What to Expect from an Air Conditioner Consultation

Air Conditioner Install in Vancouver

Summers are getting hotter in Metro Vancouver which may be a good thing for some people. But for those of us who are used to moderate temperatures, we may want to install an air conditioner in our homes to help us sleep at night or relax indoors during the evenings. There are a number of things that a professional contractor will need to know before selling and installing an air conditioning unit in your home.

An in-home consultation will have the air conditioning contractor first evaluates your house and performs a heat loss calculation. This calculation will reveal what size air conditioning unit you will need. We recommend that whoever you use does perform this calculation to make sure they are putting in the correct size unit for your home and are not recommending a unit based on their experience and site unseen.

Factors Affecting Air Conditioner Size

  • – Amount of wall and attic insulation your home has
  • – Where your windows and doors are
  • – Types of windows and doors you have
  • – Orientation of your home to the sun.

This heat-loss calculation can show you possible benefits of upgrading the insulation in your house to make your home more energy efficient. By making your home more energy efficient, you may be able to reduce the size of the air conditioner you need.

Properly Sized Air Conditioning Unit

An undersize unit won’t be able to cool rooms down completely on the very hot days and will cost more to operate because it has to run longer than a correctly sized one to try to keep the rooms cool. An air conditioner that is bigger than what you need also costs more to operate because it simply takes more electricity to run a bigger unit. An oversize unit doesn’t lower humidity effectively because it cools the air so quickly that it shuts off before it has a chance to circulate the proper volume of air past the coils to extract the necessary moisture. The result is that your room doesn’t seem as cool as the thermostat reads. The room may feel clammy and damp.

Air Conditioner Efficiency

After determining the correct size of the AC unit for your home, our air conditioning contractor will cover efficiency, which is expressed by the seasonal energy-efficiency rating (SEER). SEER rates how many Btu an air conditioner will remove for each watt of electricity it consumes. The higher the SEER, the less it costs to operate. Units with lower operating costs, tend to be higher quality, have more safety features, better sound shields and lower voltage requirements. The higher the SEER, the higher the initial cost for the unit.

Types of Air Conditioning Units

Next step is to decide on what type of system to buy. There are two kinds. A “package system” gangs the condenser, which cools the refrigerant and exhausts warm air, with the fan-and-coil system, which cools and blows the air. The ducting connects directly to the unit. This is essentially a large wall air conditioner with ducts.  The second option is a “split system,” where the condenser is outside the house and the fan-and-coil system are inside. The two parts are connected to each other by pipes that carry refrigerant. There are other items and pricing that will be covered during your air conditioning consultation and the contractor will leave you with a written copy of the quotation with the price of what the entire job will include. We do offer financing for those who want to pay over the course of months instead of at one time.
