Why does my home comfort system need regular maintenance?

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

What is two-stage heating?

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

What is Precise Comfort™ technology?

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, improving energy efficiency and helping you experience more comfort.

Will my new furnace work differently than my old one?

Modern furnaces are created with a number of innovative features older furnaces don’t have. Today’s heating systems provide more even heating and are better at regulating 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 benefit of modern furnaces is their ability to integrate 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 offers a variety of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to operate40]. 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 receives regular maintenance by a trained technician can keep your system working at its peak performance.
  • Zoning – zoning systems permit you to only heat or cool only targeted areas of your home, so you won’t have to pay to heat or cool spaces that you use infrequently.
  • Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to give you the comfort you desire when you’re home, and increase or decrease the temperature while you’re gone, helping you save on heating and cooling costs.

Why should I buy a Lennox product?

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

  • Lennox is a name you know and trust – known throughout 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 at the forefront 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 Klaus & Sons Heating & Air Conditioning, give you high quality service at all times, from your first consultation to your routine maintenance appointments.

How can I improve my home’s indoor air quality?

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

  • Eliminate – decrease the pollutants floating in your air by cleaning your home routinely, 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 – proper air filters, such as our Healthy Climate® air filters, will ensure even 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 increase concentrations of mold, mildew and germs. A programmable thermostat will ensure your home is comfortable without letting humidity get out of control.

How does an air conditioner work?

Many homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from your house, moving the hot air outside. That hot air goes across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This cycle continues until the indoor temperature reaches the temp that was set on your thermostat.

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

Due to the increasing amount of energy used by heating and cooling systems, the Department of Energy (DOE) hiked up 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. Klaus & Sons Heating & Air Conditioning 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 searching for a replacement system.

What size equipment do I need for my home?

There are a handful of ways to determine what size system is right for your home, but the most reliable way to determine the right size system is by having your local Klaus & Sons Heating & Air Conditioning 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 its hottest, the high setting kicks in, and when it’s cooler or more mild, the low setting handles the duties. Typically, the lower setting can take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can maintain such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and enhanced humidity control.

Why is my cooling unit freezing up?

Your system could be freezing up for a variety of reasons, but the most frequent are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something you, the homeowner, can take care of; however, you’ll need to call the professionals at Klaus & Sons Heating & Air Conditioning at 909-982-5698 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 Klaus & Sons Heating & Air Conditioning. Whether you’re looking for a programmable or non-programmable thermostat or want to join the smart home trend, there are a number of thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the experts at Klaus & Sons Heating & Air Conditioning 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 bit confusing due to their name, but they actually cover both your heating and cooling needs throughout the year. When it’s 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 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 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 unit 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 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 usually need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than more recent 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.
