Today I visited with Kelly in her Okotoks home because she is getting quotes to install a new central air condition system and furnace. Upon inspection of the 1268 square foot home built in 1994 I found the furnace is original and past its life expectancy. I performed a heat load calculation and determined the home requires 51780 btus to properly heat, and a 2 ton ac system to properly cool. Kelly and I discussed the use of the newer refrigerant and Kelly would prefer to install a unit using the older r410-a refrigerant. The water heater is 10 years old and kettling (popcorn popping noise) when it’s fired up indicating heavy sediment build up. There is poly b piping throughout the home with no pipe protection system and no water softener.
