merv 16 furnace filter question

merv 16 furnace filter question

Posted On: July 7, 2023
I have been dealing with dust allergies in a house I moved into recently and was recommended to get a Lennox Healthy Climate 16x25x5 filter for my HVAC system by a relative. He isn't a technician though, so I was hoping to get input here. My system is 1.5 years old and I don't want to damage it with air restriction. But I also don't want to be miserable with dust allergies 24/7. I've seen mixed reviews on if the Lennox Healthy Climate does restrict or if it has enough pleats that it doesn't effect airflow. Could anyone weigh in on this so I can...[More]

why do new homes being built have mini splits not vented ac

why do new homes being built have mini splits not vented ac

Posted On: July 6, 2023
A lot of newly built homes in my area appear to have mini splits (you can see them on the side of the house). Also, a friend of mine is a very successful real estate agent that sells fancy homes in a fancy market (500k+ homes) & all the newly built homes have mini splits, no vents. I am surprised by this. My friend just says they are easier to have than vents — sure i get that. But if someone is having a 800k house built, the homeowners probably arent looking to cut corners to save $5k. They want something that is most reliable & efficient....[More]

help with ac wiring

Posted On: July 2, 2023
Quick synopsis: I just purchased a house built in the 1830's it's been through several owners and just before we bought it had A/C added but not a new thermostat wired in. The old thermostat had no cooling option, I'm having an issue wiring the new thermostat. There are three wires, a red wire I have going to “R” a white wire going to “W” and a Blue wire going to “Y. The fuse in the air handler(?) is not blown and power is turned on at the inside breaker, outside breaker and switch on the side of the furnace. Question from user IDONTL...[More]

Posted On: June 30, 2023
Hi all, found a technician with good reviews but said he's been on biz for 2 years. Live in new build, 18 months old and ac on main floor isn't blowing cold air anymore. HVAC guy is still here after almost 4hrs and doesn't seem to know what the issue is yet. Has found some other issues like intake vent is burnt out and permanently closed, too much low voltage going to hvac panel outlet. Should it take this long? He's charging by the hour and has been on the phone for half of it w a friend in the biz trying to trouble shoot. Ac on top floor whic...[More]

Ok so it's been a HOT Sunday in my household. We realized as I left to run errands that it was 5° warmer than it should have been. By the time I got home to check it out, it reached 83° inside. Went through basic troubleshooting and easily found a power line issue… turned out the 60A breaker on the main feed for outside had a bad leg. Went and tracked down a replacement and success! We now have 240v at the outside unit! . After a little while, it hit 85° and I realized it's still not right. Nothing is making any strange noises, and everyth...[More]

what could cause 1 yr old hvac to create smoke smell

what could cause 1 yr old hvac to create smoke smell

Posted On: June 25, 2023
The unit still actively and quickly cools the house, but it was burning something causing Carbon monoxide and nauseousness. This was confirmed by the emergency utility technician that came out to rule out a gas leak and help identify the problem. Could opening more registers or removing the register filters help solve this issue? The builders used the floor registers as a trash can for sweeping away debris, so I had put filters to try to keep the air cleaner for my family. We also closed some registers (as directed on the main unit's instructio...[More]

What do HVAC techs actually do when they perform annual maintenance in AC/furnace? My house is 3 years old. Do I need to have HVAC serviced? I don't currently have any issues. I have a very tight budget right now, so I want to know how much I can expect to spend and why. Question from user OppositeArt8562 at hvacadvice at reddit. Answer: Well if you're broke don't worry about it. Maintenance whether it's AC or furnace is to just get out there, test components, clean stuff up that sort of thing. The biggest thing it to try to find issues so they...[More]

If you notice your pool heater steaming, it could indicate a potential issue that needs attention.

I noticed my outside unit wasn't running, i left it completely off for 30 minutes and tried again, still nothing. Then I reset the breaker and turned it back on at the thermostat again, instantly working and turned back on and it's currently cooling. So the AC unit is only working after the breaker inside my house is reset. Sorry if this is confusing, I have very minimal knowledge on this and I'm a little flustered.
