How are the sizing capacities of heating and cooling systems measured?

The heating and cooling systems are sized according to their tonnage. One (1) ton equals 12,000 BTU/H. Residential systems can range from 1 to 5 tons.

What size HVAC system should I have?

Contrary to popular belief, there is no rule of thumb for sizing a system to a home. Depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to insure the size of the system you purchase will be large enough to cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional.

How is the efficiency of heating and cooling equipment measured?

The S.E.E.R. (seasonal energy efficiency ratio) is the amount of cooling your system will deliver per dollar spent on electricity. For example, a 3-ton unit may have a S.E.E.R. efficiency rating of 13, 14, 15, 16, 18 or 20. The higher the S.E.E.R. the more efficient the system will be. The S.E.E.R. rating of any given unit currently can range anywhere from 13 to 20.

How can I increase the efficiency and life of my home’s heating and cooling systems?

The most important thing you can do is clean and replace your filters frequently. Also, a system heats and cools more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home, and allows for better filtration. Finally, shades, drapes, shutters, or screens should be installed on windows that are exposed to extreme sunlight.

Is a system with more capacity “the bigger the better” always better?

No. A larger system with more capacity delivers less comfort and costs more to operate. An air conditioner is at its least efficient when first turning on. A system with too much capacity will run in numerous short cycles, turning on and off repeatedly, therefore causing it to be less efficient. Also keep in mind that an air conditioner only removes humidity when it’s running, so a system with shorter run cycles doesn’t remove humidity from the air very well.

How long should my system run in a cycle?

There is no exact answer for how long your system should run during each cycle. The average air conditioner is sized to remove the heat from your home as fast as it comes in, on a 110° day. Therefore, ideally, on a 110° day the system should be able to keep up with the incoming heat, but not gain on it and be able to turn off. The cooler it is below 110°, the more the system will cycle on and off.

Should I try to keep my system from running too much?

Every time your system starts up, it will use a lot of electricity and not produce much cooling. Usually a system that is too small to cool the home is more economical to run but delivers less comfort. Even though it runs nonstop, it will usually consume less power than a larger system that cycles on and off. As a rule of thumb, a unit that is either on or off is less expensive than one cycling on and off.

What air temperature should my air conditioner produce?

The air temperature your system produces depends on the temperature of the air going into the system. Generally, the air produced should be 18°-20° below what enters the system. So if the air entering the system is 80°, the air exiting should be about 60°-62°. However, that only works on a system that has been running at least 15 minutes on a warm, dry day with a home that is about 80° inside. On a mild day, with an indoor temperature in the low 70’s, or during humid conditions, the air coming out may only be 15°-17° cooler than what enters.

What temperature should I set my thermostat?

Obviously the time of year becomes a big factor for desired temperature settings. In the summer months the average temperature setting is 78°-80°, in the winter 70°-72° seems to be the most common setting. Remember, when leaving your house, try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.

What are the advantages of a programmable thermostat?

Different programmable thermostats offer many different features. However, because they are electronic, they are all more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

How often should I replace my filters?

For optimum efficiency and filtration, we recommend that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

What maintenance should I do on my air conditioner?

The most important maintenance you can do is to change your filters regularly. Outdoor units need to be kept clear of debris, clutter; weeds or landscaping that can grow too close and reduce the airflow to the unit. Also, keep pets away from the unit because pet urine can cause expensive damage. Use caution with a weed trimmer around the unit to prevent damaging control wiring. Any additional maintenance should only be performed by qualified personnel twice a year.

How often should I have maintenance done on my air conditioner?

You should have maintenance done on your air conditioning system twice a year. This not only ensures maximum efficiency, it enables us to foresee any possible problems that may occur in the near future. Our Preventative Maintenance Program is specifically designed to keep your air conditioning system running at its peak efficiency year-round.

Is there anything I should check prior to calling for service?

Yes. Check to be sure that the air handler or furnace is plugged in. Check that the breakers and the disconnects are turned on and be sure the thermostat is set correctly.

How much does a new replacement system cost?

Due to the many different makes, models and customer needs, price is an issue that can only be solved by doing a thorough evaluation of your home and existing equipment. There is no charge for an in-house replacement proposal.

