Efficiency standards, refrigerant requirements, product availability, and savings estimates can change over time. Confirm current requirements and equipment information with a qualified HVAC professional.
What is the average life expectancy of equipment?
Many heating and cooling systems have a service life of about 10 to 15 years, though it varies with the equipment and how it is used and maintained. As a system ages, efficiency may decline and repairs may become more frequent. When considering an older system, compare the cost of repairs or an overhaul with replacement; an estimate can help you evaluate the options.
Can I just replace the outdoor unit on an older system to save money?
Outdoor units are designed to work with compatible indoor components. Replacing only the outdoor unit can affect system performance, and warranty requirements vary by equipment. Have a qualified technician check compatibility and the manufacturer’s terms before deciding.
Will a bigger sized system perform better?
Not necessarily. An oversized air conditioner can cool a home quickly but may run for too little time to remove humidity effectively. Frequent short cycles can also use more energy and add wear. Oversized heating equipment may cause temperature swings. Proper system sizing depends on the home.
Why is a system with matched components so important?
Matched components are designed to operate together. Correct sizing and compatibility can support appropriate cycle times, Komfort, humidity control, and efficiency. A load calculation helps determine the heating and cooling capacity a home needs.
How often should I change my air filter?
Replace the air filter regularly. How often depends on the filter type, pets, and the equipment. Follow the filter manufacturer’s instructions, and ask a technician for equipment-specific guidance.
Why should I switch to a high efficiency air filter?
A suitable filter helps capture dust and other particles moving through the system. Filter performance varies, and a filter must be compatible with the equipment; ask a technician if you are unsure which type to use. Change it regularly according to its instructions.
Should I have my furnace and air conditioner serviced every year?
Regular maintenance can help maintain system performance and identify developing issues. Maintenance needs vary by equipment and use; ask Komfort Kings about current service options.
Why should I purchase a service agreement?
A service agreement may cover maintenance or other specified items, but coverage varies and no agreement covers every possible problem. Review the current terms carefully so you know what is and is not included before purchasing.
How can I reduce allergens and improve the air quality in my home?
Air cleaners and whole-home humidifiers are among the indoor-air-quality options discussed for a home. What is suitable depends on the building and HVAC equipment. Ask a qualified professional about compatible options; these products are not a substitute for medical advice.
I am concerned about mold growth, what should I do?
Mold can grow where moisture is present. Keeping HVAC condensate drainage clear and maintaining equipment can help address moisture associated with the system, while filtration may reduce some airborne particles. If you suspect indoor mold or a moisture problem, address the moisture source and consult an appropriate qualified professional; HVAC equipment is only one possible contributor.
What do SEER, AFUE, and HSPF ratings mean to me?
SEER describes seasonal cooling efficiency; AFUE is a furnace fuel-use efficiency rating; HSPF describes heat-pump heating efficiency. Rating labels, minimum standards, products, and savings figures change over time. Compare current equipment labels and requirements with a qualified HVAC professional.
How can I reduce my energy costs?
Keep supply and return vents unobstructed, maintain equipment as recommended, and use thermostat schedules or settings that remain comfortable. Ceiling fans and equipment upgrades may also be worth considering. Actual energy use and savings depend on the home, equipment, and how it is operated.
Why should I buy Energy Star labeled equipment?
ENERGY STAR is a U.S. EPA and Department of Energy program that identifies products meeting its energy-efficiency criteria. Requirements and product labels can change, so check current ENERGY STAR information when comparing equipment.
What is a Heat Pump?
A heat pump can provide both heating and cooling by moving heat. In cooling mode it works similarly to an air conditioner; in heating mode it reverses the process to move heat indoors. System design and any backup heat depend on the home and equipment.
What are the advantages of equipment with variable speed fans?
Variable-speed fans can adjust airflow to system demand. Depending on system design and operating conditions, this may affect Komfort, humidity, noise, and energy use.
How does 2-stage heating or cooling work?
Two-stage equipment can operate at lower or higher capacity depending on demand. Different systems use different compressor or burner designs; available configurations and operation depend on the specific equipment.
At what temperature should I set my thermostat?
In summer, use the highest cooling setting that is comfortable; in winter, use the lowest comfortable heating setting. The best setting depends on your Komfort and circumstances, and any energy savings will vary.
My system doesn't work well in a couple of rooms, what should I do?
Uneven sunlight, system sizing, airflow balance or blockage, and a single system serving a two-story home can all contribute to uneven temperatures. The cause varies; an on-site assessment may be needed to recommend a solution.
Is Freon as a refrigerant being discontinued?
R-22 and R-410A have been discussed in older refrigerant phaseout information, but refrigerant rules and available products have changed over time. Ask a qualified technician about the refrigerant in your system and current requirements.
My air conditioner is very loud when I entertain outside, what can I do?
Equipment sound can be compared using published decibel ratings, although the sound you hear also depends on the equipment and surroundings. Ask about current models and their specifications when comparing options.
Can carbon monoxide build up in my home?
Yes. Incomplete combustion of fuels can produce carbon monoxide, so carbon monoxide detectors are important. If an alarm sounds or someone feels unwell, leave the home and seek emergency help from a safe location. Do not rely on HVAC troubleshooting to diagnose possible exposure.
What if I smell gas?
Leave the home immediately. Do not light matches, start engines, use a phone, or do anything that could create a spark inside. From a safe location, contact 911 and the gas utility or propane supplier. Do not return until authorities say it is safe. Shut off the gas supply only if you can do so without delaying evacuation or putting yourself at risk.
