2020 Residential & Commercial Tax Credit Reinstatements

With the recent signing of the funding bills, H.R.1865 (Further Consolidated Appropriations Act) and H.R.1158 (Consolidated Appropriations Act), the residential energy efficiency tax credit and Section 179D deductions for commercial buildings have been reinstated through 2020, after having previously been expired in 2017. So, how do these reinstatements impact you? Tax Credits and Deductions for Energy Efficient Homes and Commercial Buildings Improving a home’s energy efficiency has become an increasingly important factor for both home owners and contractors. With the reinstatement of the residential energy efficiency tax credit in Section 25C of the Federal Tax Code, tax credits can be offered to individuals who have improved the energy efficiency of their homes. According to the ACCA, “for qualified HVAC improvements, homeowners may be eligible to claim 25C tax credits equal to 10 percent of the installed costs, and a maximum credit of $500.” When it comes to commercial buildings, tax… Continue reading

Load Calculations 101: Understanding the Basics

At Air Dynamics, we want you to be informed on all of the ins and outs of the HVAC business to help you make the best decisions for yourself and home. When it comes to purchasing a new HVAC system, one of the most important details to consider is the size that will be needed. This is where load calculations come into play. What are load calculations? In HVAC terms, a “load” is how much heating or cooling a home needs. Therefore, a load calculation is the process of determining the right-sized HVAC system that will best heat or coola home. Why are they important? From footage size to insulation levels, every home is different. If you pick a system that is too big or small for your home, several issues can occur. These issues include: Uncomfortable Temperatures: Oversized and undersized systems can either put out too much or not… Continue reading

The R-22 Phaseout: What You Should Know

The phaseout of R-22 will soon be approaching a new stage on January 1, 2020. This stage will ultimately initiate the stoppage of production and importation of R-22. While you’ll still be able to use your R-22 air conditioners, there are several factors (rising cost, replacements) to consider. We want our customers to be well-informed of these changes, in order to make educated decisions for the future. In Why the Cost of R-22 Increased? , we first learned about the R-22 phaseout and discovered why the costs were increasing. For more information on what to expect during this phaseout and how you can better prepare yourself, please click the image below: Continue reading

The 6 Biggest Mistakes That HVAC Contractors Make

Believe it or not, heating and air-conditioning contractors are not super heroes. We just play them on TV. Mistakes are made—and those mistakes often hurt performance and efficiency of the systems being installed and maintained. Sometimes, those mistakes hurt the customers. And, sometimes, they even hurt the business. At Air-Dynamics, we don’t run from mistakes. Instead, we seek to identify the most common errors and aggressively meet those challenges head on, so as to ensure that we are always the overachieving exception rather than the underachieving norm. The following are the seven biggest mistakes we see being made throughout the industry: 1. Misunderstood combustion safety If an HVAC contractor responds to a call about carbon monoxide, they’ll usually go straight to the furnace and look for cracks in the heat exchange. If and when they’re unable to locate said crack, they often figure everything is on the up and up. So, instead, they simply… Continue reading

Oversized HVAC Equipment: 5 Reasons Why It’s A Problem

As we’ve touched on in the past, the HVAC system has become a problem source for home efficiency, and oversized HVAC equipment is a problem with consequences that, perhaps, are not being adequately communicated. Here are five reasons why oversized HVAC equipment is no good: 1. Dollars & Cents Oversized HVAC equipment has a higher initial cost and costs more to operate. That’s because the system runs in short bursts, which is about as inefficient as the rush hour stop-and-go routine is on your car’s fuel mileage. Longer run times reduce cycle losses and bolster efficiency. It’s also just plain hard on your stuff. An oversized compressor is destined for a short life. 2. Comfort Oversized equipment causes temperature swings. Shorter cycles leave your system playing catch-up—particularly along the perimeter of your home—because, by the time your thermostat feels the change in temperature, the temperature has dropped or risen several… Continue reading