Are there any air conditioning systems that are safe for the environment?

Yes. All manufactures have now developed new systems that contain the environmentally friendly R410A refrigerant, which meets EPA standards and is completely safe for the environment.

Do electronic air cleaners really work?

Yes, they can actually play a big part in your complete home comfort. We have a variety of whole-house filtration devices. Some electronic air cleaners can even remove dust particles and pollen as small as .10 micron.

Should I close the registers and doors to areas of the home that I do not use on a regular basis?

No. Closing the registers will decrease the systems’ airflow and efficiency. Every system is designed to cool a certain number of square feet. By closing registers and doors in certain rooms, you disrupt the airflow and cause your air conditioning system to work harder to distribute air to other areas of your home. Your system will work harder, to cool less space, making it cycle more and become less efficient.

Why are humidifiers used more in heating than cooling?

When cool outdoor air enters a home it tends to dry out as it warms up, which increases the static electricity in the home and causes sinus problems. Adding a humidifier with help to add moisture back into the air and limit sinus problems. In the summer, even with outdoor relative humidity hovering around the single digits, the humidity in your home tends to be around 40%. The average comfort range for relative humidity in a home is from 35 to 45%.

During the heating season, my heat pump delivers warm air, but not hot air, and will operate for long periods of time. Is that normal?

Yes, this is normal. A heat pump generally produces air that is 80°, which is considered warm, and will heat the house evenly. However, 80° may feel cool to your hand, which is usually closer to 90°.

During the heating season, my heat pump makes a whooshing sound and I feel cool air coming from the supply registers. Is that normal?

Yes. During the cold weather months, frost will accumulate on the outdoor coil. This will cause the heat pump to go into a defrost cycle anywhere from 1-10 minutes, depending on the amount of ice on the coil. The system will return to the heating mode once the ice is gone.

How do I know if my A/C unit is big enough?

Before purchasing a replacement system you should always make sure your system is sized properly. Our representative will provide a heat load calculation to determine the proper size and make the appropriate recommendation. Remember, bigger is not always better.

FAQ

General HVAC Questions

How often should I have my HVAC system serviced?

We recommend having your heating and cooling system professionally serviced twice a year, once in the spring before cooling season, and once in the fall before heating season. Regular maintenance helps catch small problems before they become expensive repairs, extends the life of your equipment, and keeps your system running at peak efficiency. Triad's Maintenance Plan members enjoy scheduled tune-ups, priority service, and savings on repairs.

How long does an HVAC system last?

Most well-maintained systems last 15–20 years. Air conditioners typically last 15–18 years, furnaces 18–20 years, and heat pumps 15–17 years. Systems in North Carolina that run heavily through hot summers may trend toward the lower end of those ranges. If your system is over 12 years old and needing frequent repairs, it may be more cost-effective to replace it than continue repairing it.

What brands of HVAC equipment does Triad Heating & Cooling install?

We are proud dealers of American Standard equipment and also service all major makes and models. We'll always recommend the right system for your home's size, layout, and budget not just the most expensive option.

Does Triad Heating & Cooling offer financing?

Yes. We offer financing options to help you manage the cost of a new system or major repair. We know HVAC work is a significant investment, and we want to make comfort accessible to every homeowner in the Triad area. Contact us or visit our financing page to learn more and apply.

Air Conditioning Questions

Why is my AC running but not cooling my house?

There are several common causes: a dirty air filter restricting airflow, low refrigerant levels, a frozen evaporator coil, a failing compressor, or a thermostat issue. Some of these are simple fixes, others require a professional diagnosis. If your AC is running constantly but your home isn't reaching the set temperature, call us for a service visit before the problem worsens.

How do I know if my air conditioner needs to be replaced or just repaired?

A good rule of thumb is the "$5,000 rule”, multiply the age of the system by the cost of the repair. If that number exceeds $5,000, replacement is usually the smarter investment. Other signs it's time to replace: your system is over 15 years old, it uses R-22 refrigerant (no longer manufactured), repairs have become frequent, or your energy bills keep climbing. Our technicians will give you an honest recommendation.

How much does a new air conditioner cost in North Carolina?

