1” Pleated Filters: 30-45 Days
4” Pleated Filters
6 months: Single family suburban homes without pets

Replacing both systems at the same time can have long term benefits and can save energy and money over time. Mixing old and new technology can decrease system performance, while matched systems compliment each other for optimized energy efficiency and performance. Every home has unique needs, which is why we will work with you to figure out the best possible solution.

It’s a good idea to maintenance your HVAC systems by technicians every fall and spring to ensure peak performance all year long. The technicians will do routine tests to ensure proper functionality, as well as clean the wiring and mechanisms of the unit. Keystone Heating & Cooling offers a variety of service plans which include two equipment inspections per year.

When installing your new system, it is important to work with professionals who can guide you to the right product for your home. Properly functioning systems are more than just running effectively. Lack of heating or cooling can be attributed to a poorly insulated home or inadequately sealed doors and windows.

If your HVAC system seems to not be working properly, inspect and clean your air filters, check energy breakers in your home and check your thermostat functionality, inspect drain lines for leaking refrigerant and observe the unit for inconsistencies while running. If you notice severe problems, contact a Keystone Heating & Cooling technician right away.

Capacity is the ability of an HVAC system to heat or cool a given amount of space. In most cases, heating capacity is expressed in BTUs, or British Thermal Units. A BTU is the amount of energy needed to change the temperature of one pound of water by one Fahrenheit degree. Conversely, cooling capacity is specified in tons, or a measure of the system’s ability to cool. Manufacturers size heating and cooling systems according to their tonnage, with one ton being equal to 12,000 BTU/Hour. Most residential systems range from one to five tons. To properly size your HVAC Systems, our professionals will provide a HVAC Load Calculation with Every Estimate.

When it comes to choosing an HVAC system for your home, size really does matter. A unit that’s too small won’t cool your house properly, and a unit that’s too big will cost more than necessary.  It is important to install equipment with a capacity that matches the home’s size. Over time, this will decrease energy usage while improving comfort for you and your family.

If your system is giving you problems and it is more than 10 years old, it is probably lacking the latest energy efficient technology and it would be wiser in the long-term to replace it. Also consider the cost of repairs and how many more you will you need in the future.

Cooling Questions

Central air conditioning systems have two main components: the indoor unit and the outdoor unit. Together, they work to keep your home comfortable throughout the year.

Energy efficiency ratio, and seasonal energy efficiency ratio, are the calculations of how energy efficient the air conditioner is during the cooling season at varying temperatures. The higher the rating, the more energy efficient a unit is.

Heating Questions

While single and two-stage (Stages are Gas related) HVAC equipment can be effective, variable-speed technology presents consumers with a higher level of energy efficiency. Variable speed refers to a furnace’s or air handler’s indoor blower motor. Different speeds control the airflow in your home. Variable speed blowers automatically change speeds to meet the different airflow needs of the heating and cooling cycles. Variable speed motors can use significantly less energy and are excellent for customizing comfort levels in different areas of your home. A variable speed motor can also help clean the air and control the humidity. So while they are not necessary, they provide a variety of benefits to consider.

On average a PSC MOTOR (PERMANENT SPLIT CAPACITOR) will cost the home owner $350-$400 per year to run.

The Variable Speed motor on average will cost much less, typically $50-$60 per year.

During cold winter months, dry air can aggravate respiratory problems and allergy symptoms for many people. Whole-house humidifiers are permanently installed with your central heating and cooling system, regulating the humidity levels within your home, leaving you feeling comfortable all year long. In addition to only needing minor maintenance, they pull water directly from your household water system, making them a convenient, economic and health-conscious choice.

We recommend average cooling settings during warmer months to range from 72-80 degrees. Normal heating settings range from 68-62 degrees. To ensure energy efficiency, always set your thermostat to the highest possible comfortable setting in the summer and the lowest comfortable setting in the winter.

Two-stage heating systems provide a flexible way to utilize heating systems during colder months. They provide high heating options for colder days and low options for milder days. Two-stage units provide even heat distribution throughout the house and are able to run for longer periods of time since they can easily adapt to fluctuating temperatures. 1st Stage (high) Gas output and 2nd Stage (low) Gas Output.

There are many benefits associated with programmable thermostats to consider when purchasing a new system. They provide precise control over your heating and cooling to reduce wasted energy. The latest technologies include remote programming and price calculations prior to adjusting temperatures.
