Question 1

How often should I have my AC serviced?

Accepted Answer

We recommend annual maintenance — ideally in spring before the cooling season. If you have a heat pump, schedule maintenance twice a year (spring and fall).

Question 2

Will maintenance really save me money?

Accepted Answer

Yes. A well-maintained system uses 15-25% less energy than a neglected one. It also reduces the risk of expensive breakdowns and extends the life of your equipment.

Question 3

What does a tune-up include?

Accepted Answer

Our 20-point inspection covers coil cleaning, refrigerant check, electrical testing, filter replacement, thermostat calibration, condensate drain clearing, and a full safety check.

Question 4

Why does my AC smell musty or moldy?

Accepted Answer

A musty smell means mold or mildew has grown somewhere in the system — usually on the evaporator coil, in the drain pan, or inside the ductwork. Asheville's high humidity makes this especially common. We clean the coil, treat the drain pan, and can recommend UV germicidal lights that kill mold and bacteria continuously inside the system.

Question 5

How often should I change my AC filter?

Accepted Answer

Standard 1-inch filters should be replaced every 30-60 days during heavy use and every 90 days minimum. If you have pets, allergies, or a dusty home, lean toward monthly changes. Pleated 4-inch media filters last 6-12 months. A clogged filter is the number one preventable cause of AC breakdowns, frozen coils, and high energy bills.

Question 6

Should I upgrade to a smart thermostat?

Accepted Answer

A smart thermostat like an Ecobee or Honeywell T-series can reduce energy costs by 10-15% through learning your schedule and adjusting automatically. They also provide remote access so you can monitor your system from anywhere. We install and configure smart thermostats and make sure they're wired and set up correctly for your specific system type — not all thermostats are compatible with all systems.

Question 7

How long does a central air conditioner last?

Accepted Answer

A well-maintained central AC in Western North Carolina typically lasts 15-20 years. Systems in our area may last on the shorter end of that range because of our hot, humid summers and the altitude-related UV exposure on outdoor units. Regular maintenance — annual tune-ups, clean filters, and keeping the outdoor unit clear — is the biggest factor in reaching the upper end of that lifespan.

Question 8

How much does an AC tune-up cost?

Accepted Answer

Our comprehensive AC tune-up runs between $89 and $149 depending on the system type. Maintenance plan members receive discounted tune-up pricing along with priority scheduling and reduced diagnostic fees year-round. Considering that a tune-up can prevent a $500+ repair and reduces energy consumption by 15-25%, it's one of the best values in home maintenance.

Question 9

What does an AC tune-up include?

Accepted Answer

Our 20-point AC tune-up includes cleaning the condenser coil, checking refrigerant charge, tightening electrical connections, testing capacitors, lubricating motors, inspecting the evaporator coil, clearing the condensate drain, replacing the air filter, calibrating the thermostat, and performing a complete system performance test. We also check for safety issues and anything that could lead to a future breakdown.

Question 10

When should I schedule my AC maintenance in Asheville?

Accepted Answer

Schedule your AC tune-up in March or April — before the summer cooling season begins and before our schedule fills up. Early-season maintenance ensures your system is running at peak efficiency when you need it most, and gives us time to address any issues before the first heat wave hits. Fall is the time to service your heating system.

Question 11

Can I do my own AC maintenance?

Accepted Answer

You can handle the basics — changing filters monthly, keeping the outdoor unit clear of debris and vegetation (maintain 2 feet of clearance), and rinsing the condenser coils with a garden hose. However, checking refrigerant levels, testing electrical components, inspecting the evaporator coil, and verifying system performance require professional tools and training. DIY work beyond the basics can void warranties and cause damage.

Question 12

How often should I replace my AC filter?

Accepted Answer

Standard 1-inch disposable filters should be replaced every 30-90 days, with monthly changes recommended during peak summer use. Homes with pets, smokers, or allergy sufferers should change on the shorter end. Thicker 4-inch or 5-inch media filters last 6-12 months. Holding a filter up to light is a quick test — if you can't see light through it, it's time to replace it.

Question 13

How can I lower my AC electricity costs?

