Heaters are supposed to heat, right?

It was quite cold the day we returned from Thanksgiving break so I cut on the heater as soon as I walked through the door. An hour later we were feeling no warmth so I checked the vents. Cold air. Our nice new efficient heater wasn't heating. We had only used it a couple times prior and only for a couple hours but it had worked then. I contacted Cold Snap, the company that installed it, and one of the installers, Jon, came out the very next morning. After checking things out he determined that he had accidentally put a cap in the wrong place during the install which allowed condensation to build up instead of draining, thus clogging up the system. He spent a while up there getting it fixed. When he was done we had hot air again.

Everything was great until the next evening when the house started getting colder. I checked the vents and felt cold air. We let them know and they said Jon could come by in the morning. It was still happening the next morning but then suddenly it started blowing warm air again. When Jon arrived and did his inspection he found a hose to be the likely culprit. He said he noticed a small slit in it at the end and from what I understood, when he would touch it then it would no longer create a vacuum. So he got a new hose put in and everything seemed to be working... except that he was seeing an airflow error light show up every once in a while during the tests. We eventually found that to be caused by three of our vents being closed. Once we opened them the error went away. I also replaced the air filter for good measure.

We noticed some cold air blowing from the vents again today, but the house didn't get any colder from it. We asked and apparently that is normal. The furnace is designed to continue blowing for a few minutes after the heating stops in order to remove the heat from the unit. Makes sense. I have a heat gun that does the same thing. Now we just have to angle the vents so it doesn't blow the cold air right on top of our heads. I'd also like to say that Jon really seems like a great guy. He's been very polite and professional throughout everything. He was the one that came out after we demanded American Home Shield send someone else out for a second opinion and has been through the install, all the inspections, and now the repairs. He never made us feel like we were inconveniencing him and when he noticed he made a mistake he owned up to it and didn't try to pass it off on someone else. I respect both him and the company and wouldn't hesitate to recommend them.
