Hello fellow members ~ My first time for posting. So bear with me. My 26 year old Bryant A/C condensing unit (model#565AJ0-14) went out this summer. It is covered by home insurance (American Home Shield) and is rated at nearly 1 1/2 ton. It is part of a split system, connected to an Armstrong Air handler in the attic (model #AH24A08A … SN8493D27704) Mfg approx 1993 and rated at 2 tons.
The HVAC Lennox contractor, assigned by American Home Shield, tells me that the A/C condenser and air handler are NOT matched and has recommended that I have him install a Goodman A/C rated for 2 tons. This A/C system is cooling our upper floor (approx 630 square feet). My HVAC contractor also tells me that he can install the new AC in the next week, even though the weather is hovering around freezing at night. But he can not test the entire system until later in the spring and warns me that there might be problems with the air handler.
I really can not afford a new heat pump and feel that I don’t need it for the upper level. Possibly the lower level, yes.
I was told by another HVAC contractor that I may run into problems with the “new” Goodman unit because both it and the air handler will continue to use the outdated coolent. The Lennox HVAC dealer assures me that that he has been stock piling the older type coolant because he has many customers using the older style A/C units (R-22 vs ?).
- Did I make a good decision to go with a 2 ton replacement A/C unit?
- What problems could I have with staying with the older type of coolant system?
- If the air handler is found to be defective in the spring, what are my options at that time?
As a final comment, my attic has 4 inches of blown insulation. I plan to remove it (push it aside) and install R-30 rolls (9 1/4 inches thick) and place the blown insulation on top. Will this increased insulation cause any problems with my A/C system? I would think that it should improve it.
