Ductless Air Conditioning

A ductless heat pump or air conditioner typically consists of a wall-mounted indoor unit combined with an outside compressor. It's most often used in a situation where a window AC unit or baseboard heating would be considered, such as a new addition to a house.

Many of the benefits our customers love about these ductless air conditioning, include:

  • Can use for cooling or heating

  • Each room has it’s own temperature controls

  • Quieter

  • More efficient

  • Take up less space; less intrusive on converting –no duct work needed

  • Good for homes with a boiler system

Duct Cleaning Service

Pollen, dander, dust mites and mold spores

What you CAN’T see, CAN Hurt you!

In today’s air-tight homes, indoor air quality is a growing concern. Most household dust contains mites, mold, mildew, pollen, and animal dander. Many of these contaminants can aggravate the symptoms of asthma and allergies. Duct Cleaning is a great way to remove dust and debris. A great time to do this is when you’re getting a new furnace, and also with the change of seasons.
