Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are developed to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.

Additionally, new furnaces are crafted to work with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers give your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help reduce noise associated with operating your equipment and easily meet your family's airflow needs.

The Department of Energy recently boosted the minimum efficiency levels for air conditioners, heat pumps and packaged units made after Jan. 1, 2015, since heating and cooling contributes significantly to a homes total energy usage. The requirements vary by region, so call Custom Air Systems Inc for the efficiency standards for Port St. Lucie.

Custom Air Systems Inc carries a number of HVAC products with high-efficiency ratings, which can help cut back the amount of energy they require to run. Aside from choosing products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you might consider the following:

  • Making certain that your system receives ongoing maintenance by a trained expert can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only targeted areas of your home, so you wont have to pay to heat or cool spaces that aren't used.
  • Using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programmed to give you the comfort you want when you're home and increase or decrease the temperature while you're not around, helping you save on heating and cooling costs.

Improving your homes indoor air quality starts with four basic strategies:

  • Poor indoor air quality leaves your home with lots of air pollutants floating around. So, to enhance IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this by cleaning and vacuuming at least once a week, frequently washing linens and storing cleaning products safely.
  • Proper insulation is ideal for keeping your home warm in the winter and cool in the summer, but it also makes it harder for airborne pollutants to escape. We have products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and ongoing cleaning are a start, but air filters, germicidal lights and purification systems take your IAQ to the next level by capturing microscopic particles, killing germs and getting rid of particles while destroying chemical vapors.
  • Programmable thermostats will help control the humidity levels and temperature to help prevent particles and germs from building up while also keeping your home comfortable.
We suggest that you meet with one of the experts at Custom Air Systems Inc and have them assess your home and current indoor comfort system. We can help you determine which equipment will be best suited to meet your needs.
Lots of homeowners believe that air conditioners make it cooler in your house, but it actually removes the heat from your home, sending the hot air outside. That hot air moves across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This process continues until the indoor temperature reaches the temp that was set on your thermostat.
Due to the amount of energy used by heating and cooling systems, the Department of Energy (DOE) increased the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined regionally and carry varying requirements based on your location. Custom Air Systems Inc can answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're searching for a replacement system.
These numbers can be found on a nameplate or sticker that is near your systems service panel. The sticker should be white with black letters and have both of these numbers located near the top of the sticker. M/N signifies model number while S/N is your serial number.
There are a handful of ways to determine what size system is right for your home, but the most reliable way to choose a system is by having your local Custom Air Systems Inc technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a variety of other factors.
The short answer is Yes, because dirt and other debris can hinder your systems ability to work efficiently. For heat pumps, it is common to have frost or ice on them during the winter, but they also are built with defrost controls to ensure they work efficiently in that type of weather.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting is used, and when its cooler or more mild, it operates on the low setting. Most of the time, the lower setting will take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can generate such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and enhanced humidity control.
When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can fix as a homeowner, but the others need to be done by a professional like those at Custom Air Systems Inc. Contact them at 772-247-2283 with any additional questions.
Choosing the best thermostat for your cooling system comes with a lot to think about. Thats why its nice to have such a big variety of choices from Custom Air Systems Inc. Whether you're searching for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the team at Custom Air Systems Inc will be able to help determine what options meet your needs and your budget.
Heat pumps can be a little confusing due to their name, but they actually cover both your heating and cooling needs all year. When its hot outside it works like an air conditioner in that it removes heat from your home, but when it cools off, the process gets turned around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and might produce up to two or three times more heat than the energy it uses.
Of course we suggest you also replace your indoor system, but this is why:
  • All outdoor cooling systems have a matching indoor unit that they are designed to work with to ensure efficient performance. When they aren't paired with the other part as a total system, efficiency may suffer.
  • As with most products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include improved heating and cooling efficiency, but also involve improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old usually need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than todays models. Adding a new indoor unit at the same time means you'll have a matched system to provide you with improved comfort and efficiency for years to come.
The communication module on your home energy system may send the system's performance records for each module to a website. You should visit this website to learn more about the system's status, energy production and environmental benefits. The site also displays carbon offsets as it happens.
In most areas, rain will clean the solar modules off automatically. If you live in a dusty or industrial area, periodically spraying the modules with water may help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules.
The proper thermostat for you depends on your heating and cooling equipment. Custom Air Systems Inc sells programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 772-247-2283 to learn more.

Heating and cooling can make up a big amount of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Custom Air Systems Inc can help decrease these costs. If you're shopping for a new heating or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of system efficiency, and the larger the number, the more efficient the product. Besides purchasing a new home comfort system, don't forget about these additional factors:

  1. Is your system typically maintained? Whether it's a furnace or air conditioner, HVAC systems will operate more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are spaces in your home that are rarely used, a zoning system will allow you to heat or cool only the most used areas of your house.
  3. Are you taking advantage of a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may decrease your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning your home allows you you the ability to section off portions of your house and control the temperature differently in each part of your home. These systems are best for when you have areas of your house that are rarely used or when you and your family are constantly in disagreement of what the temperature in each area of your home should be. Zoning systems are nearly silent and efficient, giving you more control over the comfort of your family home. Discover more about the zoning systems available from Custom Air Systems Inc.
