Summer heat and humidity is great for sales on HVAC parts, as well as attic and bathroom fans and refrigerator parts. 

Besides  McCombs Supply seeing an uptick in sales for these parts, HVAC business across the country are busy with repairs and up keep on air conditioning units. 

McCombs has a lot of customers in the state of Texas. The Lone Star state gets very hot - it hit 106 degrees July 25 - and humidity is a killer. 

This exert of an article by Aidan Quigley for  DallasNews.com talks about what extreme heat does to your AC unit. 

On a stifling 100-degree day when the AC is on the fritz, Brandon Cronkhite knows his job lets him deliver people from a miserable fate.

So the HVAC technician from Berkeys Air Conditioning, Plumbing and Electrical is energetic as he works long hours in sweltering attics to restore cool air to those unfortunate homeowners whose systems have been pushed to their limits.

As the unrelenting summer heat descends on the D-FW region, it’s a constant battle.

“The air conditioners are in the corner of a boxing ring and the Texas summer is just beating on them," he said. 

"The longer it stays over 100 degrees the more likely there will be a breakdown, no matter how old the system is.” - Brandon Cronkhite said. 

Cronkhite is one of Southlake-based Berkeys’ 22 HVAC technicians. At this point in the year, they are working 60 to 80 hours a week, Cronkhite said, and going into attics where the heat can top 150 degrees. 

Yesterday (July 20), the hottest day of the year, an attic where a Berkey technician was working hit 156 degrees.

It's either a professional repair guy, like a Berkey tech, or it's DIYers going in the hot attic. 

Texas has extreme summer heat, but the ritual is repeated throughout the United States during the summer months. 

The Dallas News story said there are three major benchmarks where service calls spike: the first time it hits 80, the first time it hits 90 and the first time it hits 100. Again, this cycle is likely repeated in other communities in the U.S. 

Heat Exhaustion

We field many calls for Do-it-yourselfers not just in Texas, but throughout the U.S.  

Summer heat plays havoc on air conditioning units, but it is not the only item impacted by heat. Refrigerators also take a hit on hit days.  

Here are some summer/heat products that are popular items to buy this time of year. 

The website energy.gov has a story on common air conditioner problems. 

The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently.

If you allow filters and air conditioning coils to become dirty, the air conditioner will not work properly, and the compressor or fans are likely to fail prematurely. 

McCombs has condenser cleaner, including Vapco X-Factor evaporator and Condenser powder Coil Cleaner (part no. XFP-1). It sells for $7.50. There is also Nu-Calgon Nu-Brite Condenser Air Conditioner Coil Cleaner 18 oz. spray (part no. 4291-18).

Need A Motor?

  If a central air conditioner's compressor stops on a hot day, the high-pressure limit switch may have tripped; reset it by pushing the button, located in the compressor's access panel. 

If the problem persists, you made need a new condenser or evaporator fan motor. McCombs sells a lot of motors for AC units. The PC3730 is one of the many air conditioner condenser fan motors McCombs sells. 

Attic Fans

Attics need proper ventilation, especially in the summer months [See related attic ventilation story and lowering humidity in your home].  McCombs sells attic fan motors, including the popular attic fan motor ventilator for Broan 97009317 (SKU: 69317) that sells for $52.93. 

This motor also sells with a blade (AFCB3) and with a blade and thermostat (AFCB2). 

Bathroom fan ventilation motors are popular items during summer months.

The BP27 is a popular Broan bathroom vent fan motor that comes with a wheel.
