Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are designed 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 created to work with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer 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 decrease noise associated with operating your equipment and easily meet your family's airflow needs.

The Department of Energy recently increased the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after Jan. 1, 2015, since heating and cooling contributes significantly to a homes total energy usage. The requirements vary by region, so call Gilray Heating and Cooling for the efficiency standards for Wausau.

Gilray Heating and Cooling has a number of HVAC products with high-efficiency ratings, which can help cut back the amount of energy they require to work. Aside from choosing products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following:

  • Making certain that your system receives regular maintenance by a trained technician can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only specific areas of your home, so you wont have to pay to heat or cool spaces that you don't typically utilize.
  • 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 desire 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 full of air pollutants floating around. So, to improve 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 great for keeping your home warm in the winter and cool in the summer, but it also makes it difficult for airborne pollutants to escape. We offer products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and regular 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 avoid particles and germs from building up while also keeping your home comfortable.
We recommend that you meet with one of the technicians at Gilray Heating and Cooling and have them perform an evaluation of your home and current indoor comfort system. We can help you determine which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from inside your home, moving 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 the heat outside. This procedure continues until the indoor temperature reaches the temp that was set on your thermostat.
Due to the high 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. Gilray Heating and Cooling will be able to answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're in the market for a replacement system.
These numbers can be found on a nameplate or sticker that is near your systems service panel. The sticker will be white with black letters and have both of these numbers located around 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 will best suit your home, but the most reliable way to size a system is by having your local Gilray Heating and Cooling technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a handful of other factors.
The short answer is Yes. Dirt and other debris can hinder your systems ability to work efficiently. For heat pumps, it is not unusual to have frost or ice on them during the winter, but they also feature defrost controls to ensure they work efficiently in those kinds 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 kicks in, and when its cooler or more mild, it operates on the low setting. Usually, the lower setting will take care of your cooling needs, but even when the high setting starts up, you may not realize it because it can generate such even temperatures for your comfort. This also means a quieter cooling system, greater efficiency and improved humidity control.
When your cooling unit freezes up, there are a number of reasons why it could be doing so. The most common reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can change as a homeowner, but the others need to be done by a professional like those at Gilray Heating and Cooling.

Identifying the best thermostat for your cooling system comes with a lot to think about. Thats why its nice to have such a great variety of choices from Gilray Heating and Cooling. Whether you're in the market for for a programmable or non-programmable thermostat or want to join the smart home trend, there are a variety of thermostats that you have to pick from. Some thermostats will depend on what type of heating and cooling system you have, but the experts at Gilray Heating and Cooling will be able to help determine what options fit your needs and your budget.
Heat pumps can be a bit confusing due to their name, but they actually cover both your heating and cooling needs throughout the 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 reversed and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and may produce up to two or three times more heat than the energy it uses.
Of course we advise you to also replace your indoor system, but this is why:
  • All outdoor cooling systems have a matching indoor unit that they are intended to work with to ensure efficient performance. When they aren't paired with the other piece as a total system, efficiency can suffer.
  • As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These improvements most importantly include better heating and cooling efficiency, but also consist of improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old normally need to be replaced. Not only do they have outdated technology, but they are also less efficient than todays models. Getting 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 could send the system's performance records for each module to a website. You can visit this website to learn more about the system's status, energy production and environmental benefits. The site also shows carbon offsets as it happens.
In most locations, rain will clean the solar modules off automatically. If you reside in a dusty or industrial area, periodically spraying the modules with water could help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules.
The right thermostat for you depends on your heating and cooling equipment. Gilray Heating and Cooling offers programmable and nonprogrammable thermostats that can help increase the efficiency of your HVAC systems. Check out our available products or contact us at 715-301-0727 to learn more.

Heating and cooling can make up a large part of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Gilray Heating and Cooling can help reduce these costs. If you're looking 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, think about these additional factors:

  1. Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will operate more efficiently after regular maintenance checks.
  2. Do you need 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. Does your home have a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may lower your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning your home allows you you the opportunity to divide portions of your residence and control the air differently in each part of your home. Zoning equipment is best for when you have parts of your residence that are rarely used or when you and your family are constantly in disagreement of how hot or cold it ought to be inside. Zoning systems are quiet and efficient, giving you more control over the comfort of your home. Learn more about the zoning systems available from Gilray Heating and Cooling.
