Maintenance Tips and use of better systems: http://www.energystar.gov/index.cfm?c=most_efficient.me_geothermal_heat_pumps
Change air filters every time half-light is seen through____ compared to clean .
DeSuperheater, Little Water Heating "Generator of HW" seems not to perform (not much anymore): ~~ Found not having SERVICE-CLEANING VALVES FOR FLUSHING VINEGAR THROUGH EACH YEAR to clean. INSTANT WATER-HEATERS have had others dictate 3 to 5 gallons of vinegar flush (5% acetic aqueous).
Having 1600+ "Hands-On" and sold 2/3 OPEN-WELL systems (you may 90% can not 'destroy' or deplete water volumes) check for to clean iron- iron-w/ bacteria deposits from system with professionally insured advice/ or by an insured professional.
Otherwise, do not waste much money on annual nor even each 3-year (!) inspections sales set-ups with usual GeoThermal (like a refrigerator) systems...
Place a small 50-degree to 120-degree readable scale thermometer in supply ducting near furnace and check for 3-degree changes/ same conditions. Notiing this simple testing just means usually one of a very few, but important expected "normal" functions has been altered, all tests the same inputs, etc.
Older thermostats with switching positions (toggles, square tips, tec, may just need periodic moving 10-times back and forth for "cleaning".

Basic
Plenty of air, but no heating/cooling: Found needing high Return-Airs in Northern States
Hear the Air moving from blower/furnace, but none at a register: Found trunk duct too small.

~~ Found not having SERVICE-CLEANING VALVES FOR FLUSHING VINEGAR THROUGH EACH YEAR to clean.
Loop enters and leaves under a 3-DeGree differential: Found more than 1 pump on under 4-"AHRI-Rated-'TONS' " which is usually a unit with only a 3.4 C-Ton: 40k to -43,ooo BtuH compressor (LOOK AT COMPRESSOR MODEL NUMBER) inside the unit maybe set up inefficiently.
Found: Needs proper refrigerant charge ("freon needed").
Found: Operating on low speed/staging. Etc. Etc.
High Heating bills:
Aside from common "rated-TON" units having 1/2-Ton less of ari-Compressor rated pump inside unit,maybe too much back-up heat supplementing heating; UNDERSIZED- unit, ground loop under Energy-Star 32-degrees, etc.REFER TO HEAT-LOAD STUDY SHEET--- CLICK ON LOGO AT HOME PAGE AND CALCULATE OR FAX ALL DETAIL ON FORM TO 440- 285-4977
Include Degree days, City, Age of building, suspect air-tightness, Leaks in basement, Unit Model Number/ make, KHW on 2 coldest months, and be sure to include the lowest months KWH, Hot Water system (LITTLE DESUPERHEATER-GENERATOR, or is it FULL-100% On-Demand "INSTANT" Temp-Set HW ?
High Cooling Bills:
Utility charges may just be high-rates in the summer...
Please give a comparrison to "WHAT ?" that has appeared relative to judgement.
Radiant heating can be so wrongly installed to be 20% more costly (!)
Ducting -- if short-cutted, and not sealed , and low RETURN-AIRS in Northern states... can be losing 30% of operating savings estimated.
(under 5 weeks A/C--- Central High Returns or 8ft HiGH are very very helpful, extended running in the summer reduces humidity, also. )
