hey-hmmm. ok-they did replace our thermostat with a trane one that goes with the unit -will try and find out. it has a humidity setting, temp setting.

They probably shook loose a lot of dust in the plenum and ductwork when they installed the new system. It may take a few weeks to disperse. Keep checking your filter.

Hey-good point-the filter- we used a 3m filter for years-I wonder though if its right for this system? It seems the inside temp on my thermometer is about 2 degrees higher than the unit thermostat consistently-does it need to be recalbratied?

There's sometimes a "temperature offset" setting in thermostats that you could use. I don't believe its possible to "recalibrate" the temperature sensor on electronic thermostats.

Most people in the know will say to avoid the 3M Filtrete filters - too much resistance to airflow. Just use cheap fiberglass filters and change them frequently.

So seems its solved- texted w the repair man-he said to add 4 to the calibrate setting on thermostat-which I did. and its much cooler now. I knew it was off bc my thermometers showed inside temp 81 all day and night. when I calibrated-now matches the thermostat setting of 77. whew

Hey
So Im a bit confused. So this is very new trane hvac- and the new thermostat is trane xl824. I noticed it was 81 in the house, but the temp on the tstat was 77. the tstat was set at 77. So the repair guy said to calibrate it- to add 4 degrees (as it was 81 in the house and tstat set for 77).

So-the calibration was on -1. I raised it to 3. But man it was colder than I thought! Set tstat at 77, the temp would get to 75-76. So I took down one degree from calibration from 3 to 2. That will make it a bit warmer right? Idk why I find this calibration confusing.

Airflow issues are among the most common HVAC problems.

If you suspect you have HVAC airflow problems, you’re probably experiencing one or more of the following symptoms:

Hot and cold spots throughout your space. This is often one of the first signs of HVAC airflow issues.

Pressure imbalance. Do you have doors slamming by themselves, strange whistling noises and drafty areas? These are symptoms of air pressure problems caused by poor airflow from HVAC systems.

No air coming out, weak air or low airflow from vents in your house or commercial space.The problem could be throughout the space, or you could have one AC vent not blowing air in one room. This is when you begin to realize something is wrong.

Your AC system blows warm air. Now you KNOW something is wrong!

If you ignore the problem for too long, the strain on your system can lead to COMPRESSOR FAILURE. The compressor is like the heart of your air conditioner, and when it goes, there’s a good chance you’ll need a new unit.

Ah, the spammer is back (^^^^^^^).

The solution may be purchasing the right air filter. This article might be able to help:
