It was semi-emergency, because I'd been milking my 30 year old 3 ton York system and it was still chugging along, but it was get harder to convince the burners to fire and actually produce heat. We had other projects going, so I called our plumber. He had an opening the next day, so stock was a bit limited.

We have gas and I got a 3 ton Frigidaire 20 SEER, variable speed (Nordyne, correct?), inverter model. I know, that's a lot of SEER and I won't live long enough to reap the financial gain, but folks claim they are quieter and provide more even comfort throughout the house. Plus, he said higher SEER units have dropped significantly since last year, so it made sense to take advantage. He could have also picked up lower model, but I chose this one.

T6 WiFi thermostat

He had to run new venting about 10 feet through my outside wall. Then ran the condensation line about 15 feet the other direction into an internal drain I have that takes in from other appliances, etc. He also replaced all of the duct at the unit, as the previous duct was a tad small, though it could have worked.

I'll be at about $9,000 installed, which didn't seem bad to me. He was here with a helper for 7 hours and barely got the heating unit installed. I was here all day and it's a lot of work. I've used him before. He's pretty sharp and has always done great work. He's also going to relocate a 30k BTU wall unit I had into, what forum is this??? The garage! I might be most excited about that.

I will say this. The unit has been on for a couple hours and I can feel stronger air than we ever felt through the vents. Our duct work is a labyrinth that resulted in poor circulation, so feeling some of the further vents actually putting out air is great. I had actually gotten an estimate last year from an Oliver representative, who, as it turns out, was actually the guy who installed the system nearly 30 years ago. I didn't even mention the ducts and he said, "I remember this development. We were told make some odd runs and we just did what we were told."

Now it's off to Lowes to get a carbon detector for the garage.

I would say it sounds like a fair price for what you are getting. I would charge similar for premium SEER equipment. I typically charge $5500-$9500 for a system change out. Depending on type of equipment and how much plenum and ductwork is required. It is time consuming to do it correctly.

The variable speed units can make the conditioned area more comfortable. I doubt any equipment today will last 30 years though. I personally don't push upper end equipment, ROI isn't there. But, like in your case it can help increase comfort.

Thanks nsula country. Too funny what you're saying about not pushing upper end equipment. Half way through the day, his supplier actually called him, when he found out what unit he picked up today. He said, "Whoa! Who are you selling the Cadillac to?" Like he had a sucker on the line. Well, maybe he did (me). But he said that around here, most contractors would charge more to install a higher end system, even though many times it's the same amount of work. So the suppliers figured it was a really high dollar job.

Who knows. If I recall, the last estimate I received in 2016 was closer to $13k and I guarantee they weren't going to do everything he did. I also know those firms are typically high.

I do like this guy and when I have him here, he's always tossing in small services. Of course, I have yet to have any contractor or plumber not borrow a tool from me. Today was probably the funniest. I had a tool that none them even knew existed and he needed it. It's a drill chuck, on the end of a flex cable, and it has a pistol grip handle. Has to be 40-50 years old. Works like a champ when you need to get into a tight 45 degree angle. I'm sure plenty folks on here have something like it.

Please post a pic of this tool, quite curious to see it since I can't say I have anything like it.

Glad to hear that the higher SEER unit is improving your comfort and appreciate you taking the time to post your personal experience. I'm beginning to plan ahead for replacement of my SEER 10 heat pump in the next year or so and the tidbits of info I gather such as your experience of improved airflow are quite valuable input to me for when I make my final selection.

I'll get a picture of the drill up when I can.

He's also going to put the outside unit on angle brackets, instead of on the ground. Of course, it didn't help that the supply house gave two brackets, one with a broken weld!

Brand new HVAC and the condensate pump failed?

I had a new HVAC unit installed on Friday. Last night, the system shut down. I come to find that the Diversitech condensate pump has a safety shutoff, should the pump fail. When I touched the pump, it felt hotter than I thought it should. The Run and Alarm light were on. I drained the pump tank and the system functions fine. Pump fills and it shuts down again.

I disconnected the outlet hose and hooked another hose to it and just ran it to a bucket. The pump tank was still almost full, so I let the system run and the pump tank continue to fill. Sure enough, the Run light came on, but nothing. Shortly thereafter, the Alarm light, then the unit shut down.

Now, the system worked fine for 24 hours or so. Where the outlet line was draining into, I could see the line was full with water, so the pump was moving water at one point. I don't think the water would make it up into the ceiling and across 15' and down into the drain, unless that pump had worked at some point.

Is that height and distance too far for the pump? I don't think it would be.

Could there be a kink in the line? If so, how did the water get to the drain? And would that have burned out the motor?

I'm thinking the pump just crapped out. I told the plumber to bring two pumps with him tomorrow (I wanted a backup anyway).

Thoughts?

I bet the pump jammed. Open up the condensate pump and clean it. They usually only have two or four 1/4" self tapping screws holding the top on.

Re: Brand new HVAC and the condensate pump failed?

Thanks. Brand new? You think maybe there was some dirt from the new heater that got into the new pump? Sounds as reasonable as anything else I guess. We'll see what comes of it tomorrow.

Re: Brand new HVAC and the condensate pump failed?

sounds plausible that something is stuck in there, but regardless, better to have it looked at by the installer .
and it could have failed ...

That is neat, thanks for posting it. Makes you wonder why some of these old tools aren't made any longer given their need and usefulness in the present.

I'm so used to everyone being a DIY on here I completely forgot that it's a new install. Yeah, let the company come back...

I'd say either jammed up or failed, if jammed up I'm guessing PVC shavings from the vent pipe.

Once in a awhile **** happens, even when everything is new and should be perfect.

Haha. See, that's the problem. I do most of the stuff myself, so when a job goes sideways, no matter who does it, I get involved. I know my guy will take care of it, but I like to understand it as well, since I'm the guy taking care of it at 3AM :)

The plumber is thinking his guy kinked the hose, but I have a feeling when he looks at it today that the pump simply failed.


I remember working as a mechanic and replacing an alternator and the it not solving the issue. I spent another hour checking everything else it could be. Sent for another alternator, installed it same issue. Spent another hour. Two other techs scratching their heads. We sent for a third alternator. Bingo! So yeah, **** does happen.
