Any HVAC experts here?

Recommended Posts

My 15-year-old outside unit recently had a pinhole-size refrigerant leak. It's been fixed, but I'm taking this as a warning that I should probably replace it soon. Before I start calling any HVAC companies to get quotes, and the associated pressure when they spring the sales pitch, I thought I'd try unofficial methods first, just to get an idea. With that stated, can anyone give me a ballpark (pun intended) figure for replacing the outside unit and any required parts for the inside of the house? It's a 2000 square foot town home (3 floors). If it helps, my current unit holds roughly 3-3.5 pounds of refrigerant. I don't need anything super fancy, just something efficient with a good reliability track record. I'd prefer to not replace my furnace, too, but if that's my best and/or only option then I guess that's the way the cards stack. Thanks!

Is this a heat/ac pump with a furnace setup in your cellar? If so, I got 17 years out of mine before getting everything replaced for $6400. We got three prices: one was $11,000 and the other $9,200. You have a little more area than me in my two story condo. There is a rating system I learned that runs 12-20 depending on your area. We got a 14 rating. You might need a 16. At any rate I would get three quotes, ask a lot of questions and take some notes.

I'm a HVAC man. Carrier is the best. cheap replacement parts and easy to work on. Remember r-22 is gone. So you may have to go to a 410A system in which the inside, outside and line sets must be replaced. Goodman is a cheap but good unit. Good luck my friend.

I would keep the A/C until it dies. It could last many more years.

HVAC contractor here.  You already spent the money to have the leak repaired and recharged; my recommendation would be to keep going with it until it needs another major repair.  The system is nearing its end life but until it needs another $500+ repair (replacing coils/ compressor) or doesn't hold a refrigerant charge for long there's no point to changing it just because its old.  When it is time for it to be replaced I recommend getting quotes from 3 companies and don't bother looking at anything more than a 16 SEER single stage system (the base 14 SEER systems are perfectly fine too).  With a few specific brand/ model exceptions the 17+ SEER systems are much more unreliable and the parts are astronomical compared to the lower efficiency systems.  If a salesperson gives you the "you and your partner need to be present at the estimate" or "you have to sign now to get the best price" song and dance throw them out of your house.

I went with a Carrier. Some people don't like it but never had trouble with the brand. Found them to be workhorse units. Good luck.

I got 25 years out of my last AC and it was a TRANE, needed the coils replaced overtop of the furnace and decided it was best just to replace everything. They pushed Carrier and so far 4 years now, its been solid and dependable.

Ive had more problems from my furnace than my AC, circuit boards, ignitors, etc.

In the long run, I pay 25.99 a month through BGE Home, and they cover all the repair costs on my AC, Heat and some hot water heater parts, and they work 6 days a week, and usually can get them out within 24 hours of breakdown.

My wife fixed our gas furnace before the service Pro was able to attend. 4 Degrees. There was some engineering background involved in her analysis, selection of tools and troubleshooting theory. She could definitely do this for a living.

The selection of tools, translation = picking the right size hammer for the job!!!! :) J/K

Good for her, saves you $$$$$$. :)

Sometimes, we over analyze things, my father taught me backyard automotive repair. 3 basic principles, you have to have fuel, air and spark to have combustion, 2 out of 3, aint going to work. :)

I image the same basic principles applies to a furnace, you have to have fuel, air and spark.

Her resolution had to do with air pressure and condensate.  And reading the red flashes on the logic card diode to do a diagnosis.

 I can tell you, if its like mine, the guy counted the red flashes, and said, oh, code XX, and pulled off the door and looked at the code cheat sheet pasted to it. :)

Sometimes the board is wrong. This is when the volt meter takes over.

I am sure it is, at least the fault gives you an indication of what might be up.

    • I get what you mean, Chris Davis seemed to hit lots of meaningless HR with no one on late in games.  But this is simply not realistic.  You get three four at bats and you do your best with them.  Maybe pitchers simply pitch differently with say a 4 run lead and no-one on base.  In fact I am sure of it... There is often some luck involved in stats and that is precisely the reason advanced metrics were created.  They are not perfect, but they are intended to make results more meaningful. If a player had a great year and hit .300 over 600 at bats that would be 180 hits. Over the course of the season, some of those at bats clearly are more important than others.  But the player isn't punished for that week he went 4 for 4 in a series against Baltimore (for example) any more than he isn't adjusted for going 0-16 against the red sox. Over the course of 600 at bats a player who hits .300 (180 hits) could raise his average to .341 if he had the identical season but added exactly one broken bat flare for a hit over each of the 25 weeks of the season.  Again, I get your point, but even Earl Weaver said, you can't run out the clock, you have to get 27 outs.  They all count.  
    • He needs to work on his transfer/release time. He takes to long to get rid of the ball after he gloves it. It's partly the hotdogging he got away with at third with a shorter throw to first. Teams have really scouted his slow release time and everyone is running all out when they hit what should be a routine grounder to short. The other day he barely threw out a catcher (McCann I think) on a routine grounder when he held the ball for an extra step. I think most things he will clear up, and he'll learn that he will have to play some hitters more shallow dispite how good he thinks his arm is
    • Looks like Willie Snead might end up being our get. That's better than BMarsh at this stage in his career, but not as nice as Dez would have been...
    • Well it will work out great if you make him co-GM with Brady.  
    • 6) Trade all your best prospects for Manny Machado. 
    • Fine.   Manny is hitting .412/.474/.471 in high leverage situations.    He’s also hitting well in medium and low leverage situations.    I’m glad he’s hot and hope he remains so.    He’s about the only player on the team who’s doing anything offensively.
