Indoor Unit
Outdoor Unit

When you are looking for an inexpensive and convenient alternative to central air and heating, you will definitely want to take a closer look at the various Mitsubishi single room systems that we offer here at Bob’s Heating & Air Conditioning.

Specially designed to provide year-round comfort in a small space, the single room heating and AC systems that we offer here are an excellent option for guest houses, extensions and small homes in the Greater Seattle, WA and Tacoma Metropolitan area. They are easy to install, affordable and quite durable. If you are not sure what your options are in terms of home heating and cooling, talk to one of our expert staff members today. We will be happy to help you find just the home comfort solution you are after.

The Setup

The Mitsubishi single room split system is comprised of two separate units. The outdoor unit houses the compressor and provides coolant to the indoor unit through refrigeration tubing. This type of connection is much less invasive to install than the ductwork that traditional central HVAC systems require, and it can be installed in a much shorter time frame and for a fraction of the cost.

The indoor unit is easily mounted on the wall in the room of your choice. With an ultra-slim profile and pleasant aesthetics, the indoor units blend in nicely with the décor of your room. In fact, you will probably forget it is there in no time. The indoor unit also has its own thermostat so you can control the temperature in your room right from where you are.


Mitsubishi single room split systems are among the best on the market. They are made with only quality parts and are designed to stand up to years of wear and tear. Here at Bob’s, we only offer the products we think provide the highest quality to our customers, and these systems certainly fit the bill.

The Sound of Silence

One of the nicest things about the Mitsubishi single room systems is that it makes almost no noise at all. Most window air conditioners are quite loud, disrupting conversations and making it difficult for you to sleep. With your Mitsubishi system, however, you will not even be able to tell if it is on.

The setup of these systems with the outdoor compressor and indoor vent makes this low noise profile possible. With any type of heating or cooling system, the compressor is what generates most of the noise pollution. Central air systems place the noisy compressor outside, but these systems are expensive and invasive to install. With Mitsubishi’s single room systems, you can have the best of both worlds.

Energy Efficiency

Superior energy efficiency is another hallmark of Mitsubishi’s single room split heating and air conditioning systems. They can provide superior cooling power for just a fraction of the price of more conventional systems. And that substantial savings is stacked on top of the lower installation and maintenance costs of the single room systems.


The reputation of Mitsubishi as a leader in the manufacture of reliable and quality products precedes it in almost every discussion, and these single room systems only help to further the cause. With a system this well designed, you will find you can enjoy it for many years without worry.

And with technicians from Bob’s taking care of your system maintenance and repairs, you will be in great hands all the way around. We carry all of the replacement parts necessary to perform scheduled maintenance as well as emergency repairs, and help from Bob’s is always only a phone call away. So feel free to give us a call today. We have been serving customers in the greater Puget Sound area for more than 50 years and we would love to add you to the list of satisfied customers.
