What our customers say

Reviews from homeowners and businesses in Lexington and nearby communities.

Our AC stopped blowing cold air in the middle of a July heatwave. They responded immediately and had a technician out to fix the unit in less than an hour. Fantastic local service.

— Sarah J., Lexington, SC

Highly professional team. They replaced our old heat pump system with a new energy-efficient model. The pricing was completely transparent and competitive.

— Marcus T., West Columbia, SC

I appreciate an HVAC company that doesn't rely on high-pressure sales tactics. Honest diagnosis, upfront costs, and excellent technical work on our furnace.

— David L., Irmo, SC

Joined their seasonal maintenance club. They just finished our pre-winter inspection and coil cleaning. Prompt, clean, and incredibly thorough.

— Amanda R., Cayce, SC

Dillon's Heating and Cooling saved us a small fortune. Another contractor told us we needed an entire system replacement, but these guys found a simple leak and repaired it quickly.

— Robert K., Chapin, SC

Unbelievable response time for an after-hours emergency call. The tech was knowledgeable, polite, and respectful of our property. Five stars all the way.

— Jessica M., Red Bank, SC

They handle all the preventative maintenance for our rental properties across the Midlands. Dependable scheduling and consistent quality.

— James P., Gilbert, SC

As a first responder, I really appreciate their 10% discount on HVAC services. They are an honest, family-owned business that actually cares about the community.

— Elena G., Columbia, SC

Clean work environment, fast installation, and they walked me through all the settings on my new smart thermostat upgrade. Excellent experience.

— Brian T., Lexington, SC

They diagnosed a major refrigerant leak that a previous technician missed entirely. Got our system running factory-fresh again without pushing a replacement.

— Megan H., West Columbia, SC

Arrived exactly on time during the holiday weekend when our air conditioning gave out. Outstanding work ethic and very reasonable pricing.

— Chris W., Irmo, SC

The technician literally shoveled out the dirt and leaves blocking our outdoor compressor baseline. It runs completely silent now. True professional care.

— Karen S., Cayce, SC

Top-notch custom HVAC layout design for our home addition project. Everything functions seamlessly and matches our existing air flow perfectly.

— Jason B., Chapin, SC

Fast local response, friendly office staff, and competitive quotes. They don't charge commissions to push unnecessary equipment upgrades.

— Taylor D., Red Bank, SC

The team was quick, efficient, and left the work area completely spotless after completing a full indoor furnace changeout.

— Ryan M., Gilbert, SC

Excellent communication from start to finish. They gave me a flat price quote over text and stuck to it. No hidden fees or surprise upcharges.

— Rachel V., Columbia, SC

They are the go-to local HVAC company for a reason. Family roots in this town show up in how honestly they treat their customers.

— Kyle L., Lexington, SC

My ductless mini-split system was failing to hold temperature. They pinpointed the issue, ordered the part, and fixed it within 24 hours.

— Stephanie N., West Columbia, SC

Very thorough seasonal tune-up. They checked the operating pressures, electrical lines, and deep-cleaned the condenser coils perfectly.

— Justin C., Irmo, SC

They kept me informed throughout the entire diagnostic procedure. Prompt emergency repair when we needed it absolute most.

— Heather P., Cayce, SC

Reliable, trustworthy, and fair. It's refreshing to deal with an HVAC company that values long-term community relationships over corporate quotas.

— Matthew B., Chapin, SC
