I recently bought a home and througout the summer noticed that the air conditioning was running continuously and the house wouldn't really cool down below 80 degrees, even at night. We normally keep the thermostat programmed to 78 day/82 night. Our electric bill is almost twice that of our neighbors who have about 50% more house than we do.
We called a HVAC service company and they told us that there isn't really a problem, that the heat pumps in our area are only designed to cool 15 degrees from the outside temp, and with a 95-100 degree day, 80 is all we can expect. They told us to hold off another month and they would do a fall "check-up" of the system, which we did.
We had them come out to service the system today for the regular maintenance inspection/service, and the guy told us that we have a mismatched system, ie, two different manufacturers.
Outdoor unit is a 2 ton Arco Aire HP5024A2C1. Indoor unit is a Janitrol model A30-10. the home is 25 years old, outdoor unit has questionable age, indoor unit is 5-7 years old.
I've already been told both of these are cheap builder units and one or both need to be replaced. I was also told that with a 1600 sqr ft house I should have a 2.5 ton unit outside.
I would like to know if these two units are truly incompatable, or if I need to call a different service tech to come fix it.
The tech also stated "superheat is operating at 0 deg indicating liquid presence in vapor line. Possible overcharge or mismatched capacities."
So, in addition to all this, we call the home warranty company and they said they could not cover it because the mismatched system is not their fault.
So, now I have two months in a row paying 300 each for the electric bill vice 150, I just paid 76 for a tech to tell me he couldn't do anything but offer a replacement system, and the home warranty company says they can't cover it.
So, any suggestions?
I know I'm going to hear dump the Janitrol (Junkitrol, whatever) and buy a Trane or other high quality unit, but I just can't afford that. Same goes for you get what you pay for. The economics of the situation says I'll do what I can with what I have and fork out the least amount of money in the process.
Is there anything I can do to get the system I have working?
If I have to replace one or the other, I'd like to replace the outdoor unit and buy a compatable 2.5 ton unit. Would the Goodman CPLJ30-1 Heat Pump work for this application?
A sincere thanks in advance for any input that is offered.
