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 would like to share a truly wonderful experience I had with a technician who came to service our air conditioning. His name is Seth, and he made such a positive impact on us during his visit. He was not only professional but also incredibly friendly and knowledgeable. His excellent people skills really stood out, and he made us feel comfortable throughout the entire process. Thanks to the outstanding service we received from Seth, we felt assured that we were in good hands with the company, so we decided to sign up for the VIP program. We want to extend our heartfelt appreciation to Seth for his exceptional work. We hope others will recognize his efforts as well. Warm regards, The Del Rio Family Bonita, California”

“The AC unit was working perfectly. Had the drain pan replaced, now the unit doesn't work. They sent out a tech to check it out, cost free, and have solved the problem. One hour heating and air is very reliable and efficient. I recommend it for any ac and/or heating needs. Erick did an amazing job! His professionalism, dedication, and job knowledge are beyond anything I’ve seen. Thanks again to the whole team, especially to Jeff and Erick L.”

“I’m 67 years old and have owned houses since I was 19. I’ve had my share of A/C issues over the last 5 0 years. I have to say, my experience with One Hour tops the list of exceptional service. Erick was punctual, polite, knowledgeable and above all, honest and professional. It was a simple fix - corrosive wire terminals needed replace due to our proximity to the ocean. He didn’t try to upsell anything. He simply fixed it! He provided before and after pictures and we are cool again. He deserves, and is getting, a great review.”

“I want to thank Seth C from One Hour AC Service, for the service he provided to my AC sistem today. He was very professional, explained to me every detail about the steps I need to take in order to make sure my unit works properly. Thanks for your patience and your courtesy.”

“Joe was fantastic! He came out to check on our AC and not only fixed the issue, but walked me through everything in a way that actually made sense. He explained that the filter was located under the pedestal — which I had totally missed — and clarified that not all vents need filters, which was super helpful. He also tested our airflow and pointed out that we were getting less than 560 CFM when the system is designed for 1200 CFM. Thanks to his advice, I now know how to increase airflow and get better performance from the system. On top of being knowledgeable, Joe was also friendly and genuinely funny — a pleasure to have in the house. I’ll definitely be calling them again for any future HVAC issues!”
