So I am looking into buying an AC unit for my Grandma and am trying to figure out roughly how much this will cost before I bring out someone for an estimate. She lives in Socal and removed the unit the house had when she moved in 25 years ago, according to her the coil is still there and drained of the refrigerant. I suspect after 25 years that stuff will not be reusable, but hopefully the install won't be to hard since the infrastructure is still there. The house is 1750sqft 3bdrm two story. I am hoping to spend less than $4000 (probably split with other family members) and am wondering if any knows roughly how much this stuff costs. Also I am considering using the Costco/Lennox deal, with various promos it will be zero interest and ~14% cash back.

For a new house with forced air heating is almost $10,000 a sane price for a new install 4 ton AC unit in any state? (but more importantly, in California).

kastein posted:Depends, what brand? My Midea 3 ton split unit was $2500 in parts and shipping, but expect probably another few hundred to a thousand in materials and installation (since you already have central air) and the rest is gonna be their labor rate plus whatever brand and size difference costs. Lennox EL16XC1-048 (mid range, 16 seer, single speed). skipdogg posted:That sounds about right for a replacement of an existing AC unit. I was quoted similar at my old house. So my house does have forced air heating (gas furnace), but is not "plumbed"/ac ready. This means they'll need to run the power to the condenser and the coolant lines to the coil. Vents should be good, air handler I don't know.

ExplodingSims posted:Yeah, Lennox is going to be more expensive, but if they need to run power, lineset, etc for the new condenser and evap, than $10000 is pretty reasonable for a new install. After running all the numbers more carefully it now stands: $7,000 Carrier 3 ton SEER 14, $7,400 Airtemp 4 ton SEER 14, $8,900 Airtemp 4 ton SEER 16, $8,000 Lennox 4 ton SEER 16. I've asked for a 4 ton Carrier quote for apples to apples.

tangy yet delightful posted:So wildfires...I've got some home depot level 10 rated filters (which is like MERV 13 from what I can tell) being shipped to me that should arrive Thursday. Outside air quality will still probably be between 300-400 when they arrive. I in a new energy efficient home such that luckily the smoke infiltration isn't too bad but I still want to clean it up asap. You can probably figure this out based on the size of your house, compressor, furnace, and most importantly air handler and return. The answer is actually pretty fast to cycle all the air in your house (think about how quickly your heater or ac change the temperature). I am in the same situation, new house in CA and have been using the AC with a Merv 13 filter to improve the air quality, I run it about six hours a day. Also new homes in California are required to have vent sealing testing, but not blower door testing.

My new AC system seems to have a 6.5/8.5 minute duty cycle, is this normal? When it cools off outside the on time stretches a few minutes more. I'd prefer it cool longer and stay off longer, I read the thermostat manual and can't find any settings that seem to control that. New house, new single stage ac, Lennox m30i thermostat.

Explosionface posted:The two settings that jumped out at me as possibly affecting this are the Feels Like setting, since they note they control off of that (and outside temp affects it) and the Fan Circulate time. I would try the Feels Like setting first since I suspect it will have more of an effect than anything else. Dunno if anyone else has any better ideas. Thanks, I think "Feels Like" requires the outside temperature sensor, which I don't have. I will try upping the fan circulate time.

My thermostat has started power cycling at the end of the heat stage. It just kinda turns off, or at least resets when it hits the set temperature and the relays click. I've never been downstairs to watch it so I can't tell exactly how the process starts. It's a 2.5 year old Lennox M30 attached to a Lennox AC and almost as new furnace. It's two weeks for the HVAC company that installed it (and the AC) to come out to check on it. Is there anything to be especially worried about or super easy to fix / check? Assume decent home repair skills and equipment, and new construction. Also, what's the current recommendation for aftermarket thermostats. I hate the M30, it constantly cycles on and off trying to maintain temperature with no way to make it overshoot. I'm looking for something more controllable, doesn't need to be smart or internet connected, and it's just controlling single stage / zone ac and forced air heat.

PageMaster posted:Please bear with me for the potentially long post! I'm going through some treatment at home which gives me a lot of time to troubleshoot and maybe gather too much info: My nest thermostat has started giving me an Error, (no power to RH wire) shortly after we turn the heat on, and I'm trying to figure out what's normal operation, and what's a problem. Naturally our home warranty company hired the worst rated contractor in the county to come look at it in a couple weeks so I'm just thinking about it while we wait. Here's the standard cycle that happens on the natural gas furnace when we turn the heater on: This is extremely similar to the problem I had with my furnace recently (described a few pages ago). For me the solution was the furnace tech adjusting the gas pressure in the furnace. The tech also mentioned airflow as a potential issue, but decided it was unlikely for my specific system. Did filter/airflow changes end up fixing this for you?
