Importance of Proper Installation

The Department of Energy notes that improper installation is a leading factor in poor performance, increased repairs and early system failure. Undersized units run for long periods. Oversized units reach the set temperature quickly and switch off without removing humidity, leaving rooms feeling clammy. Both oversized and undersized units break down more often and can reduce efficiency by up to 30%.

M & B Heating and Air uses industry standards for each new AC installation. Several factors affect the size of the system to install including:

  • Square footage.
  • Building orientation and local climate.
  • How rooms are used.
  • Number of doors and windows.
  • Amount of insulation.
  • Landscaping and shade.

Whether you are building a new home and need a new AC installation or require an upgrade or replacement, we tailor each installation to your needs. We properly size the HVAC unit for optimal comfort.

AC Replacement

If your HVAC system is more than ten years old, is not cooling correctly or needs frequent repairs, it may time to replace it. We consider your indoor comfort needs and budget to recommend a new system. We evaluate the cooling load to ensure that equipment is sized correctly and look at existing ductwork to ensure air will circulate efficiently.

If you have added on to your home or experience uneven temperatures throughout your home, there are solutions. Ductless mini-split heat pumps and air conditioners can be used to augment a ducted system or provide conditioned air for spaces that are difficult to connect to ducts.

Energy-Efficient Air Conditioning Installation

A new installation can enhance comfort while reducing energy use. Dual- and multiple-stage heat pumps and air conditioners use less energy to operate and provide excellent humidity control. Ductless units can be turned off without affecting temperatures in other rooms. Zoned systems allow precise climate control for different parts of your home. Geothermal heat pumps use up to 70% less energy.
