My AC was blowing cold when he left, HAHA'S has been servicing our home for 3 years now. They have always been prompt, professional, and friendly everytime!!! Highly recommended HVAC company, FIVE STARS ⭐⭐⭐⭐⭐ Melissa Aguirre2025-05-09Trustindex verifies that the original source of the review is Google. The experience of replacing a split system HVAC was an entirely new one for me and one that I was not thrilled about. However, Faris and his crew at Haha's Heating and Cooling made it an easy process from start to finish. I received an excellent quote and everyone was super professional and informative. The work was done efficiently and very well. The stress that can come with such an event was eased by the awesome way everyone at Haha's showed up and I couldn't be more grateful. I highly recommend this company to anyone! Thank you to Faris, Damien, Kaleb, Juan and the rest of the crew for all of their hard work and getting me back up and running in short order. You guys are much appreciated! Mohammad Abuasbah2025-05-06Trustindex verifies that the original source of the review is Google. Got a new ac unit back in January, had to call them back because the ac drain hose was clogged which cause water damage. They never cleaned or checked the hose when installing the new ac unit. They charged me for something they were supposed to do in the first place. When I asked them why are you charging me they said it’s not included for them to check on it even tho we paid for a brand new unit. david schmidt2025-05-05Trustindex verifies that the original source of the review is Google.

If your system is over 12 years old and breaking down often, a high-efficiency replacement may save you money in the long run. We’ll explain both options and let you decide.
In most cases, yes. We’ll evaluate your existing system and install a smart thermostat that works with your wiring and setup. Smart thermostats like Nest, Ecobee, and Honeywell can help Olathe homeowners save money and control comfort from anywhere.
Yes! We specialize in HVAC systems for modular, mobile, and manufactured homes, especially common in Clay County. Whether you need custom ductwork or specialized equipment, we’ve got the expertise.
Absolutely. Mini-split systems are perfect for rooms that get too hot or cold—especially finished basements or enclosed patios where ductwork doesn’t reach. It’s a cost-effective, efficient fix for those tricky comfort zones.
It’s common in Olathe two-story homes for the upper floor to stay hot in summer. This can be due to duct imbalance, poor attic insulation, or an improperly sized AC. We can test your airflow and insulation to fix it without major renovations.
