HVAC Frequently Asked Questions
What are the advantages of ductless HVAC technology and when should it be used?
Ductless HVAC technology offers many potential benefits for homeowners. Units can be zoned to maximize energy efficiency when cooling specific rooms or areas of the home. They provide a more energy-efficient alternative to traditional whole-home systems thanks to their design, the lack of energy loss via ductwork, and can help reduce heating and cooling bills. Overall, multi-zone ductless installations can be a strong option for homeowners seeking cost-effective and energy-efficient options for controlling the climate of their home. This technology is ideal for new home additions, converted attics and garages, outdoor guest cottages, and for retrofitting historical homes with no existing ductwork. A multi-zone system with several outdoor units also can be a viable and energy-efficient alternative to central air or heat pump, depending on the region.

What is a SEER rating and why is it important?
The cooling efficiency of your heating and cooling equipment is measured by the SEER (seasonal energy efficiency ratio) rating. This ratio represents how much cooling your system will provide for each dollar spent on electricity, compared to other systems. Higher SEER ratings represent more efficient systems. An HVAC unit’s SEER rating can range from 13 to 21, depending on a variety of factors. A SEER rating does not factor in the added efficiency that Daikin inverter compressors can provide when operating at less than full capacity.
Why is the SEER rating on the Energy Guide different than what my contractor quoted?
The nominal SEER rating for your split cooling system may not be the same as what you were originally quoted. This is because seasonal energy-efficiency can be increased by upgrading the indoor unit to another unit of the same series. Your overall SEER rating is determined by the combination of equipment installed. Both your outdoor equipment (such as a heat pump or air conditioner) and your indoor units (such as the air handler or furnace and evaporator coil), contribute to the total SEER rating.
Why should I have regular (or preventive) maintenance? And how often should I have it performed?
Regularly scheduled Preventive Maintenance is essential for your heating and cooling equipment. These sensitive systems work hard day-in and day-out to maintain your home climate. Continual operation – as well as frequent starting and stopping – can contribute to increased wear and tear on your home HVAC unit. Regular maintenance is essential for increasing the lifespan of your heating and cooling equipment, and it improves effective performance. Regular maintenance inspections can help identify major issues (including leaks, rot, soot, frayed wires, and corrosion) that can contribute to decreased performance and even equipment failure. Regular maintenance may also be required to receive the full benefits of your systems limited warranty. Schedule a preventive maintenance check with A to Z Heating & Cooling to ensure your equipment is operating in top condition and to help reduce future issues in your home heating and cooling equipment.
What equipment requires regular (or preventive) maintenance?
You should have your heating and cooling equipment tuned up by a professional annually in both the spring and the fall. If you have an air conditioner and heat pump, your service technician should inspect your fan, compressor, indoor and outdoor coils, and all refrigerant lines. For homes with boilers and furnaces, inspections should cover ductwork, pipes, dampers, valves, chimneys, registers, radiators, pumps, blowers, oil tanks, fuel lines, and all components of the boiler and furnace themselves. A full check of your systems is key for maintaining their performance in the summer and winter months and for maintaining the complete coverage of your systems limited warranty.

What are the advantages of a programmable thermostat?
Programmable thermostats offer a more accurate and efficient alternative to traditional mercury thermostats. Smart solutions empower homeowners to program their thermostats to meet their temperature needs throughout the day without ever having to touch the thermostat itself. Powerful apps are available for many solutions to empower remote control of your home climate. With the right programming, you can fully automate your home temperature routine for your convenience and comfort. Some smart home thermostats can help you save energy and may alert you or your Daikin contractor of potential problems with your system.
What type of filter should I use? And how often should I replace it?
While a standard air filter will do the basic work of keeping your ductwork and system clean, it will not improve your home’s indoor air quality. Many homeowners rely on media air cleaners to solve this problem. A media filter is situated between your main duct return and the blower cabinet to improve a standard air filter’s removal of dust and particulate matter by up to seven times. Beyond this, an upgraded pleated media filter can even remove viruses from the filtered air. Whatever solution you decide upon, you should always match your air filters to the capacity of your HVAC blower. To ensure optimized performance and air quality, we recommend replacing disposable filters monthly or cleaning reusable filters monthly as well.
Why can't I find the correct size furnace filter at my local home improvement store for my Daikin Brand Equipment?
Daikin is committed to providing high-performance HVAC equipment. Filters for your Daikin unit use high-quality materials not found in retail stores’ disposable filters. Because of this, replacement filters for Daikin equipment may only be available from certified Daikin contractors. Remember that some Daikin filters can be washed by hand in cold water for reuse.

