When is a good time to clean coils?

Over the years our company has been asked about best practices for cleaning coils.

  • When should coils be cleaned?
  • How to tell if the coils were properly cleaned?

This is the first in a short series of blogs that addresses these issues.

A primary variable that determines ones coil needs to be cleaned is the pressure drop across the coil itself. Usually, higher pressure drops are indicative of a coil that is fouled with dirt and/or organic growth.

Dirty Cooling Coil 

Sometimes the coils appear visibly dirty, this in itself might be reason to go through a coil cleaning. Another factor is that the AC unit doesn’t cool as it should.

For example, a brand new through-the-wall AC unit, such as found in many hotels, might take 3/4 hour to drop the room temperature 8 degrees. The same unit with a dirty coil might take several hours to cool the same room. One major drawback is the unit is running several times longer to do the same work. Occupants can be dissatisfied with the slow cooling. In my own experience, I actually left my hotel room because it took several hours for the temperature to go down.

As mentioned, the unit works strenuously when it is dirty. This increased usage of power raises the electrical costs monthly. All this unnecessary work & money out of your pocket, when you have a solution as simple as cleaning the coil.

Over the past decades, we all have intuitively known that dirty coils drive energy costs up, but few know how much or if it was of any true financial consequence. Since up to 50% of a buildings electrical usage is consumed by the HVAC system, it would be good to know from actual studies how dirty coils affect your bottom line. Is it substantial or not?

Fortunately, the ASHRAE society did a complete engineering study specifically on this matter & published it in their journal.

While the results are not surprising, the affect on your bottom line is. If you do not have the article, feel free to contact us.

Drop us a line with comments, questions, suggestions, feedback on what you do with your coil. Any experiences you can comment with?

CRT’s Take On NADCA

Last week, we had the pleasure of exhibiting at the 2016 NADCA Annual Meeting, held at the Wigwam Resort in Phoenix, AZ. Many of our clients are NADCA members, so this show is something we look forward to each year.

NADCA has really stepped up their level of professionalism over the past few years! The Wigwam Resort is an extremely beautiful facility, with great food and exceptionally good service. The exhibit hall was split into 2 different rooms, which was different, but not in a bad way. I saw some of the same old vendors, and was delighted to see some new people too! 

I have been exhibiting at this show for at least 15 years, but have never sat in an any of the meetings or classes. For some reason, this year I sat through a few and actually learned quite a bit. One memorable class was, Dryer Vents: The Good, The Bad, and The Ugly. I know it sounds boring, but by the end of the class, I was freaked out about my dryer’s ventilation and lint content! Who really thinks about that?!? I’ll tell you one thing: sit through that class and YOU will think about it! Between possible carbon monoxide poisoning killing you in your sleep or lint accumulation starting a fire that can burn down your house, EVERYONE should think about that! 25719665891_cb3b5c3959_z.jpg

NADCA is gaining momentum in getting people trained and certified in duct cleaning and air handler restoration. They are truly concerned about scamming companies, who advertise $49 duct cleaning to homeowners, but then go in and quote hundreds of dollars to fix “air duct problems”, and ultimately only pretend to do the work. It was neat to see that NADCA actually worked with the tv show Inside Edition to set up a house to catch these scamming companies. Check it out here: http://ietv.co/1NvorPI

In September, we will be participating in their Fall Technical Training Conference for the first time. I am very excited about being a part of such a great organization!

What Is Condensation?

How many of us have went out of our way to shop for a glass, tumbler, or cup that will not “sweat”. There is nothing I dislike more than grabbing a cup with water droplets! These water droplets/sweat are also known as condensation.

Condensation can be in many more places than just our favorite tumbler. One major place of concern of condensation is in the HVAC System.

Condensation occurs when water vapor in the air comes into contact with something cool. Molecules slow down and get closer together & the gaseous water vapors turn back into liquid water drops (condensation). Seems kind of harmless on our cups but in an HVAC System this can cause so much damage and cost a great deal of money.

Years ago, Lynn Burkhart- President of CRT, visited a very prestigious resort in Florida. An esteemed guest had a not-so-pleasant experience in the resort.  There was a leak on the floor above, this leak damaged several expensive belongings of said guest. Can you imagine the frustration of the guest and embarrassment of the resort?


Do you know how this leak occurred? That’s right. Condensation from the HVAC’s drain pans had overflowed and leaked into the room, from the ceiling. Yikes! There is never a good reason for water to emit from the AC Unit. That is a true sign that the unit needs some TLC (Tender Loving Care). Whether it’s maintenance, repairing, or replacing. 

PM (Preventative Maintenance) is important to the health of your HVAC system. A checkup once or twice a year will help to detect & prevent an issue before it occurs. 

You can also be proactive by providing a time-released drain pan treatment PanGuard (Certified Green) or Algae Guard (EPA Registered) to keep your drain clean & free from over flows.

We’d love to hear any condensation stories you have. Please give us a call, comment, or simply shoot us an email. We look forward to chatting with you.

3 Reasons to Optimize Your HVAC Equipment

3 Reasons to Optimize Your HVAC Equipment

Homeowners have good reason to want to get the most heating and cooling out of their HVAC equipment: these systems account for up to 48 percent of a typical household’s utility bills, notes the U.S. Department of Energy (DOE). However, the benefit of properly maintaining an HVAC unit or upgrading to a high efficiency model isn’t only financial—though that’s certainly a big one. Following are the 3 top reasons to optimize your HVAC.

3. Sustainability: Another big incentive to optimize your HVAC equipment is the environment. The less electricity your home consumes, the lower your household’s carbon footprint. The government offers further cost savings in the form of tax credits to encourage homeowners to reduce energy dependency by boosting efficiency. These tax credits are a way for homeowners to save money while also feeling good about the decisions they’re making for their families and communities. 

2. Convenience: New or properly maintained HVAC equipment doesn’t just save money; it also makes a homeowner’s life easier, as unexpected breakdowns—and the uncomfortable indoor climates that accompany them—are less common.

1. Savings: The Environmental Protection Agency (EPA) asserts that an average homeowner can save as much as $750 every year by opting for an Energy Star HVAC system. However, homeowners do not need to replace their existing equipment to boost efficiency and save. Regular maintenance can help too. Below is an infographic The Refrigeration School developed that is a great source of information on DIY and professional HVAC maintenance.
