New Furnance for the House

The old furnace finally gave out. I took it apart to find out the glow-bar starter had cracked. I replaced that to find out that the furnace would keep short cycling and not come up to temperature. Probing around with the multi-meter didn’t reveal the faulty sensor. The old furnace is a 23 year old Coleman and at it’s best it was 80% efficient.

We had a HVAC contractor install a high-efficiency two-stage forced hot air furnace with a 14 SEER AC unit. The furnace is rated at 92.4% efficient. I’m still amazed that the exhaust vent is a PVC pipe. The unit is so efficient that the exhaust gases are cold.

Of course we installed the unit after the winter is over. So we’ll be anxiously waiting for winter to see what the savings will be!

On another note this is the first major project in the house where I didn’t do the work! After 12 years in the house, I finally hired a contractor to come in and do the installation. I have to say it was well worth it! They were in and out in one day. That included installing a stainless steel sleeve in the existing chimney to vent out the hot water heater exhaust. With not having the furnace vent into the chimney, the hot water heater alone does not have enough hot exhaust to make sure the acidic exhaust gases flow out the top of the chimney. The sleeve makes sure that the masonry work in the chimney does not erode.
