What’s the best thermostat setting for summer in Greenville?

For optimal comfort and energy savings during summer in Greenville, set your thermostat to 78°F (25°C) when you're home. If you're away, raising it to 85°F can help reduce cooling costs. Using a programmable or smart thermostat can make these adjustments automatic and more efficient.

How can I improve indoor air quality in Greenville?

To improve indoor air quality in Greenville, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Greenville?

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.

We work with several lenders to provide financing options for qualifying customers. Ask your technician about your financing options.

How often should I have my air ducts cleaned in Greenville?

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Greenville, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Easley may benefit from more frequent cleanings to maintain healthy indoor air quality.

How often should I schedule AC maintenance in Greenville?

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Greenville's summer climate.

What size HVAC system is right for my home in Greenville?

The right HVAC system size for your home in Greenville depends on factors like square footage, insulation, number of windows, and local climate. A professional load calculation ensures your system is properly sized for comfort and efficiency. Oversized or undersized units can lead to higher energy bills and uneven temperatures.

E did an amazing job! He came out and got my AC back up and running! He was very polite and professional. He informed me of everything he was doing and needed to do to get me working as he was doing. I would highly recommend One Hour Heating and Air. Called about my broken AC and was back up and running in less than 2 hours!

The folks at One Hour stand behind their service. I want to give Wayne and the rest of his crew a shout-out for taking care of an issue I had with my encapsulation which was performed 13 years ago. They still stand behind their product after all this time and I don't know how many companies would do that. Thank you all so much!
