Last week on the blog, we talked about the importance of choosing high quality copper refrigerant tubing insulation. Right now, one of the top choices for homeowners and home builders alike is insulation made from elastomeric foam. Elastomeric foam is an innovative material made of polymers that are simultaneously characterized by both viscosity and elasticity. Read on to learn why elastomeric foam tubing insulation is ideal for home builders.
Easing the Installation Process
For home builders, the installation process for foam tubing can sometimes be a challenge. However, the innate properties of elastomeric tubing make installation fast and easy. Here are a few reasons why most home builders prefer elastomeric foam over other types of foam insulation materials:
- Elastomeric foam is a flexible material, which makes it a lot easier to install than insulation made from stiffer foam materials. If you’ve ever spent excessive time trying to force a foam tube over a line, only to have the stiff foam crack in your hand, you know why flexible foam is ideal.
- At the same time, elastomeric foam is a tough material that is ready for on-site handling. As a home builder, you don’t want foam insulation that gets smashed upon the slightest contact with the tools in the back of your truck.
- You don’t have to worry about adding a vapor retarder. Elastomeric foam tubing has a built-in vapor barrier, which means you can skip that step in the installation process.
Ensuring Customer Satisfaction
As a home builder, customer satisfaction is one of your top priorities. Therefore, choosing high quality foam tubing insulation when setting up an HVAC system for your project just makes sense. Elastomeric foam tubing insulation, which is used to protect the copper refrigerant lines that run between the condenser and the evaporator coil of an air conditioning system, provided three key benefits for building owners:
- Preventing condensation that causes mold, which can be a major hassle for your customers to deal with.
- Reducing energy loss, which can help keep your customers’ regular energy bills low.
- Resisting ultraviolet radiation, which can ensure that your customers won’t have to deal with repairs or replacements for a long time.
For home builders, the choice is simple. With elastomeric foam tubing, you get an easy installation process and a lot of happy customers.

Last week on the blog, we talked about how helpful it can be to address issues with your air conditioning system in the fall, when issues are still on your mind after a long summer. When it comes to the functioning of your air conditioning system, the copper refrigerant lines that run between the condenser and the evaporator coil play an essential role. The larger of the two lines — known as the suction line — carries a cool gas, so it must be insulated with tubing. Read on to learn how the quality of this insulation can affect your HVAC system.
Protecting Copper Refrigerant Lines with Insulation
There are a few key problems that are associated with refrigerant line insulation, so it is essential to choose refrigerant tubing insulation that addresses these concerns. If you’re looking for tubing insulation for copper refrigerant lines, make sure it offers adequate protection against the following threats:
- Condensation. Whether your copper lines are located indoors or outdoors, the copper line will likely be exposed to air that is warmer than the refrigerant that it carries. When warm air hits the cool copper line, it can lead to condensation. If your insulation does not provide an adequate barrier between the air and the copper line, it can create a moist, humid atmosphere within the insulation tube that is an excellent breeding ground for mold. Therefore, you should look for insulation with a closed-cell structure that prevents warm outside air from reaching the copper line.
- Energy loss. Keeping the refrigerant in the suction line at a cool temperature is essential for maintaining the efficiency of the air conditioning system. The insulation basically acts like a thermos that keeps the refrigerant cool. If the refrigerant is exposed to warm outside air, more energy will be needed to keep it at the appropriate temperature. Again, choosing tubing insulation with a closed-cell structure can effectively guard against this problem and help keep your energy bills low.
- Ultraviolet radiation. If your copper line is located outdoors, it is essential to choose insulation that provides adequate protection against ultraviolet (UV) radiation. Even if the insulation is well-structured to prevent thermal energy losses and protect against condensation, long-term UV radiation can degrade the surface of the insulation and put your copper lines at risk. In order to avoid this hazard, you should look for tubing insulation that has been treated with a finish that is designed specifically to protect against surface degradation from UV exposure.

