free yes there are. 1.the larger 005 var speed air handler to improve the system's eff numbers. 2.new and correctly sized refrigerant lineset. 3.Edge Carrier thermidistat 4.staged heat strip. either outside condenser would be fine. the two stg Comfort 16 series would be preferred over the sgl stg 15 model. get the final mdl numbers both outside and inside units and post before signing any paperwork. IMO Good Luck!

Good product and good warranty. Brand is sometimes overplayed a bit. While we all will have our preferences on brand for whatever reason, they are all pretty similar as far as parts go. Some tend to be more reliable, and some have better performance figures. What particular models, if you know off hand? I would go with a heat pump that has a model number starting with "A"--this is a genuine Amana product. The thing that seals the deal is the better installation, not the more popular brand.

Unit is a Trane 5 ton heat pump, air handler TWE065E13FBO with BAYHTR1419 strip(s) factory installed (per label on the unit itself). Long story short I am concerned that the Trane dealer that originally installed it should have either run a second feed from the breaker panel or should have upsized the 8-3 nm. Easy to see that this is the original wiring from when the home was built based on the wall texture/paint overspray on the wiring at the top of the main panel. 8/2 coming off a 60A breaker feeding the outside unit (XL1800 weathertron) and 8/3 feeding both breakers/disconnects (2 60A Square D breakers) in the air handler from a 100A breaker in the main panel. Assuming that the heat strip(s) are wired in a way where #8 is adequate(if wired in at all) its still over protected at the main panel and in my opinion needs to be addressed. Not mentioned when the home inspection was done and not mentioned when a Trane dealer tech from a company other than the original dealer replaced the tstat a few years ago due to the back lighting failing on the original. Old thermostat had emergency heat option not sure this one does (Trane Tcon something which I believe is a Honeywell with Trane name on it). If a second feed was added is there a requirement that the breakers be tied together in the main panel? Trane documentation just says should be wired in accordance with NEC and state/local regulations. J

Not a complete model number for air handler. You want the TAM7 060 size for best matching AHRI number. 5768010 Active Systems TRANE XL18I TRANE 4TWX8048A1 *AM7B0C60H51 1585 1270 48000 13.00 17.00 47000 9.50 30800 1 HRCU-A-CB 359 1006 Yes Location please. Too many details missing as to comment on price such as model of thermostat, size of heat strip, new lineset or flush old. I do not recommend Clean Effects, prefer the Perfect Fit media filter cabinet. No maintenance or cleaning required. IMO
