- SMScott MillsFeb 17, 20265.0Prompt and professional service
- CPClifford PitzerFeb 16, 20265.0Not related to Heating and Air Conditioning but wanted to offer my thanks to the driver (did not get his name) who stopped on his own and assisted me with a flat tire in the Harrison City area. Likely an indication of the type of people that work for RJ Staso.
- CMChris MillerFeb 10, 20265.0Excellent!!!
- JCJason ClarkJan 23, 20265.0I had an excellent experience with RJ Staso Heating & AC. I called around 11am about a furnace issue and one of the owners personally answered the phone. After I explained what troubleshooting I had already done, they transferred me to another team member who was equally kind and thorough in gathering additional details. Even though I’m technically outside their normal service area, they were generous enough to waive the travel fee and, impressively, were able to get someone out the same day, just ahead of a major winter storm. Brent came out with the pressure switch replacement, arrived well within the quoted 12–4 window around 2, and got everything taken care of efficiently. From the first phone call to the completed repair, everyone I interacted with was professional, responsive, and genuinely focused on helping. I really appreciated how smooth and stress-free the whole process was. Highly recommend RJ Staso Heating & AC.
Frequently Asked Questions About R.J. Staso Heating & Air Conditioning
Do air conditioners dehumidify?
Air conditioners inherently remove some moisture from indoor air. Certain models enhance this effect through adjustable fan speeds and control of compressor or air conditioner stages. Dehumidification is a fundamental aspect of the air conditioning process.
What causes an air conditioner to freeze up?
Air conditioner freezing can occur due to several factors, including a blocked drain, dirty filter, obstructed coil, insufficient refrigerant, blocked vents, or a malfunctioning indoor fan motor.
Why is my air conditioner leaking water?
A leaking air conditioner is often caused by a clogged or partially blocked water drain from the indoor coil. Air conditioners primarily remove moisture from the air, so a dirty drain can result in leaks. Additionally, water leaks may occur due to ice buildup on the indoor coil, which can be caused by a dirty filter, blocked vents, low refrigerant levels, or a faulty indoor fan motor. When this ice melts, it can drip onto the floor inside the furnace or heat pump fan coil unit. Professional HVAC technicians can identify and address the source of the leak. If you're experiencing a leaking air conditioner, contact R.J. Staso Heating & Air Conditioning for assistance.
How many BTUs do I need for an air conditioner to cool my home?
Air conditioning systems are typically designed to provide cooling on a 95-degree day, which determines the BTUs required to cool your home at that outdoor temperature. Older air conditioner models operate at full capacity continuously, utilizing 100% of their electrical power when on, regardless of the actual outdoor temperature. This results in wasted capacity when temperatures are between 70 to 90 degrees. In contrast, newer models can adjust their output to provide only the necessary cooling, which reduces electricity consumption and lowers utility bills.
What is a ton of cooling?
A ton of cooling capacity equals 12,000 BTUs per hour. BTU, or British Thermal Unit, is a measure of heat energy, representing the amount of heat needed to increase the temperature of one pound of water by one degree Fahrenheit. The 12,000 BTUs per hour signifies the heat transfer rate required to melt one ton of ice at 32 degrees Fahrenheit over 24 hours. For example, a three-ton air conditioning system would provide 36,000 BTUs per hour. Air conditioning functions by transferring heat from inside your home to the outside using refrigerant.
Should I cover my outdoor air conditioning unit during the winter?
Covering your outdoor air conditioning unit is not always necessary, as these units are designed to withstand various weather conditions. However, if your unit is located near or under a tree, it's advisable to cover it to prevent debris accumulation during the off-season. When covering the unit, ensure that it's not completely sealed off. Allow some airflow at the bottom to prevent moisture from being trapped inside. Some homeowners place a piece of plywood on top of the unit to protect it from falling ice and deter rodents from entering. Always remember to remove any cover before using the unit again in the spring.
What is the difference between SEER and SEER2?
SEER (Seasonal Energy Efficiency Ratio) measures the cooling efficiency of an air conditioner or heat pump over a typical cooling season. It's calculated by dividing the cooling output by the energy consumed in Watt-Hours. SEER2 is an updated version of this measurement that incorporates the new M1 blower testing procedure. Both SEER and SEER2 ratings indicate energy efficiency, with higher ratings signifying more efficient systems and lower operating costs. According to the United States Energy Information Administration, 88% of homes have air conditioning. If your home lacks air conditioning, contact us to find the most suitable unit for your needs.
On my thermostat, what setting should my fan be on?
The 'automatic' setting on your thermostat activates the fan based on room temperature. If your home has an air cleaner or you prefer continuous airflow, set the fan to 'on'. Central air cleaning systems only operate when the furnace is circulating air, so keeping the fan 'on' maximizes your air cleaner's efficiency. This setting also helps maintain a more consistent temperature throughout your home. For further questions about air conditioning, please contact us.
What is an AFUE rating?
The Annual Fuel Utilization Efficiency (AFUE) ratio is used to evaluate furnaces. It indicates the percentage of heat generated for each dollar spent on fuel. Similar to a car's miles-per-gallon rating, a higher AFUE rating indicates greater efficiency and lower fuel costs. As a reliable HVAC company, we're here to address any questions you may have about your furnace.
How often should I have my furnace cleaned and serviced?
Based on our professional experience, we recommend annual cleaning and servicing for both your furnace and air conditioning unit. Regular maintenance ensures more efficient and cost-effective operation of your furnace. This service includes a comprehensive safety check of the entire unit, inspecting for any cracked, defective, or damaged parts. Damaged components could potentially lead to carbon monoxide leaks in your home, which can be hazardous and often go unnoticed. Contact R.J. Staso Heating & Air Conditioning today to learn more.
Does an air conditioner dehumidify the home?
Yes, every air conditioner will dehumidify a home to some extent as part of the cooling process, with some equipment enhancing this by adjusting fan speeds and compressor staging.
What can cause an air conditioner to freeze up?
Freezing can occur due to a clogged drain, dirty filter or coil, low refrigerant, blocked vents, or a defective indoor fan motor.
Why might my air conditioner be leaking water?
Leaks can result from a clogged water drain, ice formed by a dirty filter or coil, blocked vents, low refrigerant, or a defective indoor fan motor causing ice buildup and water dripping.
How do I determine the BTU capacity needed for my air conditioner?
Air conditioners are designed for 95°F outdoor temperatures; newer models stage cooling to match home needs, saving energy compared to older models which run at 100% capacity all the time.
What does one ton of cooling mean in air conditioning terms?
One ton of cooling equals 12,000 BTUs per hour, which is the heat transfer rate to melt one ton of ice at 32°F in 24 hours, describing the unit's cooling capacity.
Should I cover my outdoor air conditioning unit during winter?
Covering isn't always necessary, but if near trees, it's good to cover it partially to prevent debris. Covers should allow air flow and be removed before operation in spring.
What is the difference between SEER and SEER2 ratings?
SEER is the Seasonal Energy Efficiency Ratio measuring cooling output over energy use; SEER2 updates the calculation using a new blower testing procedure, with higher ratings indicating lower operating costs.
How should I set the fan on my thermostat?
The 'automatic' setting cycles the fan by room temperature, while 'on' runs it continuously, which is better for air cleaners and maintaining even temperature.
