I have a commercial customer that had the same issue in her house. I found the duct in the fur down plenum (duct) had no turning vanes to direct air toward the register (1st from the air handler)....

There is nothing "wrong" with the Goodman 13 SEER units from 2003. They used Copeland scroll compressors as do most manufacturers. I had to replace a Copeland 2 stage compressor on a 19 SEER Lennox...

Please do not do this. Your questions are so basic that you cannot get it right. We do not know if you are EPA certified, have a vacuum pump, gages etc. Taking a torch to an even partially...

I wear only Red Wings. All have either a steel or fiberglass gusset in the sole to support your arch on ladders, and they last longer than any other boots that I have used.
My "carry" toolbag is a...

That is the system that I recommended today to a very good friend for a house that he has a contract on. He is very demanding, and I think that he will be happy with it. That is also the equipment...

Yes you should

Matt, there are control and safety switches in furnaces. These switches have evolved with the evolution of furnaces. If we were to give advise to you that led to your getting around these safeties,...

I installed a Lennox HSX-15 for a customer with a matching evap coil and TXV this Summer. When I finished She came out and said that there must be a problem, because she could not hear the compressor...

Waffle pads made of a rubber like material about 1/2" thich are designed for vibration dampening. I carry them in my service truck, and I get them from a wholesaler to HVAC companies. Your HVAC...

Anonymous, your next service call may very well be handed to you by the dispatcher as you drive your car to the shop with that attitude. Then as your time starts as you drive off on that call after...

I just submitted a bid for 13 ton L series and 12.5 ton T electric / gas RTUs with all the options available. The L series came in at double the T series. That said, it is comparing a Chevrolet to a...

Is the gas valve switch set to ON, if it is a start up - have you purged the air from the gas line? Did you hear the gas valve internal solenoid "click" on during the sparking?

Damn, I was just going to post something to the effect of a trane wreck, and a NEW member beat me to it.
Seriously, last week I found 2 leaking evap coils in 1 day on Tranes, and prices on all parts...

I just got a quote from my Lennox distributor for replacing MY 70% efficient, 14 year old gas furnace and the 10 SEER condensing unit that the former owner of my house had installed, matched to the...

I am going to install a dual fuel system in my home this Fall as soon as the temperature drop below 90F for a few weeks and I get a break in service calls. I have a 14 year old 70% furnace and 10...

I have changed capacitors from "close" to the correct uF (microfarad) rating on several Lennox units. They tend to be high ratings (60-80 uF) for the compressor half of the capacitor. If I were not a...

I would keep the returns that you have and add a ceiling return if necessary to give extra CFM of return air. Add a media filter or easily accessed filter base to ensure that all of the return air...

!.5 inch fiberglass wrap will not give R-6 insulation which is the minimum for 12 SEER systems required bt the International Mechanical Code and the International Energy Code. Also I would have them...

I have retrofitted 4 HSXB 15 systems this Summer, and my customers have been very happy with them. One lady came out as I was putting on the panel and said that some thing must be wrong with it. I...

I work closely with a contractor who has rigid 18v tools and he comments to his "crew" that Mike (Me) has the good stuf, referring to my DeWalt 18v 6 piece set.

Clean copper with open weave sand cloth, use even heat around the larger joints, and practice with 15% - then use 15% until your technique is second nature. At that point you can start experimenting...

It takes a lot to make a 13 year Snipe cloud up - WELL DONE.
I too checked your profile to see if you are in my area so I could offer any help.

Could be:
-fouled contactor; contactor points or weak coil
-loose connection, call for cooling from t'stat
-bad contact point in t'stat
-low pressure switch cycling condensing unit off & on...

According to Lennox service rep: recip compressors with TXVs require start kits. I had the same issue with 3 systems in a new installation on the first hot day this Summer.

You might consider a 2 stage cooling system (Lennox makes the HSX-16 series) in the 3.5 ton size. It will utelize about 65% of its cooling capacity (and corresponding electric demand) when the 2...

I would have the contractor get with the inspector, In my city the contractor pulls the permit and is responsible for the final inspection within the life span of that permit.

You said that there is a metering device. All systems have a metering device. The three most common are pistons (liquid line brazed to an adapter tube with a threaded coupling holding the piston...

Sounds like Buddy needs to call a PRO...lol

I will install a 2 stage, variable speed furnace in my home when my 14 year old furnace gives me the slightest provocation (a repair costing 20.00 or more in parts cost). I live in North Texas, and I...

I think that a service call should answer your question quickly. Last summer I found a bad condenser (outside) fan motor which would seize due to bad bearings and the overloads were bad. This caused...

I call Trane Technical Services, give my customer number and they give me technical data.

It is a 3 ton, but you will probably get more at the scrap yard for the copper and the coil stripped out than over ebay - unless of course the hot spots over the condenser fan motor is in the...

That is ugly. I like the p trap with the tail above the condensate pan, not to mention the beautiful sheet metal fit up. Was the installer's station wagon burning oil and on bald tires?

Stand by for heavy rolls

Bard seems like good equipment, and that said it seems like a pain in the a$$ to work on - possibly the houses it was installed on that are now rental units - they are essentially glorified window...

Give me a break, it's Sunday the 3rd of...

Start saving now for the new - non warranted - condensing unit that you are going to be getting off of ebay.

Check the evaporaror coil for air flow restrictions (dirty coil). Lower velocity from the restriction can cause a higher delta T, but not enough air flow to get to the furthest registers. This also...

I bought one of these sets and it works well. That being said it has a very short bottle life and a small tip. It is nice for replacing LL driers in attics and roof tops due to the small size and...

Hey Mark, I think that you are in the DFW area. I am in Fort Worth. I have a 1966 TR4A. The Red River Triumph club meets in Grapevine on the second tuesday of each month. Give me a call at...

A contactor is similar to a relay. It uses a low voltage signal (usually from the thermostat calling for cooling) to power an electro-magnet; this magnet then pulls in a heavy set of electrical...

International mechanical code, thus city code for passing inspection require "a fixed ladder to access the attic if HVAC equipment is located in the attic". Thus I will not install a furnace or fan...

3/4" od copper

What city are you in? In Fort Worth the city inspectors are pretty sharp when it comes to checking for short cuts, and the chief inspector is very free with advice to contractors about the RIGHT way...

I have a customer with 27 RTUs - 12 Rheems and 15 Lennox GCS16 units of various tonnage. I have had to replace the blower motor mounts on 5 of the Rheems due to the sheet metal that the mount is made...

I have a Promax 5140 - same company as TIF. I have had good service from it, it is oil free (very important), and not too heavy.

In Texas all licensed air conditioning (and refrigeration) contractors are required to have their Texas air conditioning contractors license (TACL) number and company name posted on both sides of...

Lennox recommends replacing line sets when changing fron R22 to R410A. That being said they train in the certifying course to be able to buy R410A systems to fill the old lineset completely with...

I recently had closed cell foam sprayed in my attic filling the 2x6 open and floored spaces over the rock wool originally installed in 1950. It not only insulated the attic, but it sealed many air...
