HVAC Maintenance Tip: Keep Equipment Clear

By Will Housh, HVAC.com When it comes to HVAC maintenance, how you maintain the areas surrounding your equipment can be just as important as the maintenance of the actual systems. Poor maintenance in the immediate areas surrounding your air conditioner or furnace could decrease system efficiency, damage components, and even put your family in danger. Follow these HVAC maintenance tips to protect your heating and cooling equipment. Keep the exterior condenser unit or heat pump clear of items. You should leave a clearance of at least two feet surrounding the unit. This will facilitate proper airflow, and allow access to the unit should repairs be required. Never install an enclosure directly against the unit. Outdoor items should never be stored surrounding the unit. Local building codes require gas furnaces and other gas appliances maintain a clearance from the floor and surrounding walls. Space should be left for many reasons: allow… Continue reading

Why Has the Cost of R-22 Increased?

R22 Freon

If “R-22” just sounds vaguely like a smallish robot from Star Wars, don’t worry—you’re in the vast majority. The U.S. government-enforced restrictions—and the ultimate phase out—of R-22 Freon probably isn’t on your radar, but it has been on ours for years. The impact for you, the consumer, has been—and will continue to be—felt when you get the bill for an air-conditioning system recharge. A once small fee has skyrocketed as production of R-22 continues to drop. In fact, only 13 million pounds will be produced in 2017, followed by 9 million pounds next year and 4 million pounds in 2019. Finally, beginning in 2020, only reclaimed or recycled R-22 refrigerant will be available to service existing systems. But, why? What’s the deal? The deal is that the government hopes to replace R-22 with a safer material—one that goes easier on the ozone layer. That’s an initiative we can all get… Continue reading

Air Conditioning in Northwest Arkansas

Life in Northwest Arkansas was very different before air conditioning. In fact, without air conditioning, we wouldn’t have all those “Best Town in America” awards we’ve received. Before air conditioning, towns like Fayetteville, Springdale, and Rogers had no chance of competing successfully for national businesses. Just like the airports, roads, and educational institutions that made prosperity possible for Northwest Arkansas, air conditioning was a necessity for getting a seat at the national and international table. Early residents of Northwest Arkansas relied on design features to keep their homes relatively cool. Dogtrot houses, high ceilings, and sleeping porches helped families make it through the summer by taking advantage of the breezes. Factories? There were canneries in Northwest Arkansas in the early 20th century, but actual industrialization was just not practical. The heat inside a factory in an Arkansas summer made it impossible to run machinery. Even if the workers could tolerate… Continue reading

The Low Bid Will Cost You More

Are you tempted to choose the low bid for your HVAC project?​​ Consider this: If the electrical in your home or business goes to the low bidder, you may have fewer outlets and the cord for your vacuum may not reach this room or that corner. Maybe your light fixtures are junk and changing a light bulb becomes a pain. If your plumbing goes to the low bidder, you may need an extra water hose to reach the tree you just planted. Your tub or your sink may drain a little slower than you’d like and you may be replacing fixtures before you thought you should. But, if your heating and air-conditioning goes to the low bidder? Your system may not be installed correctly, sized correctly, or charged correctly. Your duct system may be a mess and your indoor blower may not be set to match the duct system and… Continue reading

SEER Ratings: Make the Right Decision

What does “SEER” mean? Homeowners and contractors, alike, are generally confounded by the SEER acronym. So, let’s start with the basics: SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER, the more energy efficient the air-conditioner. Ok, but how high is high enough? The reality is the answer provided to homeowners is almost always incomplete – and, thus, often incorrect. Think of it this way: The most efficient air-conditioner is one that isn’t running at all. The least efficient air-conditioner is one that runs continually and never adequately cools the home. In between, you will find shades of gray. How do I calculate which SEER rating is best for me?  SEER is a formula – and it’s not advanced level math. Just divide the system’s rated British thermal units (BTU) by the AHRI SEER rating and, like magic, you have the kilowatts per hour (KWH) for the unit.… Continue reading

HVAC 101: The Basics

​Not much beats stepping into an air-conditioned room on a hot day. But have you considered what’s happening inside of your home to keep it cool? A building’s air-conditioning is part of a larger system commonly referred to as its heating, ventilation, and air-conditioning system – HVAC for short. Your home’s HVAC system is essentially an expansive machine that consists of a ventilation system, a thermostat, and various devices that either heat or cool the air. Understanding the basics can be very helpful when trying to decide whether to repair or replace your unit. The following helps to break down what goes into keeping your home comfortable. Ventilation is Key The ventilation portion of your system is comprised of return and supply vents, ductwork, filters, and a circulating fan. The circulating fan pulls air from inside your home through the return vents, into the ductwork, and over the devices that… Continue reading

The Basement Bidder

Pop quiz: Can you name arguably the most unlikely source of sustainability for Air-Dynamics over the past two decades? Answer: the basement bidder. That might be surprising for obvious reasons, but, for a shop that has quite literally built itself from the ground up on positive word-of-mouth from satisfied customers, the basement bidder – the company that intentionally comes in well below market value to ensure that they win the bid – actually creates work for us. Why? C’mon, you know the answer to this. “You get what you pay for,” right? It’s true for vehicles, appliances, and fishing poles – and it’s also true for heating & air-conditioning systems. The work of that basement bidder will need to be repaired and/or replaced in embarrassingly short order, and that’s where we come in. The quality of our work speaks for itself, and that simple fact that we work tirelessly to… Continue reading

Bargain Hunters: A Lesson from Proverbs

There’s nothing wrong with a good bargain. However, not every bargain is always a “good” bargain. A buyer haggles over the price, saying, “it’s worthless,” then brags about getting a bargain. “It is naught, it is naught, saith the buyer: but when he is gone his way, then he boasteth” (Proverbs 20:14).  The new 410A environmentally friendly refrigerants operate at double the pressure of the old R22. The oil used is hydroscopic, meaning it absorbs moisture readily. Moisture is the enemy to the internal function of an HVAC system. While R22 required a 500-micron vacuum, the 410A requires a 300-micron vacuum. The deeper, longer vacuum requires equipment capable of handling the job. If the appropriate vacuum is not achieved, the system will run and act the same, but the lifespan of the equipment will diminish significantly. So when the technician drives away and you’re boasting that you got it cheaper…Did you? This… Continue reading
