Apparently my trusty heat pump/ac has developed a leak (since the HVAC contractor I use had to add 4lbs of freon yesterday and had added one lb in July) in the outside unit which is a 5 ton Trane unit approx 10 years old. My inside (blower) unit was replaced about 5 years ago and is a bryant model. I am getting different opinions as to whether the outside unit should match the inside unit or if I can replace it with something different (ex. goodman). I have also been advised to be more efficient I should replace everything but since I have not won the lottery I dont see that as a viable option.
Help!!! does it really matter
