Why is regular maintenance important?

Like any product you want to keep in good shape, HVAC equipment requires proper care in order to deliver the best benefits. Trained experts can service your heating and cooling products to make sure they’re working at their greatest potential and help prevent more pricey repairs in the middle of the hottest or coldest months of the year.

What is two-stage heating?

Two-stage heating enables the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Around 80 percent of the time, your home’s heating requirements can be met when the furnace is left on the low setting, permitting your two-stage unit to operate for longer periods of time. Two-stage units also offer more even heat distribution, fewer temperature swings, quiet operation, better air filtration and energy efficiency.

How does Precise Comfort™ technology work?

Precise Comfort™ technology is an operating and control system used in Lennox furnaces. The technology can automatically adjust heat by increments as tiny as 1 percent, increasing energy efficiency and helping you experience more comfort.

How will my new furnace work differently from my old one?

Modern furnaces are designed with a variety of innovative features older furnaces don’t have. Today’s heating systems offer more even heating and are better at governing airflow. Although the air coming out of your vents may seem cooler than your old furnace, the airflow is much better and more efficient.

Another bonus of modern furnaces is their ability to operate with other HVAC products as part of a high-efficiency whole home comfort system. When combined with a high-efficiency air conditioner, furnace blowers can more easily accommodate add-on cooling. Other innovations, such as Precise Comfort™ technology and variable speed motors, will help your furnace operate more efficiently and quieter than ever.

How can I reduce my energy costs?

Lennox has a number of HVAC products with high efficiency ratings, which can help lessen the amount of energy they require to work40]. Aside from selecting products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can think through the following:

  • Maintenance – making sure your system gets regular maintenance by a trained expert can keep your system working at its top performance.
  • Zoning – zoning systems permit you to only heat or cool only specific areas of your home, so you won’t have to pay to heat or cool spaces that you don’t typically utilize.
  • Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to provide the comfort you desire when you’re home, and increase or decrease the temperature while you’re away, helping you save on heating and cooling costs.

Why should I buy from Lennox?

There are many reasons to go with Lennox, but the top three are:

  • Lennox is a name you know and trust – known across the world for quality HVAC products, you can rest assured Lennox will provide you with high quality equipment.
  • Innovative and high quality products – Lennox has been on the leading edge of innovation in the heating and cooling industry for years. High quality furnaces, air conditioners and home comfort systems include innovative features to help your home stay more comfortable and energy efficient.
  • Reputation of excellence – high quality products are not the only arena Lennox excels in. Lennox dealers, like Custom Sheetmetal & Roofing, Inc., give you high quality service at all times, from your first consultation to your scheduled maintenance appointments.

What can I do to improve my home’s indoor air quality?

Strategies to boost your indoor air quality can be as basic as vacuuming your home to something as large as replacing a new ventilation system. Overall, good IAQ has four strategies:

  • Eliminate – get rid of the pollutants floating in your air by cleaning your home regularly, particularly vacuuming carpet, washing linens and safely storing household chemicals.
  • Ventilate – make sure your home is well-ventilated to move airborne pollutants out of your home. In newer homes, well-done insulation will inhibit ventilation, so Lennox systems such as the Healthy Climate® ventilation system can help. These systems bring fresh air from outside into your home and direct the stale air out.
  • Clean – correct air filters, such as our Healthy Climate® air filters, will make sure the smallest particles don’t get through and are let out into your home. Germicidal lights can kill the germs that do make it through, and purification systems like the PureAir™ will help diminish odors and chemical vapors.
  • Monitor – keep your humidity levels in check with a programmable thermostat. High temperatures and humidity levels can raise concentrations of mold, mildew and germs. A programmable thermostat will make certain that your home is comfortable without letting humidity get out of control.

How does an air conditioner work?

Lots of homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from your house, sending the hot air outside. That hot air flows across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This procedure continues until the indoor temperature reaches the desired level that you set on your thermostat.

What is the minimum energy efficiency standard for air conditioners in my state?

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 by region and carry varying requirements based on your location. Custom Sheetmetal & Roofing, Inc. can 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.

What size equipment do I need for my home?

There are a couple ways to determine what size system is the best fit for your home, but the most reliable way to choose a system is by having your local Custom Sheetmetal & Roofing, Inc. technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a handful of other factors.

What is two-stage cooling?

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 it’s cooler or more mild, the low setting gets the job done. Typically, 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 also means a quieter cooling system, greater efficiency and improved humidity control.

Why is my system freezing up?

Your system could be freezing up for a number of reasons, but the most common are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something any homeowner take care of; however, you should call the professionals at Custom Sheetmetal & Roofing, Inc. at 785-357-6200 for other problems or if you have other questions or concerns.

What is the best thermostat to use for my cooling system?

Identifying the best thermostat for your cooling system comes with a lot to think through. That’s why it’s nice to have such a great variety of choices from Custom Sheetmetal & Roofing, 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 pros at Custom Sheetmetal & Roofing, Inc. will be able to help determine what options are best for your needs and your budget.

What is a heat pump?

Heat pumps can be a tad confusing due to their name, but they actually meet both your heating and cooling needs throughout the year. When it’s hot outside it operates 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.

When replacing the outdoor unit, should the indoor unit also be replaced?

Of course we think you should 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 unit as a complete system, efficiency might suffer.
  • As with a lot of products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These advances most importantly include greater 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 typically need to be replaced. Not only do they have outdated technology, but they are also less efficient than more recent models. Getting a new indoor unit at the same time means you’ll have a matched system to provide you with better comfort and efficiency for years to come.