Now that summer is over and the weather is finally starting to cool off, it’s time to think back on your air conditioner’s performance over the last few months. One of the most important questions to ask is whether the cooling components in your AC system were sufficient to keep your house cool and comfortable all summer. If the answer is no, you may want to consider adding or replacing the cooling components in your system with a condenser with an evaporator coil.
Understanding How a Condenser with an Evaporator Coil Can Improve Your AC System
In an AC system, the condenser is responsible for releasing heat into the outdoor air. An evaporator coil picks up heat from the air inside your home or business, so choosing a condenser with an evaporator coil can increase the effectiveness and efficiency with which heat is removed from the building. As a result, adding or replacing a cooling component in your AC system with a condenser with evaporator coil can increase the system’s ability to keep your home or business cool during the hottest days of summer. This option is ideal for people who live in warmer climates and have AC systems that just aren’t meeting their cooling needs.
Of course, with winter on the way, improving your AC system might not be at the forefront of your mind right now. But fall is actually an excellent time to consider adding to or replacing cooling components within your AC system. If you live in a warm climate, waiting until spring can be risky. By the time spring comes and you remember that you wanted to improve your AC system, you might end up having to endure days without air conditioning while the condenser with evaporator coil is being installed. It can be a lot easier do the job now, when the sub-standard summer performance of your air conditioner is still fresh in your mind, but you don’t have to worry that your home will get too warm for comfort during the installation process.
Considering the Costs of a Condenser with Evaporator Coil
When deciding whether to invest in a condenser with evaporator coil, cost can be a major consideration. For one of these options, one of the main cost determinants is the cooling capacity, which can range from 1.5 tons to 5 tons. If you are worried about the effects of a condenser with evaporator coil on your energy bill, you should also pay attention to the SEER rating. For condensers with evaporator coils, you can choose between 14 SEER and 16 SEER. A higher SEER rating is generally associated with a higher upfront cost, but choosing a 16 SEER-rated product may help you keep next summer’s energy bills lower.

When you buy a new furnace or air conditioner, there are lots of parameters you need to consider. The AFUE and/or SEER rating or a system can help you find a system at your desired efficiency level, and the heating capacity gives you the information you need to ensure that the unit has what it takes to keep the temperature in your home or business at a comfortable level. Heating capacity is a measure of the amount of hot or cold air that the unit can produce, and it is measured in British Thermal Units (BTU).
If you’re a homeowner looking to replace both your furnace and air conditioner, or if you’re a homebuilder putting in systems for a new building, you might automatically assume that the BTU you need is the same for both the furnace and the air conditioner — but that’s not always the case. The main factor that determines your heating capacity needs is the size of the building, but other factors can lead you to choose a system that is on either the high or low end of the appropriate BTU spectrum for your building size.
BTU Ranges for Whole-Building HVAC Systems
If you are looking for an air conditioner or furnace to meet the cooling needs of an entire home or business, your heating capacity options vary widely. At the low end, you can buy a furnace or air conditioner with a 40K or 50K BTU. However, based on size alone, the heating capacity needs of most homes and businesses fall between 60K BTU and 100K BTU. For unusually large buildings, furnaces or air conditioners with 120K to 150K BTU may be required.
For every building size, there is a range of appropriate BTUs, which can be determined based on a variety of factors. Aside from size, some of the things that can cause your BTU needs to differ between your air conditioner and your furnace include the following:
- Location. If you live in a location that is cold for most of the year, with summer temperatures topping out around 80, you can get away with a lower BTU for your air conditioner than your furnace. Conversely, if you live in a warm location where the temperature never drops below freezing, the amount of heat to keep your house comfortable in the winter will be lower, so your furnace may not need as high a BTU as your air conditioner.
- Size and location of windows. East- and south-facing windows are great for keeping a building warmer in the winter, which may lower the necessary BTU. At the same time, if the windows are large and hard to cover in the summer, you may need an air conditioner with a higher BTU to keep the building comfortable in the warmer months.
- Personal preference. Regardless of the time of year, some people prefer a cool living environment, while others would rather stay warm and toasty. If you’re in the former group, it might make more sense to choose an air conditioner on the high end of the BTU spectrum for your building size and a furnace on the low end. If you’re in the latter category, the opposite strategy may be ideal for you.
