Ductless Mini-Split Heat Pumps

High Efficiency - Quiet Operation - Precise Comfort

Why do we install Mitsubishi heat pumps?

A 2004 survey by ACH&R News listed Mitsubishi Electric as the contractor's most preferred ductless manufacturer and the number one brand in price/value, availability, reliability and performance specifications. We have found Mitsubishi to be the mini-split brand with the best support in the Dayton area.

In May 2002, we became one of the first factory-certified Mitsubishi Diamond Contractors in the Cincinnati - Dayton area.

Benefits of a Mr. Slim mini split heat pump:

  • Perfect for old homes with no existing ductwork.
  • Great for garages, bonus rooms, sunrooms, and additions.
  • Best solution for hard to cool second story bedrooms.
  • Whisper quiet. With sounds levels ranging from 19-35db, you’ll barely know it's running.
  • Hyper-heat Mr. Slim heat pumps operate effectively down to -13F.
  • 20 energy star models with some rated as high as 26 SEER. Efficiency is comparable to geothermal.
  • Room-by-room temperature control. Don’t waste energy by cooling an unoccupied room.
  • Variable speed INVERTER-driven compressors adjust capacity to match demand. When the system is running at low speed, humidity and comfort are optimized, and efficiency can reach nearly 40 SEER!
  • Installation is much less invasive than a typical ducted system. Our seasoned technicians will be in and out in hours not days.

Mitsubishi Electric air conditioners are an excellent solution for cooling data centers. For a fraction of the cost of one large server room air conditioner, we can install multiple smaller Mitsubishi a/c’s providing excellent scalability and redundancy. The P-series ductless air conditioner provides enterprise-level uptime and has built-in low ambient controls and self-diagnostics. Installation in server rooms averages about $3000 per ton of cooling.

"The crew did an excellent job for the installation of our new mini-split AC. They looked into every detail during the installation and the result is super! After the installation they cleaned up very nicely and I did not have to do any further cleaning. Definitely recommend this company."

Why choose Watkins to install your new Ductless Mini-split Heat Pump?

Unlike a refrigerator, you cannot simply unbox a heat pump and plug it in. If installed incorrectly, it may only last a few years, giving you nothing but frustration. So, don't shop for a heat pump like an appliance. And remember, it's not the brand you buy but the team that installs it that matters most. Ready to learn more?
