HVAC sizing is one of the most important steps in the process of procuring the right cooling and heating equipment. This is because installing a larger HVAC equipment than necessary will increase the procurement and installation cost. Furthermore, there may not be enough space for installation. On the other hand, HVAC equipment that is too small for the room may not be able to heat or cool the room effectively. In fact, it may malfunction on a regular basis. Its lifespan will also be shortened because of the frequent breakdowns. Therefore, HVAC equipment should be properly sized and installed to ensure efficient operation and an extended lifespan. HVAC Sizing Procedure To identify the heating or cooling capacity required in a building, the design, shape, orientation and size of the house, local climate, insulation levels, roof surface color, number and age of occupants, types of appliances emitting heat, thickness of the wall, window location and […]
Should I Leave Interior Doors Open Or Closed During Heating And Cooling?
Recently, researchers have found out that simply keeping a bedroom door closed can adversely affect comfort, safety and health in a house. This is because it blocks the air’s pathway, thus reducing air flow into the room and through the system as well. Pressurization of the room, which is caused by air trapped within the space, forces the cool air out of the house. All this has a significant impact on the energy efficiency of a house. How Closed Doors Affect Energy Efficiency When air is forced out of a room under pressure, an equal amount needs to be drawn so as to replace the expelled draught. Depending on the number of closed doors, the rate of entry of hot or cold outside air could go up by anything between 300% and 900%. This raises utility bills, decreases comfort and brings in a host of health problems. Since fluids seek the path of least resistance, […]
Using Fans Or Air Conditioners To Cool Your Home
Everybody wants to live in a comfortable home with the right temperature. During the summer months, temperatures can get quite high and this is the time to consider the perfect cooling system. The fans or A/C debate appears to be a no-brainer because most people prefer air conditioners.

A typical window air conditioner that runs for 12 hours per day will cost the average American $40 per month at 12 cents per kilowatt-hour. The 2.5-ton residential central air conditioner uses about 1,300 kilowatt-hours per month. This costs approximately $150 monthly. On the other hand, a […]
Temperature Control Tips And Tricks For HVAC Systems
Each season we make different demands of our HVAC systems. To keep the system running at its optimum, it’s important that we follow certain HVAC tips that maintain the system so it continues to work properly. You’ll still want to have your system serviced by a professional occasionally, but with your help his visits will be less expensive and your system will work better for longer. Start by placing your outdoor compressor unit in a shaded area. The cooler air will be easier for your unit to cool. Next, clean or replace your filters monthly. Before the cooling season, clean the fan blades and coils. After disconnecting the power, remove the fan blades and the fan grill. Brush the dirt from the blades. Once inside uncover the condenser coils and brush away any dirt that’s accumulated. Remove any dirt that has accumulated on the base pan and lastly, cover the motor other components with plastic […]
Should You Leave Interior Doors Open Or Closed During Heating And Cooling?
During extremely cold or hot seasons, your HVAC system works harder to keep the temperatures in your home comfortable. This results in higher energy bills as your system tries to cool or heat different rooms in your house. In an effort to lower these utility bills, most people apply different techniques in the hopes of reducing the amount of energy their HVAC systems use when air conditioning their homes. One such technique is closing bedroom doors when running HVAC systems. The idea here is to reduce the amount of air running in and out of these rooms, giving the HVAC unit a break from air conditioning rooms when they are not being used. This is however very far from the truth. Locking rooms to improve energy efficiency when operating HVAC systems does more damage than it does good. When doors are locked, pressure starts to build inside and then escapes from crevices in the walls […]
