Many homeowners in the Northwest are getting central air conditioning for the increasingly long months of warmth. One of the biggest service complaints we address in the summer is from people who find their AC isn’t cooling the house to a low enough temperature for their liking. Washington Energy Services goes on air conditioning service calls daily and has these tips to share from our experience:
First, we will assume that the AC unit is actually able to run. If it is not running at all, you will need a service call by a trained air conditioning technician. If it's just underwhelming you with its cooling, you may have one of the following conditions:
1. The Air Conditioner has not been recently serviced. Maintenance is recommended to ensure the unit is working properly and to manufacturer specifications. This is especially important in areas like Seattle where the AC is not used until July-Sept and then sits idle for 9 months. Leaves and debris can get into the unit in the off season too.
2. The air handler or furnace that sends the cool air through your house via the ducts may not be working properly. There could be dirty air filters as well as dirty coils.
3 The duct work may leak and need sealing and insulating---especially if the cold air return is in the attic. Duct leakage in older homes without duct sealing can go from 10%- 40% of total air lost in transit.
4. The unit was set up to meet municipal code (the law) and it’s not sufficient to produce the cooling level they desire because it is set to that standard. How can that be, you ask?
If AC’s are sized correctly to the Washington State Energy Code for cooling, that would be 78 degrees inside at 83 degrees outside for Seattle. If the temperature outside is warmer than 83, the home may not get cooler than 78. In this case, the best we can do is make sure the AC system is charged correctly, the filters are clean, the temperature across the coil is a 20 degree drop, and duct leaks are sealed. A home owner doesn't want to hear this, but it is the law. Heat Pumps are typically sized for heating as the primary function and do not have this issue when they cool.
If you are in this boat or you suspect you are just losing the cool because of a drafty house, the solution is to tighten up the seal of your home. That may involve air sealing, duct sealing, insulation and weather stripping among other solutions. The best way to determine what should be done is to have a Home Energy Audit by a BPI certified contractor.
