Hello guys i’m new here, im 19 years old, currently working working for a residential hvac company as a maintenance/ service tech, and looking to make the jump over, i have been looking over for open entry level positions, but cant seem to find any near me area(oregon), does anyone have any tips on how to get in, or know anyone know of any company’s that’s might take me. Thanks
I starting hearing this noise inside my basement about couple days ago but didn’t realize it came from the outdoor unit until tonight. Cooling still works inside the house and the unit is keeping the temp down. Thanks.
My furnace will cycle on and the burners will stay lit for around 20-25 seconds then shut off. It will cycle back on and repeat about a minute later. Ive removed the flame sensor and cleaned it, cleaned the ground attached to the burner chassis, and the exhaust flue goes into my chimney which has a grate covering it so I dont think a bird got into it or anything. Any ideas before I throw in the towel and call a tech? I dont have a multimeter to test anything.
Also, something interesting that happens is if the furnace has been off for a bit the burners will stay lit for around 20-25 seconds. But when the furnace starts cycling back over the burners will only stay lit for 10-13 seconds.
Edit: Its fixed. Per recommendations below I removed the pressure switch tube and cleared it out as well as cleaned out the nipple that it goes into. Both were full of dirt.
I'm in a tough spot with deciding whether to replace an 11 year old furnace or repair the secondary heat exchanger. The cost to repair is $1600.00 which includes the part and labour/installation. Hoping to hear from someone who's been in the same situation and some wise HVAC techs! Thank you very much for your help.
I realize now this should have been cleaned but wondering if it was installed wrong possibly causing the secondary heat exchanger to rust out.
Hi all,
Appreciate any and all advice. To preface, I am a new homeowner and purchased a home with a 2022 HVAC system from Carrier, controlled with two ecobee thermostats. There is one unit with a multi zone system across two floors.
When I purchased the home a few weeks ago, I was able to set the air to 75 during the day and the house would easily be maintained at that temperature with the system running maybe 3 or 4 hours a day, when exterior temperatures were in the 80s - 90s.
At night, I could set the system to 68 upstairs and my primary bedroom would drop from 75 to 68 within an hour or so. Then it would run maybe another hour or two through the night to maintain 68.
Fast forward two weeks, we found a leak in our living room. Tons of remediation work requiring dehumidifiers running for 24 hours a day for a week. AC was running almost nonstop to keep the home under 85 degrees. We weren’t home for a lot of this as insurance put us in a hotel.
Once the remediation equipment was taken away, I could tell the AC just didn’t feel that cold anymore and was struggling to cool the home.
I called a local HVAC company through my home warranty, who cleaned out the system, dropped in some tablets into the condensation pump, replaced the filter (aprilaire 813) and then discovered a leak in the line set outside by the condenser.
They came back two days later to replace the line set and said to run on fan only for 3 hours and then turn air back on. Now it runs maybe 14 hours a day to maintain 75 degrees at the coldest.
Ambient temperatures have dropped to the 70s here and our air still can’t cool the home at all.
HVAC company came out again, said system was freezing over (I hadn’t used the system for 14 hours), said the filter could be causing it, reminded them it was brand new.
The air still does not feel that cold, the system has so much condensation that it’s puddling in our garage, and has to run 14+ hours a day just to maintain 75 inside.
I’m at my wits end, but feel backed into a corner that I have to use this HVAC company due to the warranty coverage. Should I just bite the bullet and hire a different company? Any other ideas that could be causing this quick death of a relatively new system? I was told the system would work better than it ever did when I paid for the line set replacement.
Has anyone ever seen this situation? I’m not sure if it’s an HVAC or plumbing issue.
Gotta love home owning. The boot under my air handler isnt even attached to the main duct. I just sealed both sides with hvac tape. But the other sides are against joist and the duct is fixed 2inches below the floor board. I attempted using half inch tubing and injecting duct mastic, but it just made a mess and didnt work. Was thinking maybe hvac company can lower it somehow but prob cant since all my electrical and water lines directly beneath it. I strongly feel they have to seal it from above by removing flooring or take out the whole air handler to get it. I think my last resorts would be to spray foam the sides and hope it dont expand inside it, or put the fiber glass up around it like how it was and just hope it slows it down, or just try seal it at the joist and hope all the hot air leaking out in that little space dosent rot the wood around it somehow.
Our old thermostat completely lost power, which its original to unit so about 19 years old. We bought new one and installed it.
Power came on for about an hour and then shut off again. HVAC guy came out and was convinced new thermostat was a dud. Husband asked him to check drain lines and transformer. Tech then said to replace entire unit.
We replaced transformer and thermostat worked great for past 3 days and now suddenly lost power again. Husband has been cleaning drain lines and hoping that fixes it and it hasn’t yet.
Any idea where else we should inspect?
After reading about the fed transition away from R410-A, what is the replacement refrigerant for my 2.5 ton Mitsubishi MXZ3C30NAHZ2 after it is no longer available?
No issues yet, just looking forward to bracing myself. Thanks.
My outdoor drain line is dripping and the pan below the first unit has water standing in it. The second unit pan is dry, so I believe I have a clog between the first and the second unit. Previously, I hooked up a shop vac to the drain line that's attached to my sink to clear it and poured bleach down the service point on the second unit, but it doesn't appear to have resolved my problem.
I believe the first unit probably needs a service port so I can pour bleach down that line as well. Should I cut out some of the PVC and add a tee before the p-trap so I can do that?
I know now this should have been cleaned. Looking for expert opinion on whether or not it was installed correctly? If not, could it be the reason for secondary heat exchanger to rust? I have to replace it and furnace is 11 years old. Thanks for your help.
I had this mini split installed a few years ago and to be honest I have been lacking on the maintenance other than cleaning the filters every few months. The unit started leaking inside and the internet pointed towards the drain being clogged. Mark this one a W in the Ai Google category as it's very clogged.
I am having a heck of a time getting it to drain. Two part question is the white PVC my drain outside, and should it be running into the ground? Most of the videos I've seen show the drain being open to the outside so you can hook a vacuum up to it for cleaning. Should I cut it to be able to access, or is it this way for a reason?
Thanks in advance for any help
Hi everyone,
I currently work full-time in HVAC in North Jersey, and I’ve been thinking about starting a small side business making custom ductwork pieces for small HVAC contractors.
The idea would be to start small, not open a big shop right away. I’m thinking about basic sheet metal pieces like transitions, reducers, elbows, caps, return, boots, patches, rectangular duct pieces, and simple custom pieces that contractors may need quickly, especially on weekends or after hours.
I’m not trying to compete with big sheet metal shops. My thought is that smaller HVAC companies sometimes need quick custom pieces and may not want to wait.
For people who have experience in HVAC, sheet metal, or running a small trade business:
Do you think this is a good idea?
Would small HVAC contractors actually use someone for this?
Is there enough demand for simple custom duct pieces, or is this harder than it looks?
What are the biggest risks or mistakes I should watch out for before spending money on tools, equipment, or renting a small space?
Would you recommend starting this as a side business, or should I avoid it?
Any honest advice would be appreciated. I’m trying to think this through before jumping in.
Thanks.
