Two-stage heating permits the furnace to heat at two levels of output: high for cold winter days and low for mild ones. About 80 percent of the time, your homes heating requirements can be met when the furnace is set on the low setting, allowing your two-stage unit to run 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.

Modern furnaces are designed with a variety of innovative features older furnaces don't have. Todays heating systems offer more even heating and are better at controlling 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 work 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 American HVAC Inc at 408-215-1018 to learn the requirements for the San Jose area.

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

  • Making certain that your system receives regular maintenance by a trained expert can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only certain areas of your home, so you wont have to pay to heat or cool spaces that you aren't using.
  • Installing 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 need 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 filled with 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 challenging for airborne pollutants to escape. We carry products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and ongoing 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 stop particles and germs from building up while also keeping your home comfortable.
We suggest that you meet with one of the experts at American HVAC Inc and have them assess your home and current indoor comfort system. We can help you decide which equipment will be best suited to meet your needs.
Lots of homeowners believe that air conditioners make it cooler in your house, but it actually removes the heat from your home, 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 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) 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. American HVAC Inc can answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're looking for a replacement system.
These numbers are located 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 near the top of the sticker. M/N denotes model number while S/N is your serial number.
There are a few 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 American HVAC Inc technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a variety of other factors.
Yes, because dirt and other debris can impede your systems ability to work efficiently. For heat pumps, it is normal 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 its warmest, the high setting kicks in, and when its cooler or more mild, the low setting handles the duties. Most of the time, the lower setting can take care of your cooling needs, but even when the high setting is in use, 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 enhanced 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 homeowners take care of; however, you'll need to call the professionals at American HVAC Inc at 408-215-1018 for other problems or if you have other questions or concerns.
Identifying the best thermostat for your cooling system comes with a lot of considerations. Thats why its nice to have such a big variety of choices from American HVAC Inc. Whether you're in the market for for a programmable or non-programmable thermostat or want to join the smart home trend, there are various 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 American HVAC Inc will be able to help determine what options meet your needs and your budget.
Heat pumps can be a tad confusing due to their name, but they actually cover both your heating and cooling needs all 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 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.
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 created 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 many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These advances most importantly include improved 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 usually need to be replaced. Not only do they feature outdated technology, but they are also less efficient than newer 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 might send the system's performance records for each module to a website. You should 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 regions, rain will be enough to keep the solar modules clean. If you reside in a dusty or industrial area, periodically spraying the modules with water may help improve performance. However, detergents and high-pressure hoses should never be used to rinse solar modules.
The proper thermostat for you depends on your heating and cooling equipment. American HVAC Inc has programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Browse our available products or contact us at 408-215-1018 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 American HVAC Inc can help lower these costs. If you're shopping 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, consider these additional 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 rooms 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 equipment gives you the the comfort of sectioning parts of your residence and control the thermostat differently in each part of your home. Zoning tends to be good for when you have parts of your home that are seldom used or when you and your family are often in disagreement of how hot or cold it ought to be inside. Zoning systems are quiet and efficient, allowing you more control over the comfort of your family home. Discover more about the zoning systems available from American HVAC Inc.
