I had a new Goodman gas furnace and ac installed a few months ago. Everything is running fine but I have a question about the ECM blower. I believe it's a 9 speed constant torque ECM . I've never has a system with one of these. Only PSC motors. The speed for the heat and ac are set to the...

I am helping a friend replace my gas furnace and AC here in Maryland. He has his own HVAC company but does mostly commercial work. He does do residential but he doesn't go looking for it. I did the gas pipes and he made two comments. He mentioned code and also BGE (our gas and electric...

Hello, 120 volt wiring on a new Goodman gas furnace install. If you're installing a metal box with a switch and outlet on the outside of the unit can the furnace wires be pulled into the box and connected. I've seen people still make the connection in the furnace junction box. Seems odd but...

Hello, I have an older Bryant (Carrier) 90+ gas furnace? I've noticed lately the exhaust has a smell. It smells like when you first start up a vehicle. I don't smell it inside and my CO monitor hasn't indicated anything. So should the exhaust smell and if it shouldn't what can I look for? Thanks.

Hi all, Sorry for the long post. Thanks for reading and any help. I'm looking for some educational help with a possible piston orifice issue. I have a Nordyne 18K split system installed in 2012 that is cooling the upstairs of my cape cod. Air handler is a B6BMM024K-A. Condenser is a...

Hello, I have an 11 year old Nordyne JS4BD-018KA condenser. The scroll compressor runs backwards several times a day. Usually later in the day when it's hot but I'm not sure that has anything to do with it. I know it's running backwards because it's noisy and the air coming out of the top is...

Hello, My friend just had a new heat pump installed and he said it's not any better than his old system. When I looked at the picture it looks like the air coming out of the air handler would not flow smoothly and would create pressure. It's like that at the floor as well. Any thoughts would be...

Saw this vise going to the scrap yard. Anybody know anything about it. Just curious. The guy only said that it was given to him years ago. It was mounted to a heavy steel stand.

I'm looking for some jack stands to support my 06 Tundra. I have some shorter stands but need to go taller. I was looking at the Esco 10498 for $125/set. https://www.amazon.com/dp/B0019JVIPM/?tag=atomicindus08-20 I see that HF has their version of the Esco for $100/set...

I built a porch roof about 32 years ago when I was young, had lots of energy and wood was cheap. I noticed one of the outer 6X6 posts has some rot. The other two are fine. The decay is about 1/4" deep. I guess that's not too bad for the time it's been there. I went down a little further and...
