Two-stage heating allows 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 kept on the low setting, enabling your two-stage unit to work for longer periods of time. Two-stage units also offer more even heat distribution, fewer temperature swings, quiet operation, increased air filtration and energy efficiency.
Precise Comfort™ technology is an operating and control system used in Lennox furnaces. The technology can automatically adjust heat by increments as little as 1 percent, increasing energy efficiency and helping you experience better comfort.

Modern furnaces are created 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 work 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 work more efficiently and quieter than ever.

The Department of Energy recently increased the minimum efficiency levels for air conditions, and the standards vary by region. Contact Clean Air HVAC at 925-233-6238 to find out the requirements for the Pacheco area.

Lennox has a host of HVAC products with high efficiency ratings, which can help cut back the amount of energy they require to run. 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 about the following:

  • Maintenance – making sure your system gets regular maintenance by a trained technician can keep your system operating at its best performance.
  • Zoning – zoning systems enable you to only heat or cool only certain 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 not around, helping you save on heating and cooling costs.

There are a number of reasons to choose 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 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 Clean Air HVAC, provide high quality service at all times, from your first consultation to your planned maintenance appointments.

Strategies to improve your indoor air quality can be as simple 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 often, 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 prevent 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 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 get rid of 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 utilizing our Healthy Solution Finder, where you can pick the indoor air quality problems that affect your home. After you pick the items that apply, the system will show the IAQ products that match your needs. You can also call Clean Air HVAC and walk our techs through some of the problems you experience. They can evaluate your home and needs and provide options and solutions.
Most homeowners believe that air conditioners make 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 the heat outside. This procedure continues until the indoor temperature reaches the temperature you set on your thermostat.
Due to the increasing amount of energy used by heating and cooling systems, the Department of Energy (DOE) raised 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. Clean Air HVAC can help 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.
You can find these numbers on a nameplate or sticker that is near your system’s service panel. The sticker is white with black letters and have both of these numbers located at the top of the sticker. M/N stands for 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 Clean Air HVAC technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a number of other factors.
Yes, because dirt and other debris can hinder your system’s ability to work efficiently. For heat pumps, it is common to have frost or ice on them during the winter, but they also feature defrost controls to ensure they work efficiently in those types of conditions.
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, 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 starts up, you may not realize it because it can produce such even temperatures for your comfort. This may also mean a quieter cooling system, greater efficiency and improved humidity control.
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 Clean Air HVAC at 925-233-6238 for other problems or if you have other questions or concerns.
Identifying the best thermostat for your cooling system comes with a lot to think about. That’s why it’s nice to have such a great variety of choices from Clean Air HVAC. Whether you’re searching 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 pick from. Some thermostats will depend on what type of heating and cooling system you have, but the team at Clean Air HVAC will be able to help determine what options fit 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 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 switched around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and could 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 intended to work with to ensure efficient performance. When they aren’t paired with the other part as a total system, efficiency can suffer.
  • As with most 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 include 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 today’s models. Buying 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 SunSource® Home Energy System sends the system’s performance records for each module to a website. You can visit this website to learn about the system’s status, energy production and environmental benefits. The site also shows carbon offsets in real time.
Yes, an Internet connection is needed for you to take advantage of the online monitoring system, which includes seeing energy production and environmental benefit information. The system’s performance-monitoring website is provided by an independent third party, Enphase Energy Inc., and the monitoring service is provided free of charge for five years.
In most locations, rain will naturally clean the solar modules. If you are located in a dusty or industrial area, periodically spraying the modules with water can help improve performance. However, detergents and high-pressure hoses should never be used to wash solar modules.
The right thermostat for you depends on your heating and cooling equipment. Clean Air HVAC offers programmable and nonprogrammable thermostats that can help improve the efficiency of your HVAC systems. Browse our available products or contact us at 925-233-6238 to learn more.
Heating and cooling can make up a significant portion of your utility expenses. The innovative and high efficiency heating and air conditioning products available from Lennox® can help decrease these costs. If you’re looking for a new heating and/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 higher the number, the more efficient the product. Besides purchasing a new home comfort system, consider these factors: 1. Is your system regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will work more efficiently after regular maintenance checks. 2. Do you need a zoning system? If there are spaces of your home that are rarely used, a zoning system will allow you to heat or cool only the commonly used areas of your house. 3. Are you using a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats could reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning equipment gives you the opportunity to divide parts of your house and control the air differently in each part of your home. Zoning tends to be best for when you have parts of your home that are rarely used or when you and your family are always in disagreement of the perfect temperature for the house. Zoning systems are almost noiseless and efficient, giving you more control over the comfort of your house. Learn more about the equipment available from Clean Air HVAC.
