AAD Heating & Air Conditioning is a Houston-based HVAC contractor that operates around the clock, seven days a week, making it a go-to option for residents across neighborhoods like The Heights, River Oaks, Eastwood, Afton Oaks, and Clear Lake. With a perfect 5-star rating across 41 reviews, the company has built a strong local reputation grounded in consistent, transparent service.

The company's service menu covers the full spectrum of residential HVAC needs. Air conditioning repair is a core offering — technicians diagnose and resolve issues ranging from faulty capacitors and low refrigerant to worn motors, typically restoring cooling before conditions become unpleasant. For aging or inefficient systems, AAD also handles air conditioning installation and replacement, sizing units appropriately for the home's layout and cooling demands to improve long-term efficiency.

Heating services round out the company's capabilities. Furnace installation, replacement, and maintenance are all on the table, with technicians noted for inspecting ductwork before recommending system sizes and guiding clients through efficiency options without unnecessary upsells. Seasonal tune-ups for both AC and heating systems include refrigerant checks, coil cleaning, electrical connection testing, and safety control verification — preventative work that shows up repeatedly in customer feedback as a reason clients feel confident heading into both summer and winter.

One distinguishing factor is the company's 24/7 emergency HVAC repair service. Reviews reference late-night calls answered with fast response times and clear communication — a meaningful differentiator in Houston's climate, where both summer heat and the occasional winter freeze can make HVAC failures genuinely urgent.

Technicians named in reviews — Greg, Anthony, and Tim — receive specific praise for thoroughness, patience, and not rushing through jobs. Customers highlight explanations of what caused problems and how they were fixed, which speaks to a communication style that goes beyond the transactional. For Houston homeowners looking for an HVAC contractor available at any hour and backed by consistent five-star feedback, AAD Heating & Air Conditioning is worth a call.
