Question 1

Why isn't my AC cooling?

Accepted Answer

The most common causes are a dirty air filter, poor airflow, a failing capacitor, low refrigerant from a leak, dirty outdoor coils, or a thermostat issue. Start by checking the thermostat setting and replacing the filter. If the system still runs without cooling well, schedule professional AC repair so the issue can be diagnosed before it turns into compressor damage.

Question 2

Why is my AC running but not cooling the house?

Accepted Answer

If the AC is running but the home is not cooling, the system may have restricted airflow, dirty coils, a refrigerant issue, duct leakage, or an outdoor unit problem. If the filter is clean and the thermostat is set correctly, it is time to schedule service.

Question 3

Why is my AC freezing up?

Accepted Answer

Ice on an AC system usually points to restricted airflow, a dirty filter, dirty evaporator coil, blocked return air, or low refrigerant. Turn the system off and let it thaw before running it again. If ice returns, the system needs service. An AC inspection can help find the cause.

Question 4

Why is my AC leaking water?

Accepted Answer

Water around the indoor unit may come from a clogged condensate drain line, frozen coil, cracked drain pan, or improper drainage. If the system is actively leaking, shut it off and schedule service to protect ceilings, flooring, and nearby equipment.

Question 5

How long does an air conditioner last?

Accepted Answer

A well-maintained air conditioner often lasts around 10 to 15 years. If your AC needs frequent repairs, struggles to cool the home, uses more energy than it used to, or still uses older refrigerant, it may be time to compare repair costs with AC installation.

Question 6

What is AC rejuvenation?

Accepted Answer

AC rejuvenation is a more performance-focused service designed to help improve cooling, airflow, reliability, and efficiency where possible. It is useful when a system feels tired, has not been serviced recently, or is cooling less effectively than it used to. Learn more about AC rejuvenation.

Question 7

Should I repair or replace my AC?

Repair may make sense for a newer system with a minor issue. Replacement may be smarter if the AC is older, inefficient, uses frequent repairs, or has a major failure. A technician can compare repair cost, equipment age, comfort problems, and energy use to help you make a practical decision.

Question 8

Why is my furnace blowing cold air?

Accepted Answer

First, check whether the thermostat fan is set to “ON” instead of “AUTO.” If the fan setting is correct, the furnace may have an ignition problem, dirty flame sensor, tripped safety limit, gas supply issue, or another problem requiring furnace repair.

Question 9

Why does my furnace keep turning on and off?

Accepted Answer

Short cycling can be caused by a dirty filter, restricted airflow, an overheating furnace, thermostat placement, blocked vents, or an oversized system. Because short cycling adds wear to the equipment, it is worth having the system checked before the problem gets worse.

Question 10

How long does a furnace last?

Accepted Answer

Many gas furnaces last around 15 to 20 years with proper maintenance. Rising bills, uneven heat, loud operation, safety concerns, or frequent repairs can be signs it is time to consider furnace installation.

Question 11

What is furnace rejuvenation?

Accepted Answer

Furnace rejuvenation is a deeper performance service designed to help restore airflow, comfort, reliability, and heating performance where possible. It is not magic and it will not make an old furnace brand new, but it can help a tired system heat better and reveal issues before they become bigger repairs.

Question 12

Is furnace rejuvenation the same as furnace maintenance?

Accepted Answer

They are related, but not always the same. Standard maintenance is usually a seasonal checkup. Furnace rejuvenation is positioned as a more detailed performance-focused service for systems that need extra attention, improved airflow, cleaning, and comfort recommendations.

Question 13

Why does my furnace smell when I first turn it on?

Accepted Answer

A light dusty smell at the first startup of the season can be normal as dust burns off. Strong burning smells, gas odors, electrical smells, smoke, or persistent odors are not normal. Shut the system off and call for service if the smell seems unsafe or does not go away quickly.

Question 14

What does a furnace inspection include?

Accepted Answer

A furnace inspection typically checks system operation, burners, ignition, safety controls, airflow, thermostat response, filter condition, electrical components, and visible wear. It helps catch problems before cold weather pushes the system harder.

Question 15

What is the difference between a heat pump and an air conditioner?

Accepted Answer

An air conditioner only cools. A heat pump can cool in summer and provide heat in colder months by moving heat rather than creating it like a furnace. Heat pumps can be a strong comfort option when they are properly sized and installed for the home.

Question 16

Why is my heat pump blowing cool air in winter?

Accepted Answer

Heat pump air can feel cooler than furnace air even when the system is working correctly. But if the home is not warming up, the outdoor unit is frozen, auxiliary heat is not working, or the system runs nonstop, schedule heat pump repair.

Question 17

Why does my heat pump freeze up?

Accepted Answer

A light frost can be normal, and heat pumps use a defrost cycle to clear it. Heavy ice buildup may point to airflow issues, low refrigerant, a defrost control problem, dirty coils, or outdoor unit issues.

Question 18

How often should a heat pump be inspected?

Accepted Answer

Because heat pumps can run for both heating and cooling, they should usually be checked at least once a year, and often twice a year for heavy-use systems. A heat pump inspection helps confirm performance before peak weather.

Question 19

When should I replace my heat pump?

Accepted Answer

Replacement may make sense if the heat pump is older, inefficient, noisy, frequently breaking down, struggling in both seasons, or facing a major repair. Compare the repair cost against the comfort and efficiency benefits of heat pump installation.

Question 20

What is a ductless mini-split?

Accepted Answer

A ductless mini-split is a heating and cooling system that uses an outdoor unit connected to one or more indoor units. It can provide targeted comfort without traditional ductwork, making it useful for additions, garages, basements, offices, sunrooms, and rooms that are hard to heat or cool.

Question 21

Can a mini-split heat and cool?

Yes. Many mini-splits are ductless heat pumps, which means they can cool in summer and provide heat during colder weather. Performance depends on system design, sizing, placement, and outdoor conditions.

Question 22

Where are mini-splits a good fit?

Accepted Answer

Mini-splits are often a good fit for room additions, finished basements, garages, workshops, home offices, older homes without ducts, upstairs comfort problems, and spaces where extending ductwork would be difficult or expensive.

Question 23

Why is my mini-split leaking water?

Accepted Answer

A leaking mini-split may have a clogged drain line, dirty filter, frozen coil, improper slope, or drainage issue. Turn the system off if water is damaging the wall or floor and schedule mini-split repair.

Question 24

Why is my mini-split not cooling?

Accepted Answer

A mini-split that is not cooling may have a dirty filter, blocked indoor coil, outdoor unit issue, refrigerant problem, sensor issue, or control problem. If cleaning the filter does not help, schedule service before the system is strained further.

Question 25

How often should mini-splits be inspected?

Accepted Answer

Mini-splits should be inspected regularly, especially before heavy heating or cooling seasons. A mini-split inspection can check airflow, drainage, electrical controls, temperature performance, noise, and overall operation.

Question 26

What is the difference between single-zone and multi-zone mini-splits?

Accepted Answer

A single-zone mini-split serves one area with one indoor unit. A multi-zone system connects multiple indoor units to one outdoor unit so different rooms can have their own comfort control. A proper mini-split installation plan should consider layout, sizing, room usage, and comfort goals.

Question 27

What does a whole-home air purifier do?

Accepted Answer

A whole-home air purifier works with your HVAC system to help reduce airborne particles throughout the home. Depending on the system, it may help reduce dust, odors, pet dander, smoke particles, and other indoor air quality concerns. It should be professionally matched to your equipment.

Question 28
