DIY Heat Pump/Air Handler replacement


Then you failed to ask your wife to ask the tech how much refrigerant it would take. Or what the final price would be. And are guilty of letting yourself be taken advantage of. Be angry at yourself then. Not the tech, or HVAC industry. You had the option to say yes or no to that service call. But didn't give your wife the proper instructions to find out cost.

I have talked to many husbands over the phone when at a house to do a repair. And they always wanted to know the price. And the why fors.

In the end. IT IS YOUR responsibility to protect yourself. And make/give the final approval for any repair.

A "Professional" is someone that gets paid for what they do. Not determine if you think its an appropriate charge/fee.

Companies set fee's, not techs.

In many areas, HVAC is a 7 to 8 month make your money industry. And prices are charged accordingly.

My charge for that repair, would probably exceed what you were charged. But would also include the filter drier that should have been changed. And the proper vacuum done to the system(that isn't a 45 minute repair when done properly).

You're right jmgt it's not rocket science or brain surgery,good thing too. Brother in law had brain surgery last fall and so far the bill is over a million. If I was smart enough to be a doctor you wouldn't find me fixing rooftops when the thermometer shows 125 up there or working on heat pumps when the wind chill is 30 below zero. We,the techs in the field, are just the average Joe with training and get paid accordingly.

Yea, I see where we, typical homeowner consumers, should have done the math, based on our vast on depth knowledge of AC design, and made a better decision. Better yet, once he gave us a total, maybe we should have told him to take it back. Yea, your response is really reasonable...NOT!
For the millionth time:
Always tell the tech to give you a price before repairs.
If the price looks high call another company before you give the go ahead even if he complains about waiting.
It's common sense. Don't blame the HVAC industry, which is mostly reputable, because you come down with a case of Buyers Remorse
or find out after the fact you paid too high a price for a repair.

If a customer wants to check my price let them. like all better companies I charge higher than the hacks.

I won't change my price and the customer is either free to accept the repair or pay my service call.
One customer pulled a price for a half horse blower off the computer and and DEMANDED "The blower cost xx and you want to charge me xxxx for it?".

I just said "You are more than welcome to order that part and replace it your self. Even after you pay my service cal you will be ahead.".

I never heard a thing from her after. I won't go back if she has another problem though. i don't want to debate every time I go on a call.

DIY Heat Pump/Air Handler replacement


Had to step out for a while and now Superbowl. As for the responses, I agree with most but it still isn't right. I guess that's why we're DIY folks. Speaking of DYI, I am installing an air handler with heat strips in my workshop. Picked it up for $50. Wonder what a tech would charge me to hook this up. Probably not a job that a pro would want to do. Thank God for DIY. Sure is warm in here. 41 outside.

You need an electrician if you don't have available 220.
An hvac tech could do it, but even I would call an electrician for that.

I already have it hooked up. Fortunately my workshop has a separate 200 amp service. I do, however, have a question though. If you were to install an air handler to simply blow heat into a workshop, how would you wire the heat strips? The unit is an old GE with a 3 speed fan. The cabinet has a decal reading "with heater #...., set fan on low...". The unit had one set of strips for 8640 Watts. It also has room for 3 more sets of strips. I installed one more set. Can I still run the fan on low? It is working but will it last? Also. I couldn't find the amp rating on the contactor so I simply installed a second one. Would one contactor typically be used for two sets of strips (17,280 Watts)? The fan motor reads 2.9 amps. Also, there are no sequencers used in this unit. The strips do have the overheat fuse and the 24V for the contractors coils do go through the overheat buttons (2 separate ones, one for each contractor).

At 17KW, you better be use med speed at least. Keep your temp rise below 45 degrees.
And get ready for a jump in your electric bill.

I'm not too concerned about the electricity bill for my shop. The bill typically runs about $12 with lighting and some occasional welding and plasma cutting. Nice part is, this electricity account is separate from my house account. I am using the "low cost" electricity. I have a long way before I get into the "penalty cost" electricity. If it wasn't for the rocky ground, I would run a 220V line to power my house A/C compressor from my shop service. Maybe someday. What are your thoughts on just using one set of heat strips and leaving the fan on low? Unfortunately I didn't try it with only one set but it wouldn't take much to disconnect one. I'll just disconnect the lead to the contactor coil. In terms of heat strips, is a 8640 watt heat strip very big? Think it can warm up a non-insulated metal building workshop of 800 sq. ft., 14' ceilings when it's 35 degrees outside? Thanks for your input.

8,640(8.64KW)watts, is over 29,000 BTUs.
Might, might not heat that shop. Depends how tight it is.

How much do you use this shop. If your rate increase is at 750KWHS. Thats less then 90 hours of on time in a month(744 hours per 31 days) for the heater using only the 8.64KWs.

Next time your in the shop. And the heat comes on to maintain temp. Time it. Then multiply that by 2. And you'll know how long it will need to run with just the one heat bank. And if you'll need both banks as it gets colder out.

Thanks beenthere. The shop is fairly tight. The "R" panel metal siding and roof does have the foam strips to seal the grooves. The doors, 16' garage door and metal walk in door, seal very good. Concrete slab. I just work out there occasionally. Maybe 2 nights during the week for about 3 hours and maybe 4 hours a day on weekends. I'm building a hotrod and occasionally I tinker on something else. So, maybe 14 hours a week, 56 hours a month. Also, I'm in Texas, just north of San Antonio. Most of time I wouldn't need heat but this year, it's been very cold (and wet). Seems like whenever I have time to get something done out there, it's too cold and I just put it off. I haven't got anything accomplished since the first part of December. The heater will just be there to use when it's just too cold.

Must be that global warming thing.

Might want to use a 2 stage stat. That way, when you go out and turn the heat on. it will use all the heaters. But after its warmed up, it will only use the first bank of heat. Unless its too cold out for the first bank.

That would give you quick recovery. And then give you a more constant heat after the building was warmed up.

Just check your temp rise. If you go over 45. It tends to let the heaters get too hot, and shortens their life span.

When you say 45 degree temp rise, would I measure the temp at the air handler's intake and compare to the output air? If so, how close to the air handler should the temp be measured? I like your idea of a two stage thermostat. Shouldn't be hard to hook up since each 8640 Watt strip has it's own contactor. I wish I would have thought about that before I purchased the one I have.

Yes, at its intake, and then about 1 to 3 foot from the supply plenum. So that the temp probe you use isn't effected by radiant heat from the heating elements.

DIY Heat Pump/Air Handler replacement


Hi,
I started this thread over 5 years ago. My DIY Rheem HP installation is still performing great.

Today was the first A/C day of the season and I thought I'd do a thorough check. (I do keep the condenser coils clean, replace filters frequently and generally keep a close eye on the systems performance)

I hooked up the gauges and meters:

Ambient = 76 degrees

High side 180 PSI
Liquid line temp 82 degrees
Subcooling 12.7 degrees (Rheem says 9-12 is OK)

Low side 60 PSI
Suction Line at outdoor unit = 49 degrees
Superheat 23.9 degrees (TVX system)

Compressor amps = 11.4 amps

Delta T (air return - closest vent) = 26 degrees

Nothing seems to be much different then it was 5 years ago
