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, enabling your two-stage unit to run for longer periods of time. Two-stage units also provide more even heat distribution, fewer temperature swings, quiet operation, improved air filtration and energy efficiency.

Modern furnaces are developed with a host of innovative features older furnaces don't have. Todays heating systems provide 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 perk 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 run 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 A&M Heating & Cooling LLC at 520-200-1048 to find the requirements for the Tucson area.

A&M Heating & Cooling LLC carries a number of HVAC products with high-efficiency ratings, which can help lower the amount of energy they require to run. Aside from picking products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following:

  • Making certain that your system receives routine maintenance by a trained technician can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only targeted areas of your home, so you wont have to pay to heat or cool spaces that aren't used.
  • 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 desire when you're home and increase or decrease the temperature while you're not around, helping you save on utility costs.
A&M Heating & Cooling LLC is well-known in the Tucson area and you can rely on them to provide quality home comfort products. We offer a variety of innovative and high-quality products. We are dedicated to offering customers high-quality service and will make sure you find the best solution for your home.

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 increase 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 good for keeping your home warm in the winter and cool in the summer, but it also makes it difficult for airborne pollutants to escape. We have products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and regular 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 eliminating 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 recommend that you meet with one of the technicians at A&M Heating & Cooling LLC and have them perform an evaluation of your home and current indoor comfort system. We can help you determine which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your house, directing 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 cycle continues until the indoor temperature reaches the temperature you set on your thermostat.
Due to the 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 by region and carry varying requirements based on your location. A&M Heating & Cooling LLC 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 in the market for a replacement system.
These numbers can be found on a nameplate or sticker that is near your systems service panel. The sticker should be white with black letters and have both of these numbers located at 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 size a system is by having your local A&M Heating & Cooling LLC 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.
The short answer is Yes, because dirt and other debris can inhibit your systems ability to work efficiently. For heat pumps, it is not unusual to have frost or ice on them during the winter, but they also are built with defrost controls to ensure they work efficiently in that type of weather.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting starts up, and when its cooler or more mild, it operates on the low setting. Usually, 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 produce 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 couple 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 any homeowner take care of; however, you'll want to call the professionals at A&M Heating & Cooling LLC at 520-200-1048 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. Thats why its nice to have such a big variety of choices from A&M Heating & Cooling LLC. 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 choose from. Some thermostats will depend on what type of heating and cooling system you have, but the team at A&M Heating & Cooling LLC will be able to help determine what options are best for your needs and your budget.
Heat pumps can be a little confusing due to their name, but they actually meet both your heating and cooling needs all year. When its 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 could produce up to two or three times more heat than the energy it uses.
Of course we advise you to 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 part as a complete system, efficiency can be affected.
  • As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include better 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 feature outdated technology, but they are also less efficient than more recent 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 home energy system could send the system's performance records for each module to a website. You may visit this website to learn more about the system's status, energy production and environmental benefits. The site also shares carbon offsets as it happens.
In most locations, rain will clean the solar modules off automatically. If you live 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 rinse solar modules.
The proper thermostat for you depends on your heating and cooling equipment. A&M Heating & Cooling LLC offers programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 520-200-1048 to learn more.

Heating and cooling can make up a significant amount of your utility bill. The innovative and high-efficiency heating and air conditioning products available from A&M Heating & Cooling LLC can help reduce these costs. If you're looking 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 higher the number, the more efficient the product. Besides purchasing a new home comfort system, think about these additional factors:

  1. Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will work more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are spaces 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 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 portions of your house and control the air differently in each area. Zoning equipment is good for when you have parts of your residence that are seldom used or when you and your family are always in disagreement of what the temperature in each area of your home should be. Zoning systems are quiet and efficient, giving you more control over the comfort of your house. Discover more about the equipment available from A&M Heating & Cooling LLC.
