Hey there! I'm still working on updating my HVAC system! 2100 sq ft split entry in metro area of Twin Cities!! Current system Armstrong 92.5% 67k btu, 2 ton Concept 10! Both 11 years old! Both still operational but not keeping my family comfortable! Main problem is short Cycling both in summer and winter at design temps. Summer time no matter the temp outside my 2 ton cycles. I've been researching my options for over a year now and have had multiple quotes on equipment that will satisfy my family's needs and still don't know who to trust/believe. My main problem is finding a contractor to do manual J and Downsize my equipment! I am 100% sure a 40-45k 95-98% afue and 1.5 ton AC will keep us more comfortable after all the short cycling I've experienced even at -15 and 95+ out door temp. I've been looking online at equipment you all recommend and it sounds like you all like York LX series and Carriers! Any recommendations on getting contractors to down size? Thank You!
