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.

With two-stage heating, furnaces may run on two different levels: high and low. Since you can heat your home on the low setting most of the time, a two-stage furnace can run longer and more efficiently. Two-stage heating also runs more quietly than traditional furnaces and can offer more even heat distribution and fewer temperature swings.
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.

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.

The Department of Energy recently boosted the minimum efficiency levels for air conditions, and the standards vary by region. Contact Klaus & Sons Heating & Air Conditioning at 909-982-5698 to find the requirements for the Upland area.

Heating and cooling makes up a huge portion of your monthly utility bill. Purchasing HVAC equipment with high efficiency ratings, such as SEER for air conditioners and AFUE for furnaces, is a simple step that can go a long way in decreasing energy output. Beyond these ratings, also think about:

  • Routine maintenance – regularly having a professional tune-up your equipment will keep it working at its greatest potential.
  • Adding a zoning system – by focusing your heating and cooling on the rooms you use most frequently, you won’t have to pay to heat or cool areas of your home that aren’t routinely used.
  • Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can lower heating costs by up to 35 percent and cooling costs by up to 25 percent. Leave it up to your thermostat to turn down the heat when you’re not around and bring it back up to your preferred temperature when you’re home.

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.

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.
Try using our Healthy Solution Finder, where you can pick the indoor air quality issues that affect your home. After you select the items that apply, the system will show the IAQ products that meet your needs. You can also call Klaus & Sons Heating & Air Conditioning and walk our techs through some of the concerns you experience. They can evaluate your home and needs and provide options and answers.
It may come as a surprise that air conditioners don’t technically make your home cooler; they actually remove the hot air and transfer it outside. This hot air is pushed across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner transfers as much hot air outside as is necessary to reach the temperature you have set on your thermostat.
Minimum energy efficiency standards vary by region. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than equipment manufactured prior to that date. The team at Klaus & Sons Heating & Air Conditioning can help you determine the minimum requirements for Upland, let you know if your current systems meets those requirements or help you find a replacement air conditioner that does.
Your system’s service panel has a white label on it, with your system’s model and serial numbers at the top. M/N stands for model number and S/N is the serial number.
Since equipment size needs differ for each home, the best way to determine the right size equipment for your home is to have a technician from Klaus & Sons Heating & Air Conditioning come out to perform load calculation tests. The tests take things like square footage, insulation value and amount, and more into account to determine your home’s individual HVAC equipment needs.
Yes – debris can affect your system’s ability to function effectively. It’s common for heat pumps to have frost or ice on them during the winter, but many include defrost controls so they can work efficiently regardless of the weather conditions.
When an air conditioner uses two-stage cooling, it means that there are two levels of operation. This enables the system to work as efficiently as possible since there is one level for milder weather and another for harsher weather that demands the system work harder. Two-stage cooling also enables slight temperature changes so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and enhanced humidity control.
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.
Klaus & Sons Heating & Air Conditioning carries a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on a variety of variables, such as whether you want one that’s programmable or not. No matter what kind of thermostat you’d like – or if you’re in the market for something that can fit with a home automation system – call Klaus & Sons Heating & Air Conditioning to hear about which thermostats you can choose from. Our team will help you find one that’s right for your system, your family’s needs and your budget.
A heat pump takes care of both your home’s heating and cooling needs, offering you one HVAC system that can be used year-round. Throughout the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and transferring it outside; in the cooler months, this process is reversed. Heat pumps can be very energy efficient and may produce two to three times more heat than the energy it uses.
At Klaus & Sons Heating & Air Conditioning, we do recommend replacing both your indoor and outdoor units at the same time because:
  • Outdoor systems are now built to work with their matching indoor system for the highest efficiency possible. When you replace just one of your systems, you may not see the same savings on your energy bills as if you had replaced them together.
  • Thanks to technological innovation, newer systems mean better efficiency. This is true for HVAC products as well. While the advancements focus on greater heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are over 10 years old, they need to be replaced. Older models have outdated technology that is likely costing you money due to poor efficiency. So by replacing your indoor system at the same time as your outdoor equipment, both your systems will provide better energy efficiency that helps you lower your energy bills and keep your home more comfortable.
Yes. Your SunSource® Home Energy System has a communication module that transfers the system’s performance data to a website. The website will show your system’s status, energy production and environmental benefits, as well as carbon offsets in real time.
Yes, you will need an Internet connection if you want to utilize the system’s online monitoring system. The system allows you to view energy production and environmental information. The monitoring service is provided free of charge for five years, and the performance-monitoring website is offered by an independent third party, Enphase Energy Inc.
Rain will clean the modules by itself in most areas; however, if you live in a dusty area, you may see improved performance after periodically spraying the modules with water. Please note that high-pressure hoses and detergents should never be used to clean solar modules, as they can damage the product.
Klaus & Sons Heating & Air Conditioning can help you find the right thermostat for you based on your home and current heating and cooling equipment. We carry a number of programmable and nonprogrammable thermostats, which can help increase the efficiency of your home’s furnace and/or air conditioner. Take a look at our thermostats or give us a call at 909-982-5698 for more information.
Your heating and cooling equipment can contribute significantly to your monthly utility bills. However, these costs can be decreased with innovative and high efficiency products from Lennox®. Keep an eye out for high SEER and AFUE ratings when you’re in the market for a new air conditioner or furnace, respectively, as higher SEER and AFUE ratings denote higher efficiency products. If you’re not looking for new heating and cooling equipment, consider factors such as: 1. Maintenance: Furnaces, air conditioners and other HVAC equipment operate more efficiently when they are regularly maintained. 2. Zoning: When areas of your home are rarely used, you’re spending more money to heat or cool them to the same temperature as the rest of the house. A zoning system enables you to section off different portions of your home and control the temperature by each area. 3. Programmable Thermostats: Programmable thermostats can help you decrease your heating costs by 35 percent and your cooling costs by 25 percent, according to the U.S. Department of Energy.
A zoning system enables you to parcel your house and heat or lower the temperature in each part differently. While these systems operate well for buildings that have parts that are rarely occupied, they can also be helpful in situations where you and your family argue about the temperature in different areas of your house. There are a number of additional pluses of zoning systems, such as efficiency and comfort.
