It’s a great time of the year to clean those mini splits out. Get all that dirt, mildew, and pollen flushed out so it’s ready to go for next summer! Also, if you’re using it for heating (and you really should be) that stuff won’t bake in and be impossible to clean when it’s time because your cooling is down.

A picture is worth a thousand words, as they say.

On a Friday evening, I received a call with a referral to a new client. It’s a bustling family-owned restaurant, and I’m quite disheartened with the treatment they’ve been receiving.🫠

There’s a lot of information here, but let me highlight some key points. Within seconds, I noticed that someone had installed an oversized air conditioning system for the existing ductwork. To make matters worse, they had also overcharged the refrigerant to accommodate the oversized system. Moreover, they had neglected to maintain their customer.

The client was recently informed that there was nothing they could do; they simply needed all-new equipment. This doesn’t sit right with me, and even though my new clients will have to spend money to fix this, it definitely won’t be new equipment money.

If you are tired of hearing from your current service provider about having to buy new equipment and not getting stuff fixed so you can get on with your business, maybe try me on for size 🤷🏻‍♂️

Did you know I can connect/install your gas cooking appliances as well as fix your refrigerators?

A existing client let me pipe up a new wok range for
them last week. They’ve been an existing refrigeration client, and for some reason they didn’t know I can do gas work. I really mean it when I say if it makes things hot or cold, I can do it for you.

SOUND ON!!!

One of the things I strive to do is to teach people things about their HVAC systems that they might not know and today was a perfect example of one of those things. A long time ago I was doing a walk-through for a HVAC maintenance proposal with an old timer that I really trusted, and I complained about the fact that there was a whistling sound all over the roof because of the wind. The old timer kind of laughed at me and said well at least you know the condenser coils are clean today. I cleaned this condenser coil on a Bard HVAC unit, and I had to laugh to myself because it brought me back to that moment years ago, when I was a young green technician and lucky enough to be surrounded by people that taught me things that would be useful in the future moral of the story is.. if they ain’t whistlin’ they ain’t clean!

Heard it’s gonna be real hot this week. Saw dew points will probably be in the mid 70’s. For us on New England, that’s extreme. It’s gonna be epically humid. More than likely, your air conditioning or refrigeration system is not rated for that kind of heat. It’s outside of the design conditions we use for New England.

Give your stuff a once over. Make sure your filters are clean, look at your outdoor coils, check your drains, etc.

If you need help, please call!

I’m always straddling the fence on doing things for myself and being ready for a hell to break loose.

Even when I’m out getting a short ride in on a Monday because it’s quiet, the truck is still prepped for emergency service on your commercial refrigeration or HVAC needs. I’m ready to switch gears and help your seasonal business keep the revenue going.

I just might be a little sweaty when I get there 🤷🏻‍♂️.

Had a day today. One of my clients texted around 7:15 yesterday morning telling me their water heater blew out in their restaurant. Boy did it. Three quarter inches of water throughout the basement when I got there. Thanks to my suppliers quick response and my comfort level with dealing with landing crashing planes (also known as chaos), they are backing up and running today.
