Resolving an air conditioning problem quickly can help save you other repairs down the road. If you are unsure if you need AC repair we recommend calling an HVAC professional to look over your unit.
WHEN SHOULD I REPLACE MY AIR CONDITIONER?
The lifespan of most air conditioning systems is between 10 and 15 years. AC systems that have had regular maintenance performed tend to last longer than systems that have not had regular maintenance. If you are unsure if you need a new air conditioner we recommend calling an air conditioning professional for a free system replacement estimate. A licensed professional can work with you to determine the size and SEER of the unit that is right for your family.
HOW DOES SEER RATING WORK?
A SEER rating for an air conditioning system or heat pump measures its ability to cool your home as efficiently as possible. This is calculated by the cooling output divided by the total electrical energy input during the same time. The term SEER stands for seasonal energy efficiency rating.

MERV (Minimum Efficiency Reporting Value) rates the effectiveness of air filters in trapping airborne particles. Higher MERV ratings indicate better filtration, which can improve indoor air quality.
How often should I service my HVAC system?
It's recommended to have your HVAC system inspected and serviced at least twice a year. Ideally, schedule maintenance for your heating system in the fall and your cooling system in the spring to ensure optimal performance.
Where is my air filter located?
The location of your air filter can vary depending on your system's design. Common locations include:
• Inside the furnace or air handler unit
• Behind return air vents
• In a dedicated filter slot or compartment
How do I know what size filter to use?
The correct filter size is usually printed on the edge of the existing filter. If you're unsure, consult your HVAC system's manual or contact your dealer for guidance.
What does the Carrier warranty cover?
Carrier's warranty typically covers functional parts such as:
• Blower motors
• Compressors
• Coils
• Control boards
• Heat exchangers
• Non-functional parts like belts, fuses, and cosmetic components are generally not covered. For detailed information, refer to your warranty certificate or use Carrier's warranty lookup tool.
Why isn't labor covered under the warranty?
Carrier provides a limited parts warranty as the manufacturer. Labor coverage is typically offered by the installing dealer or contractor and may vary based on their policies.
Where can I find my system's serial number?
The serial number is located on the "rating plate" sticker of your unit.
• For outdoor units (air conditioners and heat pumps): It's usually on the back of the unit above the service valve connections.
• For furnaces: Open the front door panel; the sticker is typically inside.
What's the difference between standard and communicating thermostats?
Standard (non-communicating) thermostats control HVAC systems using basic on/off signals and may have limited features. Communicating thermostats, like Carrier's Infinity® System Control, enable two-way communication with the HVAC system, allowing for advanced diagnostics, energy management, and enhanced comfort control.
What are thermostat alert codes?
Thermostat alert codes notify you of system statuses or issues. They can indicate:
• Conditions: Informational messages, such as software updates.
• Faults: Issues that may require attention but don't immediately affect system operation.
• Malfunctions: Serious problems that may cause system shutdowns and require immediate service.
How do I know when it's time to replace my HVAC system?
Consider replacing your system if:
• It's over 8-15 years old.
• You're experiencing frequent repairs.
• Energy bills are increasing without changes in usage.
• There are inconsistent temperatures throughout your home.
Can I install an HVAC system myself?
HVAC installation involves complex procedures, including handling refrigerants and ensuring proper system sizing. It's strongly recommended to have a licensed professional perform the installation to ensure safety, efficiency, and warranty compliance.
How long does HVAC installation take?
The duration varies based on system complexity, but most standard installations are completed within one day. More complex setups or additional ductwork may extend the timeframe.
Where can I find manuals and technical documents for my Carrier equipment?
You can access owner’s manuals, installation guides, and product specifications by visiting Carrier’s Document Search page. Simply enter your model number to find the relevant documents.
How often should I replace my HVAC filter?
For one-inch thick filters, replace monthly. Two-inch or high-capacity pleated filters can be changed every other month or about six times per year.
What does the Carrier warranty cover?
Carrier’s standard factory limited warranty covers defects in materials and workmanship during the warranty period. It provides a new or remanufactured part at Carrier’s discretion, but does not cover labor. Your warranty certificate, included in your homeowner information packet, details the specific terms.
What are the benefits of a programmable thermostat?
Programmable thermostats can help save on energy costs by tailoring your heating and cooling system to your schedule, ensuring efficient operation when you're home and conserving energy when you're away.
What do thermostat alert codes mean?
Alert codes indicate various system statuses or issues. They can be categorized as: Conditions, which are informational alerts like software updates; Faults, which are issues that need attention but may not immediately affect operation; and Malfunctions, which are serious issues requiring immediate service.
What is the difference between variable-speed and two-stage systems?
Variable-speed systems operate in longer, lower-speed cycles, providing consistent comfort and energy efficiency. Two-stage systems have two levels of operation—high for extreme temperatures and low for milder days—offering improved efficiency over single-stage systems.
Why would I choose a heat pump for my home?
Heat pumps provide both heating and cooling, making them versatile for year-round comfort. They are especially efficient in moderate climates and can be an energy-saving alternative to traditional systems.
How can I assess the indoor air quality of my home?
Your Carrier dealer can perform an indoor air analysis, providing personalized results in approximately 30 minutes. This assessment can identify pollutants and help determine solutions to improve your home's air quality.
What does BTU stand for in HVAC terms?
BTU stands for British Thermal Unit. It's a measurement of energy, specifically the amount required to raise the temperature of one pound of water by one degree Fahrenheit.
Is it advisable to adjust my thermostat when I'm not home?
While setting back your thermostat can save energy, drastic changes might lead to discomfort and increased humidity or dryness. A moderate adjustment of 2–3 degrees is recommended. For extended absences, like vacations, more significant adjustments can be beneficial, but it's essential to consider potential impacts on home humidity and comfort.
Should I cover my outdoor air conditioning unit during winter?
It's not recommended to fully wrap your A/C unit, as this can trap moisture and invite pests, leading to potential damage. However, placing a cover over the top can protect against falling debris like leaves or icicles.
What benefits do electronic air cleaners offer?
Electronic air cleaners, such as the Aprilaire 5000, can capture up to 99% of airborne particles, including viruses and ultra-fine pollutants as small as 0.3 microns. This significantly improves indoor air quality compared to standard filters.
How does a UV purification system work?
UV systems sterilize airborne microorganisms, preventing them from reproducing. Once neutralized, these particles are captured by your HVAC system's filtration, enhancing overall air cleanliness.
When should I consider replacing my UV lamp?
Typically, UV-C lamps are effective for about 12 months. Some advanced models may last between 2 to 4 years. Regular replacement ensures optimal air purification performance.
What is the function of an air exchanger (HRV)?
An HRV system helps balance indoor humidity by expelling moist air and bringing in fresh outdoor air. It also tempers incoming cold air, ensuring your home remains comfortable even during colder months.
How can I determine if I need an air exchanger?
If your home has been sealed tightly for energy efficiency—through window upgrades or added insulation—you might notice increased indoor humidity or condensation on windows. An HRV can help by introducing fresh air and reducing moisture levels.
What maintenance services do you provide?
We offer a range of services, including tune-ups, diagnostics, and repairs for furnaces, air conditioners, heat pumps, humidifiers, dehumidifiers, air cleaners, UV purification systems, and more.
Are maintenance plans available?
