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

For optimal comfort and energy savings during summer in Greenwood, 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.

Do you provide emergency after-hours HVAC service in Greenwood?

We are available 24/7 to take your call for emergencies. Our appointment hours are listed above.

How can I improve indoor air quality in Greenwood?

To improve indoor air quality in Greenwood, 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 Greenwood?

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.

Do you offer HVAC financing in Greenwood?

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.

How often should I have my furnace serviced in Greenwood?

It’s recommended to have your furnace professionally serviced once a year, ideally in the fall before the heating season begins in Greenwood. Annual maintenance helps ensure safe operation, improves efficiency, and can extend the life of your system.

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

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

How often should I schedule AC maintenance in Greenwood?

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

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

The right HVAC system size for your home in Greenwood 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.

“The service was our mid year heat pump(s) service. Our technician was on time, courteous, and professional. He explained the need for a small part to be replaced on our oldest unit and quickly took care of it. Fortunately we signed up for annual service which provides us a discount on parts should we encounter the need. He was thorough and answered all our questions. While we have had service before, we were particularly impressed with his manners and professionalism! Great experience!”

This is my second time having them in to service my unit and I could not be happier. This company seems to really care about their customers which we all know is extremely rare these days.