Energy Efficient HVAC? It’s More Than Just A Box

Is your home energy efficient? Sure, you’ve got the energy efficient appliances. You’ve got the energy efficient light bulbs. You’ve even got green ethernet for crying out loud. But what about the single largest energy-user in the house? Your HVAC system. Even with the very best home construction and design — and even that fancy schmancy refrigerator — if a qualified HVAC contractor hasn’t been consulted with regard to the efficiency of your unit relative to the uniqueness of your home, you’re probably spinning your wheels… and your electricity meter. So, how’d this happen? How’d we get to a place where windows and washing machines are more highly scrutinized than your home’s air conditioner? The short story is this: The pioneers of energy efficiency came primarily from government-funded weatherization programs around four decades ago. Others began with solar water heaters — a result of the 1978 federal tax credit. And,… Continue reading

What Is The Recommended Humidity For My Home?

When it comes to indoor humidity levels, everyone has their own preference for what feels most comfortable. Generally, a relative humidity level from 35-50 percent is optimal for comfort — not to mention preventing the growth of microorganisms. Ideal Indoor Relative Humidity Levels by Outdoor Temperature Depending on personal preferences, the most comfortable indoor humidity level will vary from one household to the next. The following temperatures will give you a general idea of where to keep your indoor relative humidity levels: • For outdoor temperatures over 50 degrees Fahrenheit, indoor humidity levels shouldn’t exceed 50 percent. • For outdoor temperatures over 20 degrees, indoor humidity levels shouldn’t exceed 40 percent. • For outdoor temperatures between 10-20 degrees, indoor humidity levels shouldn’t exceed 35 percent. • For outdoor temperatures between 0-10 degrees, indoor humidity levels shouldn’t exceed 30 percent. • For outdoor temperatures between -10-0 degrees, indoor humidity levels shouldn’t… Continue reading

3 Reasons to Consider Buying a New Air Conditioner in the Fall

With temperatures dropping, your air conditioner is likely the last thing on your mind. What many homeowners don’t know is that fall is an ideal time to purchase a new air conditioning system. Below are a few advantages to buying a new air conditioner now instead of waiting until next cooling season, along with tips for protecting your unit at winter approaches. Avoid installation delays. The average lifespan for an air conditioning system is approximately 15 years, although it can vary based on usage, maintenance, and environmental factors. If your current air conditioner is nearing or past this mark, you should probably expect to replace your unit in the next few years, if not sooner. Purchasing a new system now instead of waiting will prepare you for next cooling season, and set you up for lower cooling bills. When you buy an air conditioner in the summer months, you may… Continue reading

When Should You Schedule a Preseason?

The concept of a “preseason” can be misleading. Preseasons are, more often than not, a ploy by the air-conditioning industry utilized as a means for giving their technicians something to do during the slow periods during the year. And, while it’s not necessarily a bad thing to get ahead of the game — especially at a discount — the outdoor temperatures prior to the season may be outside the parameters needed to accurately check the refrigerant charge in your air-conditioner. If it’s too cool outside and there is no load “cool inside” your house, the saturation temperature may be too low and the load on the equipment too low to accurately check your refrigerant charge. If the system doesn’t have a history of refrigerant leaks, then a glance may be adequate and you may also be able to include a furnace/heat pump maintenance thanks to the mild temperatures — the… Continue reading

How to Keep Cooling Costs Down During the Summer

Keeping cooling costs manageable during the dog days of summer can be a challenge. Here are a few tips to keep your checking account from feeling the heat. Change the filter often. Very few duct systems are air tight. The increased resistance caused by a dirty filter can make your air-conditioner pull in more air through any cracks and crevices in the return air duct system. If your return is in the attic, that means it’s pulling in extremely hot air. Keep your condenser coil clean. The condenser coil outside is where your air-conditioner gets rid of the heat it absorbed inside of the home. Having your unit washed regularly increases the efficiency of your air-conditioner. Also, keep shrubs, grass and leaves away from the outdoor unit. Reroute your dryer vent. You can’t fix stupid—but you can reroute it. If your dryer vent is close to or blowing on your… Continue reading
