    Hi everyone, I've never asked for advice like this before but I'm getting a bit desperate. The apartment that I moved into a month and a half ago has two outside AC units that are right outside my bedroom window. That by itself isn't that big of an issue, noise wise. But the plumbing running...

    Hello Everyone, My 3 year old AC unit stopped working a few days ago and I noticed the lines freezing up, unit is still under warranty with Costco and scheduled a tech to come out. The guy shows up and says its going to be $200 to top up the Freon because the coil is leaking, i tell him i have...

    Hi I'm a new member. This was necessary because I discovered today that someone has cut my wire to my AC unit outside, or perhaps a mouse chewed it. I need help to know how to reconnect it. I actually feel someone cut it because the door to the on/off switch was left open and it was switch to...

    Greetings, So, In a few months. I am going to be working in New Zealand for up to the next 3 years. I have a shed that is an actual building and I am thinking of storing my homegoods there while I rent my h ome out. I will be insulating it and putting an A/C unit in the wall to control the temp...

    My father recently passed away and I'm caring for his home. He had many projects on the go. Most either unfinished or done incorrectly. I hope this forum can offer some serious advice and guidance. I'd like to begin with the air conditioner he installed, inside to outside. I don't even know...

    Short and sweet - I'm replacing my hvac system and am not sure what I should get - Single stage or two stage? I got quotes for both and the two stage is $1500 more. I figure that would have to save me about $15 a month over 10 years to be close to worth it if the only benefit I'm going to see...

    I came downstairs to a puddle on the floor and noticed this container on the side of our furnace was filled with water. It looks like the AC drain was routed through this out one point but since moved. Does anyone know what this is and why it might be filled with water?

    This is just hooking up the gauges without the compressor running. Shouldn't they be equalized? Shouldn't both of them read identical? As you can see one of them is pegged out the high pressure is pegged. I'm pretty sure my unit is running just on electric heat and not running on the compressor...

    Sometimes, usually it seems after it has not been running for a while, the AC unit makes a vibrating/buzzing noise. I've tried to pinpoint what part of the unit it may be coming from, but can't identify a source. If I turn it off with the thermostat and then start it back after a couple of...

    Hi everyone: While I'm doing research on a new furnace, I have no central A/C. For that reason, I pulled out an old air conditioner to use in my window. However, that window A/C unit is filthy inside. I don't think I ever cleaned it after about 8 to 10 years of use. A couple of years ago, a...

    Midea heat pump with P4, P6 and LED issues My 4 year old Midea heat pump stopped working. I had a HVAC tech in and the diagnosed a failed compressor. The weird thing is the LED on both inside units are discolored. The Midea service desk says they have never seen this before. Any ideas? This LED...

    Is anyone aware of a spreadsheet or online calculator to be able to compare a heat pump setup vs a conventional gas furnace + AC condenser setup? Ideally, with inputs for local utility rates, average annual hours of usage with average annual temperatures, and ratings for the heat pump and...

    Hi there folks, I just moved into an apartment where I'm facing some electrical issues that are quite frankly making me fear for my and my wife's safety. Here's the story so far: We moved into the apartment, and without plugging in any of our own devices, we were seeing the lights dim when the...

    I have a Carrier Infinity System. On this, the day temperatures reached 95, my AC stopped working. Here are the symptoms: The thermostat says "Infinity System - System Malfunction Call Technician". The condenser outside is spinning, but slowly, and only after I gave the unit a little nudge. I...

    Hi! I live in an area where it is truly difficult to find the right AC maintenance. So I tried to work around the AC and see what I could do to improve the situation myself. You won’t believe what I found! Most of the troubles with AC can be solved at home. Actually, regularmaintenance at home...

    Hello DIY Chatroom! I recently installed a NEST thermostat to my Lennex HVAC system. Related or unrelated, I noticed since i installed the thermostat, that my air conditioner (outside) has been humming more and is now making a rattle which can be heard all the way thru the lines in my basement...

    Apologies for the longer post but darn, if we're not perplexed over here. We have an older Spacepak unit in the attic and an older "Comfortmaker" compressor outside. The air conditioning unit overall has been working great up until 4 days ago. We noticed that the Spacepak was running but the...

    First off, I really hope this is some insulation and not what it kind of looks like. How much if any is it affecting the cooling when the ac is on?

    Hello, Forgive me for my layman's terms. When my a/c unit is on the air blows straight out towards nothing. I have to stand in the pathway of the air to cool down or have my thermostat on 60 to cool down the whole room. Is there an affordable fix to redirect the air towards the couch vs. the...
