✅ Why Choose Haha’s for HVAC in Olathe?

Alex “TheRealMalman” Mallen
Local KC Customer
I tired to be Mr. Repairman and fix my own AC in the last week of July. I failed. I made a call to Haha's and within a hour had Faris onsite at my house. Faris didnt force things I didnt need and listened to what I wanted to do and made great suggestions for different solutions. I went with a new unit for AC and Furnace with humidifier and a new hot water tank. The sales call was on a Friday. On Monday, the install crew worked all day and was not able to get the hot water tank installed in the same day. Things happen and they said they would be back the next day to install the water tank. They did everything they said they were going to do. They go the wrong size of filter the first day, I was replaced when they came back. They didnt forget a single thing they said they were going to do on the first day to the second. It was great service. I would highly recommend this business to anybody in my family and look to continue to work with HAHA with all of my maintenance for my new unit.

Frequently Asked Questions

Do You Have Any Questions?

Need Help for system replacement consultation? No worries its Free

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.

If your system is over 12–15 years old, constantly needs repairs, or isn’t keeping up with Olathe’s temperature swings, it may be time to consider a high-efficiency replacement. We offer honest diagnostics and free second opinions to help you decide what’s best for your home and budget.

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.
