Normal Service Hours, Regular Service Rates Through Labor Day

Surgi's hopes that you and your families were not harmed by the storm.  Through Labor Day weekend including Monday, we will be running normal service hours at regular service rates.

60 Months. 0% Interest on all Trane Complete Systems

If you should need to purchase equipment as a result of the storm, Surgi's is offering 60 Month financing at 0% Interest for all Trane complete system purchases.  Simply click on the 60 month link on this page for pre-approval.

We'll all get through this together.  Call Surgi's, we're here to help.  469-4232 or email us.


Surgi's will be closed during the Hurricane Isaac event.  We will be contacting you to schedule service visits when conditions allow.  As of 12:00 Tuesday, the Lake Pontchartrain Causeway was closed to trucks with ladders.  This has limited our ability to service our Northshore customers.  We expect conditions to improve on Wednesday afternoon.
We plan on running emergency service on Wednesday afternoon and regular service on Thursday.  To schedule a service call, please call Surgi's at 469-4232 or email us at
Thank you for your patience and understanding.  Stay safe.

A Case of Unforeseen Consequences

Sometimes the effort to control humidity can backfire if you don't understand the complete environment that makes up your home.  This reprint from the HVACR News explains how dehumidification features of your air conditioning system can accidentally cause the envelope of your home to collapse into major humidity problems.  The article is pretty technical but, if some of this sounds familiar, call Surgi's at 469-4232 or email us at  We're here to help.

For more information see our previous post: "Solutions to the Case of the Sweating Ducts" or HVACR News' latest article: Taking Whole-House Approach to Battle Moisture, Mold


Mold in Ductwork 1

Sometimes we do things with one goal in mind and find that we get the opposite, unintended result. Such experiences have been all too frequent in my consulting practice in a coastal environment. In the process of trying to do a better job of controlling indoor residential humidity, we actually can make the situation worse. In fact, many times things get so bad, occupants are forced to move out and expensive remediation is required.

ASHRAE recommends we keep our indoor humidity below 60 percent and our thermostat at or above 75˚F for indoor summer comfort. New high-end residential equipment is designed to make 75˚ more comfortable by offering a dehumidification option. We are much more comfortable with 55 percent relative humidity (rh) than 65 percent, given the same sensible temperature of say 75˚. Weathermen call this the “real feel” temperature. Plus, lower humidity prevents mold from spawning. So great — we can now control temperature and humidity, and most of the time the theory works.

New variable-speed equipment can operate in dehumidification mode by lowering the fan speed. This in turn slows airflow over the coil, allowing more moisture to be removed. Typically the system goes into dehumidification mode at the beginning and end of a cycle calling for cooling based on thermostat set points. For example, a rise in room temperature causes a call for cooling. If the rh is above the set point, the cooling process starts and ends with operation in dehumidification mode. The fan ramps up, slowly holding at a few hundred feet-per-minute velocity, condensing moisture out of the air very effectively. After a set period of time, the fan accelerates to full speed to deliver designed cfm cool air to the space to satisfy the latent load. Of course moisture continues to be removed during this process.

So far, so good. Once we have the sensible and latent loads satisfied, the unit cycles off. But, what if we have not reached the rh setting? This is when things get interesting.

A Glimpse Of Coming Technology - The Copeland Variable Speed Scroll Compressor

Most of today's state of the art systems use a two-stage compressor.  They operate in either high or low speed.  Although these are a dramatic improvement over single stage units that are either on or off, they rarely match the cooling output with the precise cooling requirements of the home. 

When used in residential applications the increase in efficiency could approach 27 seer.

Now, two companies - Danfoss and Copeland have released totally variable speed compressors.  Tests show that the use of these compressors could increase the efficiency of home air conditioning systems by up to 30%.  When used in residential applications the increase in efficiency could approach 27 seer.

Trane has not officially released its entry into the variable speed condenser market but we expect to see an announcement before year end.  You can see a video presentation of the Copeland compressor below.
