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.

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.

Hey, I’m Richie the owner, and if you’re wondering “how DID One Hour Heating and Air Conditioning in Charleston become the greatest heating and air conditioning company on planet Earth? Is it sheer EXCELLENCE? Is it pure HEART?” Fair questions! But the answer is really found on a dusty page of Americana, three generations ago on a Depression Era dirt farm. That’s where my grandfather Samuel Herbert “Sammy” Drew grew up.

“We needed our AC serviced. My Father had work done by One Hour, and was very pleased. I made an appointment with them; they were very professional. They text me the name and a picture of Jose H. the AC technician. Jose was professional and very knowledgeable. He explained in detail of what needed to be done to fix the problem. One Hour AC gave us a 45 day warranty, as well. I was very happy with their service.”

“Today was my first time using their services for my air conditioner, and I must say, it was a great experience. I have a membership with them, and it’s definitely been worth it.

“The technician arrived promptly as promised and proceeded to inspect the AC unit. He is very knowledgeable and cordial. He made recommendations on how to proceed but did not specify what option to choose, he left it to us. I highly recommend technician CJ for his degree of professionalism.”

“Martin was thorough, patient and kind. He told me what needed to get done and took time to explain things in a way that was clear and understandable. He took extra time to speak to my husband on the phone to explain about a gas leak he found, which was not part of the maintenance plan we have, but still very important to address. Thank you Martin!”

Deb Lawrson

“Arrived on time. He quickly understood the nature of the problem and told me what he thought could be done. He gave me a quick estimate, and I agreed to have the work done. He ordered the parts and then left to pick them up. He returned shortly and got right to work. Turns out he was exactly right about what caused our problem. He repaired everything professionally and explained what he did and why he did it. He cleaned up so well that you couldn't tell anyone had been working there. We are very satisfied and highly recommend the company.”
