-hour time window. You will also receive a call when the technician is en route to your home. 4.

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.

“Exceptional AC Replacement and Professional Service! We recently had our AC unit replaced by One Hour Air Conditioning, and the entire experience was outstanding. From the initial consultation to the final installation, every team member was knowledgeable, professional, and respectful of our time and home. The installation crew arrived right on schedule and got straight to work. What really stood out to us was their attention to detail, they wore shoe covers the entire time, kept their workspace clean, and treated our home with care. The job was completed efficiently, and they took the time to walk us through the new system and answer all our questions. The new AC unit is working beautifully, and we can already feel the difference in comfort and air quality. We’re so glad we chose One Hour Air Conditioning and would highly recommend them to anyone needing HVAC service or replacement. They truly go above and beyond!”

“I had a fantastic experience with this AC contractor and highly recommend them! From the start, they impressed me by quickly coming out to provide a free estimate—faster than anyone else I contacted. Out of the three companies I got quotes from, their pricing was the most competitive without sacrificing quality. A big shoutout to Joshua, Jason, Orang, and Maryam, who worked together seamlessly. They clearly explained every step of the process—from pulling the permit to installation, and even scheduling the city inspection. When the inspector requested some additional work, they took care of it at no extra cost, and everything passed inspection smoothly. They're also a certified GE contractor, which gave me extra peace of mind. I’m really happy with the service and professionalism they provided. If you're looking for reliable, honest, and skilled HVAC professionals, this is the team to go with!”

“I had a great experience with One Hour Heating & Air Conditioning in Torrance thanks to Joshua! He was professional, knowledgeable, and extremely courteous from start to finish. He arrived right on time, quickly diagnosed the issue with our AC unit, and explained everything clearly before beginning the repair. What really stood out was how respectful he was of our home—he wore shoe covers, cleaned up after the job, and made sure everything was running perfectly before leaving. Joshua truly went above and beyond, and I wouldn’t hesitate to recommend him to anyone needing HVAC service. Great service like this is hard to come by!”

“I wanted to give Joshua, from One Hour in Torrance a review due to his amazing work ethic and great customer service. I first contacted the company in hopes of getting an AC system working in my home before the summer arrived. Joshua started by asking me various questions and soon after gave me an estimate. He was extremely knowledgeable and gave me the best price (I had contacted other AC companies nearby). He explained the process of installation thoroughly and answered all of my questions. In addition, when completing the installation he made sure that I felt comfortable with his work hours and completed the work very quickly. Thank you Joshua!”

“Josh and his team were amazing from start to finish. My AC on the roof is tough to access with multiple other companies turning down the job. Josh figured out a way to access everything and was very communicative through the whole process. If I had not been connected with him I would probably still be booking appointments for them to tell me “actually we can’t do the job”.”
