Wenger, who came out the next day and offered a less costly alternative. Just the outside unit, for $2,600, so I ordered it. In the meantime, their technician discovered some wiring errors which he corrected, allowing me to have supplemental heat. He also cleaned the coil inside the air exchanger. When the technician came the next week to install the new unit, he suggested that I might want to wait 3 - 4 days and determine if the unit would function normally when the outside temperature reached 33 degrees or more. If so, then I probably did not need a new unit, and would save a lot of money! The outside temperatures had been in the single digits to below zero for several days, which is too cold for a heat pump to function without supplemental heat. After four days of warmer weather (35 degrees+) with the heat pump bringing the temperature in my house to 72, I called Wenger's back and the gentleman agreed that we could certainly use the existing unit. He didn't even suggest an extra charge or re-stocking fee. Heat pumps don't last forever, and when I replace this one I will call C.V. Wenger.

Heating Oil questions, answered by experts
Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.
DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.
An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.
Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.
Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
