Monday, September 21st, 2020

September is when I break out one of my old chestnut topics—but it’s a perennial topic for good reasons! The same way I make sure my good readers and Russell & Abbott customers know they need to schedule an air conditioning tune-up in Knoxville, TN each spring, I want you all to know that the start of fall (this week!) is a time to size-up how your air conditioning system performed over the summer.

No, I don’t want you to open the cabinet of your AC and look at it. Leave repairs to our pros. What I want you to do is ask questions about how well the central air conditioner did its job through the hottest months of the season. This will help you with future planning. And those plans may involve getting a new AC!

Olive Explains: The Line Set for Your AC

Monday, September 7th, 2020

Time for another episode where I get to put on my professor hat and explain some of the more technical parts of air conditioning. Not too technical! I promise I won’t scare you off with frightening terms, the kind that our experts at Russell & Abbott know all about so you don’t have to! Today I’m going to be looking at a critical part of your home air conditioning system, one people often don’t think about: the line set.

The Line Set Brings Together the “Split” in a “Split System” Air Conditioner

If you have a standard central AC, you know it has indoor and outdoor parts. That’s why this type of air conditioner is called a split system. But, of course, those two parts must connect at some point: the way the AC cools down your house is by circulating refrigerant between the indoor and outdoor coils, so the refrigerant needs a way to move indoors and outdoors. That’s the job of the line set.

The line set is a pair of flexible copper pipes. One is a smaller pipe called the liquid line, and the other larger one is called the suction line. The smaller of the lines carries liquid refrigerant (you probably guessed based on the name, right?) from the condenser indoors to the evaporator. The suction line carries the hot gaseous refrigerant from the indoor evaporator back to the condenser, where it will be put under pressure and start the cycle over again.

Line Set Sizing and Placement

The line set sounds straightforward: one line to bring refrigerant into the house, another to take it out to the condenser. But I think it’s important for you to know how difficult it actually is to make sure these lines are in the right place and the right size. A mistake in sizing the line set will mean an inefficient air conditioner. Many different factors in an air conditioning system will affect the size of the line set. Also important is the line set placement and the length necessary to connect the condenser to the evaporator. If an amateur tries this job, it won’t end well!

Line Set Repair and Replacement

One common central AC repair in Knoxville, TN we often do is fix refrigerant leaks that occur in the line set. Some line sets are buried and others exposed, and exposed lines can spring leaks due to damage.

When we handle an air conditioning replacement, we’ll have to make an informed decision about whether to replace the line set as well. The new air conditioner may not be able to work with the existing line set, and we’ll always put in the right line set for the system. Disreputable amateurs often won’t do this work and leave an old line set in place. However, if it isn’t necessary to put in a new line set, we won’t force one just to charge more—we’re always honest about our services!

If you have any reason to believe your AC is leaking refrigerant, please call us right away.

Stay cool,

Olive Explains Why Indoor Air Quality Gets Bad

Monday, August 24th, 2020

air-ventWe offer services to help improve your indoor air quality in Knoxville, TN, allowing you and your family to breathe the healthiest and most comfortable air possible. If you’re wondering if this is necessary for your house, I can tell you honestly that not all homes have serious IAQ issues. But many do—and poor indoor air quality is more common today than it used to be.

Why is that? There’s a two-part explanation, and since everyone in the office is super busy working for our customers, I’m here alone to handle giving those explanations. But I live for this research stuff. Poor air quality affects pets in homes as much as it does the people! Our canine lungs don’t like dust any more than yours do.

Here are the two reasons why indoor air quality is often poor in modern homes.

Watch Out for Rusty AC Coils

Monday, July 27th, 2020

ac-coilsNobody wants anything to rust. It’s just not what you want to happen to metal! And yet, I’ve often discovered that people are willing to let “a little rust” get past them when it comes to important appliances like a central air conditioner. “After all,” they say, “What’s a little rust”?

No! I have to put my paw down on this. I’m going to tell you about the problem with rusty/corroded air conditioning coils. If you’ve found your way to my blog because you’re wondering if corroded AC coils are a problem, then you’re already ahead of the game and on your way to scheduling the air conditioning repair in Knoxville, TN to fix the problem.

Remember to Change Your AC’s Air Filter!

Hi everybody! I know you’ve probably got plenty on your mind right now, but this is the time of year when I have to bring up an important topic: changing your AC’s air filter.

I know it sounds odd to compare an air conditioning system to a pet, but this is one case where it makes sense. Pets take care of you in a special way: companionship. And you do something special for them in return: take care of their health. That means food, taking them on walks, water, taking them on walks, petting, taking them on walks, and regular trips to the vet. (Yes, I like going on walks. No, I’m not sorry to point that out!)

Your air conditioner takes care of you in a special way, and you need to take care of its “health” in return. No, put away the leash—you’re not taking your AC for a walk. You’re just going to change its air filter.

Does My Air Conditioner Also Dehumidify the House?

Monday, June 1st, 2020

flooding-roomI get plenty of questions about air conditioning systems and how they work. That’s why I have a blog! I could’ve just penned a short FAQ and then gone into retirement on my favorite couch. But I’m a hard-working blogger dog! I see great examples of hard work every day here at Russell & Abbott, and I want to do my part. I take the time to go in-depth on the questions people ask most often. And the question I’m tackling today is: “Does my AC also help dehumidify the house?”

I can answer this by dividing the question into two. “Does my AC lower humidity in my house?” The answer is yes. “Does my AC control humidity enough to make a difference to my comfort?” The answer is no.

“Professionalism” Is NOT a Brand: It’s How AC Repairs MUST Be Done!

Monday, April 20th, 2020

Lies that HVAC contractors tellThe word professional gets tossed around a lot in all types of fields. The simple meaning of professional you’ll find in most dictionaries is “following an occupation for the purposes of livelihood”, i.e. doing a job for a living.

But professional can mean many different things when you put it in action. When I say something here like, “You need to have professional repairs for your air conditioning when it breaks,” it doesn’t mean find just anybody who makes money fixing air conditioners. It’s not a “brand” either, which anybody can “sell.” No, professional means people who make a living at AC repair … ­­because they are the only ones who are qualified, trained, and certified to do the work right.

The short version: professional repairs are the only way to do AC repairs. Anything else puts your air conditioner at serious risk of bigger problems.

We Did It for Your AC in Fall—Now Let’s Grade Your Furnace in the Spring!

Monday, March 23rd, 2020

checkmark-greenLast fall I had everyone who reads my blogs on the regular (thank you for that!) do a mental exercise. Not too tough, like a Sudoku. All you had to do was give your air conditioning system a grade like in school: A to F. That helps you to plan ahead about your comfort system and take measures during the downtime period.

Now I want all of you to do the same for your furnace. Warmer weather means furnaces will soon go into hibernation—although we can never count out cold surprises during April—and attention starts to move to the AC. So it’s time to give your furnace a grade for the season it just handled, and you’ll have an idea if you need to schedule furnace service in Knoxville, TN during the spring.