Accepted Answer

The biggest impacts come from regular maintenance (saves 15-25% on cooling costs), sealing duct leaks (most homes lose 20-30% of conditioned air through leaky ducts), upgrading to a programmable or smart thermostat, and setting your thermostat to 78°F when home and higher when away. Also make sure your filter is clean, your outdoor unit has airflow clearance, and your attic insulation meets current standards.

Question 14

What temperature should I set my AC to in summer?

Accepted Answer

The Department of Energy recommends 78°F when you're home, 85°F when you're away, and 82°F while sleeping. Every degree below 78°F increases your cooling costs by about 3-5%. In Asheville's climate, most of our customers find 74-76°F comfortable. A programmable thermostat makes it easy to automatically adjust temperatures based on your schedule.

Question 15

Do you work on all AC brands?

Accepted Answer

Yes. Our NATE-certified technicians are trained and experienced on all major brands including Trane, Carrier, Lennox, Rheem, Goodman, American Standard, York, Amana, Daikin, Mitsubishi, and more. We stock common parts for all brands on our trucks to complete most repairs in a single visit regardless of what brand you have.

Question 16

How do I prepare my AC for winter?

Accepted Answer

At the end of cooling season, run the system on fan-only for a few hours to dry the evaporator coil, then turn the system off at the thermostat. Outside, remove any debris from the condenser, trim vegetation back to 2 feet of clearance, and consider covering the top of the unit with a piece of plywood (not a full cover, which traps moisture and invites rodents). Do not wrap the entire outdoor unit — moisture needs to escape.

Question 17

What should I do before turning on my AC for the first time in spring?

Accepted Answer

Before the first spring start-up, replace the air filter, clear debris from around the outdoor unit, visually inspect the refrigerant lines for damage, and make sure all supply and return vents inside are open and unobstructed. Turn the system on and let it run for 15-20 minutes, then check that cool air is coming from all vents. Better yet, schedule a professional spring tune-up to catch any issues before the summer heat arrives.

Question 18

Should I cover my outdoor AC unit in winter?

Accepted Answer

A full cover is not recommended — it traps moisture and creates a warm shelter for rodents who may chew wiring. A simple piece of plywood placed on top of the unit and weighted down is sufficient to protect it from falling ice and debris. The outdoor unit is engineered to withstand the elements. Focus instead on clearing leaves and debris and maintaining 2 feet of clearance around it.

Question 19

Is it bad to turn my AC on and off frequently?

Accepted Answer

Yes. Frequent manual cycling stresses the compressor because it needs several minutes of off-time between cycles to equalize internal pressures. Use a programmable thermostat to manage temperature setbacks instead of turning the system on and off. Setting the temperature higher when you leave (not turning it off completely) is better for both your comfort when you return and the longevity of your equipment.

Question 20

How often should I get an HVAC tune-up?

Accepted Answer

We recommend twice a year — once in spring to prep your AC for summer and once in fall to prep your heating system for winter. A system that gets regular maintenance runs more efficiently, breaks down less often, and lasts 5–7 years longer than a neglected one. Most manufacturer warranties also require annual professional maintenance to stay valid.

Question 21

What's included in an HVAC tune-up?

Accepted Answer

Our tune-ups include checking and tightening electrical connections, cleaning the condensate drain, checking refrigerant charge and pressures, inspecting the heat exchanger or coils, testing safety controls, lubricating moving parts, checking thermostat calibration, and measuring airflow and temperature differential. We also check your filter and let you know if your ductwork has any obvious issues.

Question 22

Can I do my own HVAC maintenance?

Accepted Answer

You can handle the basics: change your filter every 1–3 months, keep the outdoor unit clear of debris and vegetation (2 feet of clearance all around), make sure your condensate drain isn't clogged, and keep supply and return vents unblocked. But the technical stuff — checking refrigerant charge, testing electrical components, inspecting the heat exchanger, and cleaning the evaporator coil — requires professional tools and training.

Question 23

What type of air filter should I use for my HVAC system?

Accepted Answer

For most residential systems, we recommend a MERV 8–11 pleated filter — it catches dust, pollen, and pet dander without restricting airflow too much. MERV 13+ filters are great for air quality but can reduce airflow in systems not designed for them, causing the evaporator coil to freeze. If you want higher filtration, talk to us about whether your system can handle it or if a whole-house air purifier is a better fit.

Question 24

How often should I change my HVAC air filter?