The cost varies based on the size of your home, the type of system, and the complexity of the installation. A standard central AC replacement in the Triad area typically ranges from $4,000 to $10,000 installed. We offer free estimates so you know exactly what to expect with no surprises.

What size air conditioner do I need for my home?

AC size is measured in tons and is determined by your home's square footage, insulation, ceiling height, sun exposure, and local climate, not a simple formula. An undersized unit won't cool effectively; an oversized one will cycle on and off too frequently and leave your home feeling humid. Our team performs a proper load calculation to match the right equipment to your home.

What is a ductless mini-split system and is it right for my home?

A ductless mini-split is a heating and cooling system that doesn't require ductwork. It's ideal for home additions, older homes without existing duct systems, sunrooms, garages, or any space that's difficult to condition with a traditional system. They're highly efficient and offer individual zone control. Triad installs and services ductless systems throughout our service area.

Heating & Furnace Questions

Why is my furnace blowing cold air?

Common causes include a tripped limit switch (usually from overheating), a dirty filter blocking airflow, a malfunctioning pilot light or ignitor, or a heat exchanger issue. If your furnace is running but your home isn't warming up, it's worth a call to our team. Some of these issues can be safety concerns if left unaddressed.

How do I know if my heat exchanger is cracked?

A cracked heat exchanger is a serious issue, it can allow carbon monoxide to enter your home's air supply. Warning signs include unusual smells when the furnace runs, soot buildup around the furnace, frequent headaches or dizziness in the home, or the furnace cycling on and off repeatedly. If you suspect a cracked heat exchanger, turn off the system and call us immediately.

What is a heat pump and how does it differ from a furnace?

A heat pump both heats and cools your home by moving heat rather than generating it. In winter, it extracts heat from outdoor air and moves it inside; in summer, it reverses and works like an air conditioner. Heat pumps are very efficient in mild-to-moderate climates like North Carolina. Furnaces generate heat by burning fuel or using electric resistance and are often paired with a heat pump for the coldest days (a "dual-fuel" system).

Is a gas furnace or heat pump better for homes in Greensboro and Asheboro, NC?

Both are excellent options in our area. North Carolina's climate is generally mild enough for a heat pump to handle heating efficiently most of the year. However, homes with natural gas access often benefit from a dual-fuel system, a heat pump for most of the year and a gas furnace as backup on the coldest days. Our team can help you weigh the costs and benefits for your specific home.

Indoor Air Quality & Duct Cleaning

How often should air ducts be cleaned?

The EPA suggests having your ductwork inspected and cleaned every 3–5 years, or sooner if you've had recent construction or renovation, notice visible mold or dust buildup at vents, have pets that shed heavily, or have family members with allergies or respiratory conditions. Because your ducts are hidden, they tend to get overlooked but they play a major role in your home's comfort and air quality.

Can dirty ducts affect my health?

Yes. Dust, pet dander, mold spores, and other contaminants can accumulate in your ductwork over time and circulate through your home every time your system runs. For households with allergy sufferers, asthma, or young children, professional duct cleaning can make a meaningful difference in the quality of the air you breathe indoors.

What is indoor air quality (IAQ) and what can I do to improve it?

Indoor air quality refers to how clean, fresh, and healthy the air inside your home is. Common issues include excess humidity, airborne allergens, dust, volatile organic compounds (VOCs), and inadequate ventilation. Triad offers a range of IAQ solutions including whole-home air purifiers, Aprilaire filtration systems, humidifiers and dehumidifiers, and UV air treatment systems.

Do I need a whole-home humidifier or dehumidifier?

North Carolina summers bring high humidity that can make your home feel warmer than it is, encourage mold growth, and damage wood floors and furniture. Winters bring dry air that can irritate skin and respiratory systems. A whole-home humidifier or dehumidifier integrated directly with your HVAC system gives you precise, automatic control over humidity levels year-round, which a portable unit simply can't match.

What is crawlspace encapsulation and why does it matter for my HVAC system?

Crawlspace encapsulation seals your crawlspace from moisture, pests, and outside air. Unencapsulated crawlspaces are a major source of humidity, mold, and energy loss in North Carolina homes, all of which put extra strain on your HVAC system. A properly encapsulated crawlspace helps your system run more efficiently and protects your home's structure and air quality.
