What Are The Benefits Of Manual J Load Calculation

When buying shoes or clothes, we generally take into consideration so many things such as the design, material, and even the brand name. However, if the fit is not correct, it’d be uncomfortable to wear it irrespective of how good the quality is. The same rule is applicable when buying a new cooling & heating system for your home. Making use of an HVAC unit that is not suitable to the size of your home can cause trouble instead of giving you comfort as it is designed to do. The solution to this problem is call an expert for a Manual J load calculation to determine the HVAC system that is right for your home.

What’s Manual J Load Calculation?

Developed by the ACCA (Air Conditioning Contractor of America) Manual J load calculation is a procedure that’s employed to precisely size up the heating & cooling needed to a keep a commercial or residential building comfortable. 

What benefits your home will get from Manual J load calculation?

Different residential properties have different heating & cooling needs and it is easy to select a heating and cooling system that is ill-equipped to handle your house. Relying upon the age-old “rule of thumb” usually upshots in an HVAC unit that is either underpowered or overpowered for the said environment. Underpowered HVAC system can make your house intolerable during the summer whereas overpowered unit squanders energy while increasing overall discomfort. 

Manual J allows contractors to select the correct HVAC unit by calculating the precise heating & cooling needs of a home. A standard Manual J calculation takes most of the below listed factors into consideration:

  • Square footage
  • Building materials
  • Location & directional orientation
  • Present HVAC unit size & type
  • Heat gain & loss all through the entire home
  • Duct leakage
  • Window types
  • Insulation levels

Making use of specially designed software, contractors can suggest an HVAC unit that gives optimum comfort without employing excessive energy or wearing out untimely. Manual J load calculations are usually conducted in combination with other ACCA design protocols, including Manual S equipment selection & Manual D ductwork design. 

No HVAC unit replacement should commence without a Manual J load calculation. Get in touch with Arctic Heat Pumps today and let us handle your heating & cooling needs using our Manual J design service. We employ the industry standard Manual J Calculation software to determine the heating & cooling load. With this you can size any heating cooling equipment from any manufacture.

Heat Pumps in Nova Scotia – The Energy Efficient Heating Solution

Heat pumps are one of the significant examples that determine how far technology has come! Providing energy efficient heating using electricity is truly a tremendous technological advancement! What makes heat pumps in Nova Scotia a better choice to tackle with the cold weather is that these harvests are prevailing heat from the outdoor air and bring it inside without making use of fuels!  Limits of the Heat Pumps – Heat pumps extract heat from the air outside, hence their efficiency is directly proportional to the temperature outdoor which means when there is less heat in the air the heat pumps need to work a bit harder to extract the available heat. Top quality and highly efficient heat pumps can extract heat down to temperatures as low as -20 degrees Celsius and beyond that in some instances. Heat Pump Efficiency – Basically, two efficiency ratings are set by the heat pump industry. The first one is the Heating Season Performance Factor (HSPF) and the second one ...

How Do Arctic Series Cold Weather Heat Pumps Work?

Image
Arctic Series cold weather heat pumps are considered as one of the best heat pumps for cold climates. This factory controller system can manage two zones and unlimited zones along with the MX controller. The cold climate heat pump can be used for: ·   Space heating ·   Space heating and cooling ·   Cooling  When you set Heating and Cooling, the heat pump will control both a 3 way zone valve and circulation pump. The heat pump will use the tank temperature sensors and an air temperature sensor built into the controller to switch on and set its default to the priority zone. It can be set either buffer tank for heating or air temperature sensor for cooling until it reaches the set temperature.  For instance, if cooling is your main priority, the cold climate heat pump will cool down the room at the set temperature. After that, the 3-way valve will get diverted to buffer heating zone tank and the heat pump will then switch to heating ap...
