Services Overview

Here’s a closer look at what One Hour Heating & Air Conditioning covers in each category:

One Hour Heating & Air Conditioning offers comprehensive AC services, including system repairs for refrigerant leaks, compressor failures, and airflow issues. If your unit is outdated or beyond repair, the company provides professional AC installation and replacement services for energy-efficient models. Routine HVAC maintenance is also available, including coil cleaning, filter replacement, and system inspections to improve efficiency and longevity.

Whether you have a furnace, boiler, or heat pump, One Hour Heating & Air Conditioning provides heating system repairs for ignition issues, pilot light malfunctions, and uneven heating problems. If you need a new system, the company handles heating installations, including high-efficiency furnaces and heat pumps that help lower energy bills. Seasonal maintenance services, such as filter changes and system tune-ups, ensure reliable heating throughout the colder months.

Proper ductwork is essential for efficient heating and cooling. One Hour Heating & Air Conditioning offers duct cleaning services to remove dust, allergens, and debris that can impact air quality and system performance. If your ductwork has leaks or damage, technicians can seal or repair it to improve airflow and efficiency. For new homes or system upgrades, One Hour Heating & Air Conditioning also provides professional duct installation services.

Indoor air pollution can contribute to allergies and respiratory issues. One Hour Heating & Air Conditioning offers various solutions, including advanced air filtration systems, purifiers, and UV light sanitizers that help remove airborne contaminants. The company also installs humidifiers and dehumidifiers to regulate indoor moisture levels, preventing mold growth and improving overall comfort. Additionally, heat and energy recovery ventilators help maintain fresh air circulation while preserving heating and cooling efficiency.

A properly functioning thermostat is essential for maintaining home comfort and energy efficiency. One Hour Heating & Air Conditioning provides thermostat repair services to address connectivity issues, calibration problems, and power failures. If you’re looking to upgrade your entire cooling and heating system, the company offers thermostat replacement services, including smart thermostats that allow remote access and programmable settings for improved energy savings.

Emergency Services

One Hour Heating & Air Conditioning offers emergency services 24/7 with no extra fees for nights, weekends, or holidays. Whether your heating stops working in the middle of winter or your AC breaks down on a hot summer day, its HVAC contractors are available to restore comfort to your home quickly.

Guarantees

One Hour Heating & Air Conditioning provides two key service guarantees:

  • Satisfaction guarantee: The company promises high-quality workmanship and customer satisfaction. If you’re not happy with the service, the company will make it right.
  • On-time guarantee: If a technician arrives even one minute late, you won’t be charged for the service.

One Hour Heating & Air Conditioning Cost

One Hour Heating & Air Conditioning provides an upfront pricing guarantee on repairs, replacements, and AC tune-ups, which means the company tells you exactly what a job will cost before it starts working. We gave the company a call to find out exactly how its pricing system works. A representative told us it doesn’t have set pricing for services—costs are determined based on the specific needs of a home. This means that instead of providing you with a basic estimate, it’ll customize pricing to your unique situation.

The company did let us know that it charges a diagnostic fee. This is essentially a trip fee—whether a technician shows up to do a repair or not, you’ll need to pay this fee for an inspection.

One Hour Heating & Air Conditioning offers each of the following payment options:

  • Credit card: The company accepts major credit cards, including Visa, MasterCard, Discover, and American Express.
  • Financing: The company offers financing through Synchrony Bank with deferred interest plans.

One Hour Heating & Air Conditioning Reviews

One Hour Heating & Air Conditioning is accredited with the Better Business Bureau (BBB) and has an A+ rating from the organization. Because some third-party review sites have separate pages for the company’s different locations, we collectively looked at reviews from customers in Durham, North Carolina. However, we recommend homeowners look up reviews in their specific location, as local management may impact your quality of service.

Here’s two examples of customer reviews for One Hour Heating & Air Conditioning:

“The whole process from start to finish was efficient, friendly, and professional. [My technician] took his time to explain everything he was checking and repairing.” —Monique W. via the BBB

“The maintenance technicians were always okay but once you have repairs, they push you to replace [the system].” —Jessica K. via the BBB

We also received the following note from one of our readers, named Jack R., in June 2021:

“I called [One Hour Heating & Air Conditioning] last July for repairs to my AC. They finished the job and while paying for the repair I asked them how much is their one year preventive maintenance. They said $168 and includes two visits. I said OK and cut them a check for that day’s repair and annual preventive maintenance. They are counting that July visit as a FIRST visit of the preventive maintenance visit. They paid another visit in November 2020. Our dispute is that they should NOT count the repair visit in July 2020 as the first preventive maintenance visit. I filed a complaint [and the company] accepted their mistake and agreed to refund me $84. Unfortunately, so far no check.”


Our Conclusion

One Hour Heating & Air Conditioning is an HVAC provider that provides service in 39 U.S states with generous guarantees and 24/7 availability. We recommend the company if you have an issue with your air conditioner or heating system and need fast, guaranteed service.