Accepted Answer

Standard 1-inch filters should be changed every 30–90 days depending on your household — homes with pets, allergies, or heavy dust need monthly changes. If you have a 4-inch or 5-inch media filter, those typically last 6–12 months. A clogged filter is the number one cause of preventable HVAC breakdowns — it restricts airflow, causes the system to overheat or freeze, and runs up your energy bill.

Question 25

What do MERV ratings mean for air filters?

Accepted Answer

MERV (Minimum Efficiency Reporting Value) measures how well a filter captures particles. MERV 1–4 catches only large debris. MERV 8 catches dust, pollen, and mold spores. MERV 11 adds pet dander and smog. MERV 13+ catches bacteria and some viruses but requires a system designed for the extra resistance. Higher isn't always better — if the filter is too restrictive for your system, it causes more harm than good.

Question 26

What should I do to prepare my AC for summer?

Accepted Answer

In spring, schedule a professional tune-up, change your filter, clear debris from around the outdoor unit, clean the condensate drain line with a cup of vinegar, and test the system in cooling mode before the first hot day. Here in Western NC, late March or April is the best time — if you wait until June and something's wrong, you'll be competing with everyone else for service appointments.

Question 27

Are HVAC maintenance plans worth the money?

Accepted Answer

For most homeowners, yes. Our maintenance plans include two annual tune-ups, priority scheduling, a discount on repairs, and no overtime charges — typically saving $200–400/year compared to paying for everything individually. More importantly, regular maintenance catches small problems before they become expensive failures. We've seen countless systems in the Asheville area that could have avoided a $1,500 repair with a $150 tune-up.

Question 28

How often should evaporator and condenser coils be cleaned?

Accepted Answer

The condenser coil (outdoor unit) should be cleaned annually — cottonwood fluff, grass clippings, and pollen coat the fins and block airflow. The evaporator coil (indoor unit) should be inspected annually and cleaned as needed, typically every 2–3 years. Dirty coils reduce system capacity by up to 30% and are a leading cause of compressor failure. Both coils are included in our maintenance tune-ups.

Question 29

Why is my HVAC system not as efficient as it used to be?

Accepted Answer

Efficiency naturally declines with age — a system loses about 5% of its efficiency for every year of missed maintenance. Common efficiency killers include dirty coils, clogged filters, refrigerant leaks, worn blower motors, and duct leaks that have developed over time. If your system is over 10 years old and energy bills are climbing, a maintenance visit can often recover some of that lost efficiency, but at some point replacement becomes the better investment.

Question 30

What happens if I skip HVAC maintenance for a few years?

Accepted Answer

Skipping maintenance leads to a cascade of problems: the filter clogs, airflow drops, the coil gets dirty, the system works harder, components wear out faster, and efficiency plummets. We regularly see systems that could have lasted 18–20 years fail at 10–12 years because they were never serviced. The repair that finally prompts the call is often a compressor or heat exchanger failure — the two most expensive components in your system.

Question 31

Can my HVAC system help with allergies?

Accepted Answer

Absolutely — your HVAC system filters all the air in your home multiple times a day. Upgrading to a MERV 11–13 filter, adding a whole-house air purifier, sealing duct leaks that pull in unfiltered air, and keeping the system well-maintained can dramatically reduce allergens like pollen, dust mites, pet dander, and mold spores. Many of our customers in the Asheville area notice a significant improvement in allergy symptoms after upgrading their filtration.

Question 32

How does mold get into HVAC systems?

Accepted Answer

Mold thrives in dark, damp environments — and your evaporator coil, drain pan, and ductwork provide exactly that. When condensation sits on a dirty coil or in a clogged drain pan, mold colonies form and then get distributed through your home every time the blower runs. Leaky ductwork in humid crawlspaces is another major mold entry point. Regular maintenance, UV lights, and proper drainage are the best defenses.

Question 33

How can I reduce dust in my home through my HVAC system?

Accepted Answer

Start with a good-quality pleated filter (MERV 8–11) and change it regularly. Seal duct leaks — especially at connections and in the crawlspace — because every gap sucks in unfiltered dusty air. Make sure your return vents aren't blocked by furniture. Running the fan on 'ON' for short periods can help circulate and filter air, but a whole-house air purifier is the most effective upgrade if dust is a persistent issue in your home.
