New Home Owner with inherited GeoThermal

Well I'm fairly certain that it's a problem light rather than a working light, since the unit next to it doesn't have it flashing, and the thermostat that controls the bad unit also has a red light that says check unit.

I'm looking around for another service company and the question is, do any of you know of good company's in the MD/DC area? Otherwise I'm just searching the net and might end up with another who could be worse.

When you get someone out there, you might consider asking them to do a thorough inspection of both systems and write you a report of all the issues they find... then a short explanation of what each issue causes and the impact of that issue. Might also ask them to rank the issues in order of importance...

My understanding from reading this thread is you will get it fixed... just want value for your $$$... which we all do.

A word of caution: Knowing what I know about these systems... it is not a good idea to DIY HVAC equipment, especially geo... too many things that are not as they appear to be... and having both the training and experience are VERY important to good results. Pay the folks to do what they are pro's at, and you will have energy bills so low, you will be amazed!!!

Keep us informed as to your progress.

People who say you should have 1 or 2 pumps based on the tonnage are wrong. That's like saying you need 1 ton per 600 square feet of living space. The size (# of tons) of your system determines the flowrate you need. The pressure drop through your system (loop + heat exchanger) then determines how many pumps you need.

I'm running a 4 ton system with a single pump in a closed loop with more than 3000' of pipe, and it does just fine. I know my flowrate is a little low, but my temps have never gone below 35 F.

Is this problem fixed? If you have 2 systems running on 1 loop,both units having seperate pumps, you need check valves installed on the out going lines of both units, otherwise the flow from one set of pumps may interfere with the flow for the other unit.
