Help with AC
I have 10+ year old Payne systems. A 3.5 ton for upstairs & a 5 ton for downstairs. The main problem is that the 5 ton unit is rated for 29.1 amps on the name plate. And it was installed on a 30 amp breaker! So .. this thing pops the breaker unless I keep the outside unit very clean. I think the units are rated about 10 or 11 SEER.
If I hose down the unit, the current draw goes down. So I've ordered a misting kit as a short term fix.
Some background. We live in the Houston area, Lake Conroe actually. The house is a 2 story box. Upstair sq ft about same as downstairs. Front entrance opens to 2 floor. Square footage is about 4600 sq ft. Heating is all electric.
The upstairs 3.5 ton definitely runs longer than the downstairs unit.
Since my house is a 2 story box, why are the units not the same size?
I'm looking at replacing the units, (preferable not all at once) with either Heat pumps or geothermal heatpumps.
With the 30% tax credit with a geothermal unit, that looks enticing. But I haven't seen any pricing yet.
For a air source heat pump, I'm looking at 16 SEER I think. What would the current draw be for say a 3.5 & 5 ton 16 SEER unit?
I haven't got unit numbers or details yet. I did get one quote for 16 SEER Goodman units. Are the any bad names to stay away from? Preferred brands?
Any help/guidance would be greatly appreciated.
