Curt Kinder commented on Christopher Morin's blog post 5 Things New Energy Efficiency HVAC Contractors Need to Know
"You left out air distribution...Without at least a passing glance at how much air moves through the system, comfort failure is a real possibility. Right-sizing via Man J is all well and good, but the system will deliver well short of rated capacity…"

5 Things New Energy Efficiency HVAC Contractors Need to Know

1. Do not sell on Price! Use 'Simple Payback'The price of High-efficient equipment will undoubtedly cost more money up front, compared to the minimum efficiency systems. Taking into account existing repair bills, utility bills, installation, and equipment costs, a high-efficient furnace, boiler, or heat pump will cost the homeowner less over the estimated 10-15 years of operation. When completing the 'Simple Payback' calculation, the high-efficient heating system in New England will win-out…See More

"I remain quite pleased with Elitesoft. No RSM, SHR defaults to 0.75, and ducts default to attic, typical in my area and certainly is responsible for approx 1 ton out of every 4."

Can you trust your Load Calc Software?

Attention Wrightsoft Users!  Have you ever completed a load calculation and it just seems like it was short of what you had expected?  Particularly when you are first starting out with a tool, contractors can make mistakes. After all, we tend to learn "the hard way", right?  In an effort to make software work, the companies tend to start with some default values that require adjustment.  For instance, most have the duct system in the conditioned space calculating zero gains or losses.  If the…See More

Do you make this mistake on Maintenance?

     Cleaning the condenser coil.  This has always been the number one task that Service Technicians avoid at all costs when maintaining residential equipment.  Maybe it is the nature of the fast paced business when the weather gets hot?  Certainly could not be the lack of water to rinse the coil as there is almost always is a water spigot on either side of the home.  I cannot figure out why,  and this may be one of the largest aspects of seasonal maintenance that impacts the efficiency of the…See More

4 Things a Quality Contractor Would Not Say

1. If you sign today, I will take $X thousand off!

This is a sales tactic often taken by a used car salesman. A Quality HVAC Contractor will price their installation with confidence, after finding a solution to fit the needs of the customer, and correctly sizing such equipment. I have no problem with "ballpark" numbers over the phone, as this can help sift through customers that are not interested in quality, so contractors do not waste time on what tends to be free…
