For potential new home owners, one of the first things you take into consideration is the plumbing, cabinets, floor and counter tops. The HVAC system ends up being the most unsatisfying feature of the new home.
There are 9 important things you should remember when you get your HVAC system installed. These will help avoid having your AC company come back out to your home.
- Make sure the design and ductwork are correct. If they aren’t balanced or sized correctly your home may not cool or heat properly. Externally insulated ducts that are round are the most efficient type of ductwork.
- Be sure the size of your HVAC unit is correct. The size of your HVAC system depends on the size of your home as well as how many windows , how much shade and how much insulation your home has. How much air leaks in and out of your home is also taken into consideration.
- Placement of your outdoor unit. The worst place to put the unit outside is by a bedroom window, which could be bothersome to you and your family. Also, make sure it is somewhere where it can’t be easily damaged.
- Balance dampers in ductwork. The worst place to adjust the air coming into the room is at the diffuser grill. Balance dampers should be installed away from the diffusers and should also be balanced by a qualified tech.
- Refrigerant. Federal Law states that R-22 should be cut out by 2015. I recommend systems that use the eco friendly R-140A.
- Location of the Air Filter. They should be located where they can be easily accessed. Filters should be changed every couple of months so it should be located easily.
- Return Air. Air that enters a room must be equal to the amount of air that leaves the room. Otherwise there is no space for the cool air to occupy. Each room should have a register and return air diffuser.
- Condenser Coil. Single metal coils last longer and are more efficient, for example aluminum or copper coils. This is very important for corrosive environments.
- Efficiency. The minimum efficiency for air conditioning systems is 13-SEER, this has been in effect since 2006. The higher the SEER, the lower the energy use.
