I have a 2 story home. Each floor has its own ac unit. We

I have a 2 story home. Each floor has its own ac unit. We just bought the home and don't know much about the units. The upstairs unit works well. It blows strong cold air. We got new filters and installed them into the ceiling output vents upstairs. In the downstairs, the air is not very strong and not very cool. It turns on and runs but doesn't cool very well. I found the output air vents to try to put in filters to help with efficiency, but I cant tell if they are supposed to have filters. Not sure where to start.JA: Sometimes HVAC issues that that you think will be really complicated end up being easy to fix.

A friend has an old Burnham boiler that is leaking about 1

A friend has an old Burnham boiler that is leaking about 1 drop every 5 seconds. Is this a good candidate for introducing a Hercules sealing solution to plug the leak from the inside, or should he replace the boiler? Is there danger with that chemical to mess up the zone valves or circulator?

I have a wiel McLain gas hot water boiler to heat my home.

I have a wiel McLain gas hot water boiler to heat my home. When we leave on vacation for about 2 weeks, I always shut the water off at the meter to prevent my basement from flooding in case of a broken pipe. I live in Michigan so winters are cold. I set my thermostats at 58 to 60 degrees F. When I got home about a week ago, I turned the water back on and the lines seem to need a little water. Also the boiler. WHY? I thought with a closed circuit on my boiler, it would not need any water. I cannot find any leaks whatsoever in the system. Can you explain?

I have a Coleman furnace Model G9T10014UPC13B. controller

I have a Coleman furnace Model G9T10014UPC13B. controller is a White Rodgers 50A50-241. Furnace seems to run constantly and barely keeps house comfortable although it's not that cold out. Elect bill last month was twice as high as it has ever been. checked furnace. exhaust fan comes on, burner lights, blower fan comes on, all runs well for about 1 minute then burner cuts off and I notice red light blinks 4 times, "open high limit switch". Where is this switch? What limit is it measuring, and what condition would cause it to open? The service manual talks about obstructed or crushed ducts. I checked, that's not it. Also mentions possible dirty filter. I changed filter, didn't help. Then I removed filter. still didn't help.
