Building “Cool” Relationships!

Shandi at GSM Services

Meeting new people in the heating and air industry is always a joy for us. Recently, Shandi Maddox, our client representative, was out visiting a few companies in the area and saw GSM Services in Gastonia. She remembered seeing their service vans around town and decided to stop by!

Mark Benton, residential service team leader, recognized Shandi from talking to her before. Shandi got some great feedback from them on our products and company.

GSM Services has been around for a long time – since 1927! In fact, that’s their Twitter handle: @GSMsince1927. If you’re in the Gaston County area, check out their website and Facebook page.

We love getting connected with companies like this, because we want to help them help their customers with our products. Our products are easy-to-use, inexpensive and can save HVAC customers (both residential and commercial) a lot of money.

Let us know if you’re a contractor in the Charlotte, NC, area and would like a visit from Shandi! Or if you’d like to hear more about our products or what we do, check out our website at Wherever you are, we ship products all over the country.

Client Story! First Time Installing Pancrete

Have you ever had a product do something unexpected? That’s what happened to one of our clients! Shandi, our sales manager, talked to him last week and he told her what happened the first time he installed Pancrete. Read Shandi’s blog post to find out!

I spoke with one of our valued clients today, as he says that they are interested in our newest product, Ceramic Shield (a chiller resurfacer). They have had much success with Pancrete and V570 (a few of our drain pan resurfacers) for the past couple of years.

He is a contractor in California that does large Pancrete/ V570 applications. They like the fact that it sets up really quick and to tell his funny story, he learned this the hard way. On his very first application, he did not realize how fast the product would set up, or maybe he did not believe me. He mixed the product and began very slowly, but then the product started heating up and setting up in the containers. Since then, he has done several successful jobs using Pancrete and V570. We laughed about it, but on another note, we manufacture super easy, DIY products for “ALMOST” anyone to apply, with success.

(As you can see below, Pancrete can easily turn a rusty pan into a bright, fresh new one!)

Pancrete Job Before Pancrete Job After

Now, as we have introduced our new product, Ceramic Shield, he is interested to know how it will bring his company more business, just as Pancrete has. Maybe we’ll be able to get some before and after images of the tube sheets and end caps from the chiller that he is going to test our product on! 

Stay tuned!

Improve HVAC Maintenance in Plants & Facilities

Our friends over at Mike’s Heating & Cooling recently shared an awesome post by Plant Engineering on Five Tips to Make HVAC Maintenance More Effective. According to Plant Engineering, “Preventive maintenance is key to keeping HVAC systems running effectively and efficiently.”

We also love their advice on how to clean HVAC coils: don’t use pressure washers! 

Why? They can damage the fins on the coil, which can cause you to spend more money to repair them.

Check out their blog post and let us know what you think! :)

If you’ve ever asked a customer, “Do you want a lower energy bill and better air quality?” you know the answer to both is, “Yes!!” Customers want to save money on utility bills and they want the best, cleanest and coolest air for their businesses, homes and families.

What’s one way to give them that? Clean coils! Clean air conditioner coils have a number of benefits. Here are just a few:

  • They make your HVAC unit last longer.
  • They improve airflow and air quality.
  • They improve heat transfer.
  • They cut back on energy costs.

It sure is nice to have a little extra money in your pocket. And not only that, clean coils can prevent a unit from freezing up, a problem that could shut down your cool air for a while and cost you money in repairs. What are other downsides of dirty coils?

  • Decreased airflow
  • Lower air quality
  • Can lead to rusting, bacteria or mold growth
  • Can cause freezing of the unit

To prevent these problems, be sure to get your coils cleaned once a year or every six months. In really nasty environments with lots of dirt and grease, they might need cleaning more often. The best thing is to ask an HVAC professional, and sign up for a regular maintenance program. That way you won’t forget and your air will stay cool and clean.

Cleaning Coils Can Add Business for Contractors

For all our contractor friends, cleaning coils isn’t a tough job. We make a product that does most of the work for you. Powder Kegs are a powdered coil cleaner we make that is much cheaper than other coil cleaners on the market. Just mix it with water in a pump sprayer, spray it on your coils and then rinse off.

Keep in mind, you can add value for your customer by adding coil cleaning to your maintenance programs, if you haven’t already. It’ll keep your client happy, help them save money, and protect their coils from a potential mess. It’s just one more way for your business to grow and help your customers stay cool at the same time!