What is the life expectancy of my unit?
Daikin products are known for their dependable performance and are one of the longest-lasting lines of heating and cooling products on the market today. Life expectancy for specific equipment models is affected by a variety of factors, including the completion of regularly scheduled routine maintenance.
How frequently should I schedule maintenance for my air conditioning system?
For optimal performance, it’s recommended to schedule maintenance for your air conditioning system at least once a year. Ideally, this should be done in the spring before the cooling season begins. However, if your AC system runs year-round or under heavy usage, twice a year (once before summer and again before winter) might be beneficial.
What indicators suggest that my air conditioning system requires repairs?
Here are some common indicators that suggest your air conditioning system may need repairs:
- Poor Airflow: Weak or inconsistent airflow could indicate a clogged filter, ductwork issues, or a failing compressor.
- Warm Air: If the system blows warm air instead of cold, there could be a problem with the refrigerant levels or a malfunctioning compressor.
- Unusual Noises: Strange sounds like grinding, squealing, or banging often signal issues with the motor or other internal components.
- Frequent Cycling: If your AC turns on and off more frequently than usual, it may be experiencing thermostat issues, electrical problems, or insufficient cooling capacity.
What steps can I take to enhance the efficiency of my air conditioning system?
To enhance the efficiency of your air conditioning system, follow these steps:
- Regular Maintenance: Schedule annual or bi-annual professional maintenance to ensure optimal performance and catch potential issues early.
- Change or Clean Air Filters: Replace or clean the air filters every 1-3 months, depending on usage. Clogged filters restrict airflow and reduce efficiency.
- Seal Leaks in Ductwork: Ensure that your ductwork is properly sealed to prevent air loss, which can make your AC work harder.
- Use a Programmable Thermostat: Set your thermostat to adjust automatically when you’re not home or during sleeping hours to reduce unnecessary energy consumption.

What are typical signs that my furnace might need repairs?
Here are common signs that your furnace might need repairs:
Insufficient Heat: If your furnace isn’t producing enough heat or is blowing cold air, it could indicate issues with the thermostat, pilot light, or blower motor.
Frequent Cycling: When the furnace turns on and off frequently, it may point to thermostat problems, clogged filters, or issues with airflow.
Unusual Noises: Strange sounds like banging, rattling, or squealing often signal loose or broken components inside the furnace.
How do I choose the appropriate size for a mini-split heat pump for my home?
To choose the appropriate size for a mini-split heat pump for your home, consider the following steps:
- Calculate the Room Size: Measure the square footage of the room(s) you want to heat or cool. Multiply the room’s length by its width to determine the total area.
- Determine BTU Requirements: Mini-split heat pumps are rated in BTUs (British Thermal Units). A general guideline is:
- 9,000 BTU for rooms up to 400 sq. ft.
- 12,000 BTU for rooms between 400-600 sq. ft.
- 18,000 BTU for rooms between 600-1,000 sq. ft.
- 24,000 BTU for rooms between 1,000-1,500 sq. ft.
- Consider Climate: If you live in a hot or cold climate, you may need a system with higher BTU capacity to maintain comfort during extreme temperatures.
- Factor in Room Features: Ceiling height, insulation quality, number of windows, and sun exposure all affect heating and cooling needs. Rooms with high ceilings, poor insulation, or many windows may require a larger unit.
