I appreciate your helpful comment

I've seen conflicting info on whether to cut the BK jumper or not to enable Comfort-R. If mistakenly cut can you just place a jumper between R & Bk?

I'm hoping that you can help me. I have a 2300 sq. ft. home in Lomita, CA (90717) CA climate zone 6. R-11 walls R-19 ceiling. Double pane, low E windows, sliders & doors. House faces west. House is...

even for me? lol

no

I did apply for professional status but was unfortunately turned down. Maybe you could put in a good word for me. Please, please, please!

My understanding is that the total static pressure is between the furnace discharge & after the filter. The external static pressure is between the supply & return plenums. When I go online though I...

Can somebody please explain the differences between types of static pressure readings. There are so many contradictory explanations it is driving me crazy.
What is the best way to use & position the...

I have a customer with a 50 gal Bradford White r-16 water heater in it. We set the heater on just the pilot in the winter time. I was very surprised to find the when we reset the thermostat in the...

This might help. Everything you ever wanted to know about the Visionpro IAQ setup. This doesn't come with the thermostat.

The UV will breakdown certain plastics. Be careful where you place them.

If the sewer backup up how did it get high enough to enter the evaporator. It should have come up in the sink & overflowed there. The condensate should have been connected to the sink tailpiece which...

I am getting quotes on a Trane XV95, cleaneffects filter & 2.5 ton XR14. No DIY. I just want to educate myself so I know all the right questions to ask & what to look for. It seems after looking at...

Can an Honeywell IAQ cause the coils to freeze up if not set up right?

You can buy tankless heaters any where. Make sure you know what you are doing if you install it yourself. It is very easy to set up very dangerous conditions. If you have hard water, you must...

What did you discover. MAny HVAC guys have a plumbing license as well

Gas pressure is rarely the problem alone. It is more of a gas cfm issue. Tankless heaters heat the water instantly as water flows through the heater. It require large amounts of gas for short...

The main issue with tankless is that they require a minimum flow rate for the burner to remain on - usually between .5 & .75 GPM. If you are mixing hot & cold water during a shower & you have a low...

I have done quite a few tankless installations. I started working with them in 1989 when they were very uncommon here in the States. I have never installed on for heating purposes though . Most...

I am glad that you had a good experience with your Home Depot bid. It sounds like it went exactly how it should. I am sure that there are many contractors that work with Home Depot that do good work....

Unfortunately I live about 45 miles from where I work & no one wants to travel that far. That was my first thought as well. Most of my work is between Newport Beach & Laguna Niguel. I am very...

I was blown away by his suggestion of 5 tons. When I made the appt. I thought that maybe the "comfort specialist" meant actually something. I see that it is mostly a marketing ploy. I would think...

Is that UV light too close to the evaporator? I know they can cause problems with any plastic parts.

I am always taken aback when I see copper piping used for gas lines. Here in CA that is a big no-no. Install looks great though

It seems oversizing is prevalent in this industry. I am grateful that there are resources like this to educate the those interested.

I would be using this system more for humidity control than any thing else. It's not unusual to have it 80 degrees & 75% humidity. I just want to get the house comfortable when my wife & I get home....

What do you feel is the most reliable condensate alarm switch. What do you think is the best way to shut down the system if there is a condensate problem. .

In my original post I left out the square footage which is 2300 sq. ft. According to HVAC-calc the outside design temp is 80. I've looked at all the temp. graphs for my area & 80 - 85 is about right....

I recently had the Trane "Comfort Specialist" come out for a quote. They do all the work for Home Depot here in Torrance, CA. He came out, walked around the house & poked his head in the attic -...

I am doing as much research as I can before I hire a contractor to do my system. What are your thoughts on installing a filter drier on a new system?

What do you feel is the most reliable condensate alarm switch. What do you think is the best way to shut down the system if there is a condensate problem. Any pictures would be appreciated.

I noticed that the elbows were wrapped with the foil wrap. What is the best way to accomplish that? I assume that you would have to cut it into strips. The picture looks great by the way.

You sound hesitant about the wrap. What would you suggest as being best for the supply & return plenums? Thanks for your help. I am a plumbing contractor. A lot of the HVAC work I see is horrible...

The foil faced bubblewrap is made by Reflectix. It is UL rated

Is it possible to use fiberglass & wrap it with bubblewrap to acheive a higher R rating on ducts or plenums? My a/c guy can't seem to answer me.

Isn't there supposed to be a condensate trap on the coils? Just curious. Overall the system looks nice.
