Can someone recommend a good HVAC tech in the Southern California (San Diego, near Torrey Pines) area? A friend of mine is looking for someone to give her a second opinion.
Thanks!

Great! Thanks for that info, cmajerus. Makes me feel better...

If you have read any of my other posts, contractor installed xv80 80K...

I asked because my HVAC guys just ran a load calc on my home, and the design temps on their calculations were 22/92. Cheers!

How do I find the most accurate design temperatures for my area (Atlanta,GA), for both winter and summer? Are these temps "rule of thumb" or are there specific numbers that are most often used?...

Yep, I see those RISE numbers in the service facts. I mentioned this to my contractor and he said they are satisfied with my current numbers (gas pressure and temp rise), because they called Trane...

Second-
Just curious, why shouldn't ComfortR run with 350 cfm per ton???

Thanks!

Second,
Dip Switches 7 and 8 are currently ON/ON (Heat-Low Airflow). The changes were made a few days ago. Also note that the First and Second Stage Temp Rise were taken in this mode (Low heat...

C-
Gas pressure is 1.5 (Low) and 3.0 (High), with Temp Rise = 44 in Second Stage. First Stage Rise was 40/41. Are those NORMAL Gas Pressures?? Jeff

The furnace (xv80) was just installed two weeks ago..

I have an older outside AC unit (Trane XE 1000 2.5 ton), so I assume it is only a 1-stager. Does the TCONT802 get me anything extra in cooling mode, or is the Comfort R settings on the board...

I would call your friendly neighborhood HVAC professional and ask them to come out and install. (forum is non-DIY).

You get a nice new stat, with a nice warranty!

Just a follow-up: I left the Trane regional tech guy a voice-mail in the evening and asked him to call me. He called me back first thing the following morning. He was a very sharp guy and a pleasure...

I was able to finally track down the regional distribution center and actually talked to someone and then got the name/number of one of their HVAC techs, who was OUT on a service call! Tigerdunes,...

Yes, Sir! I have a Trane .. nice. I'll try and contact them. I just called the 1.877.my.trane number and talked to an older (80+) lady in Kentucky. Really nice, just thought it was funny, b/c that...

Are there any forum members that service areas outside Atlanta (west)? If so, please let me know or send me contact info. Thanks!

If an HVAC systems' ducting is inadequate and supply air is greater than return air, can too much pressure build inside of a "tight envelope" home?
note: Please let me know if this post should be...

Thanks Geodude, I'll look into those. Cheers!

I actually just removed 4 of the 6 return grilles and noticed a very small difference (reduction) in air noise. Hopefully will have my tech give me system static, true temp rises and gas pressure in...

I'll have the tech back out to measure the first and second stage temp rise, check gas pressures and total system static pressure. Question: What are potential problems that could arise with my new...

What impacts the temperature rise? Is it the longer the thing runs, the warmer the exchanger gets? .. Or gas flow, or too little air?? The tech measured at 40 when he was out a couple of days ago...

I just had a new gas furnace installed and the idea behind my "oversizing" was about the same: I was told --> That the 80K, 4-ton unit was recommended (for me)to handle the cooling needs (Georgia)....

My Outdoor Unit is a Trane XE1000 (14.5 years old). I'm actually getting ready to have the HVAC guys come out to run the load calc numbers, and recommend an upgrade. Any suggestions: XR14, XL14, 15...

Thanks Second Opinion!

I'm also about to have a 2-stage stat installed, as I just had a Trane VS 2-stage furnace installed. I understand the role the stat plays while heating, but does it contribute as much during the...
