Question 1

Why Is My AC Not Cooling?

Accepted Answer

Check your air filter first — a clogged filter is the #1 reason your AC runs but doesn't cool. If the filter is clean, check if the outdoor unit is running, look for ice on the indoor coil, and make sure the thermostat is set correctly. If none of those fix it, you likely need a technician for a refrigerant or compressor issue.

Question 2

How Often Should I Change My AC Filter?

Accepted Answer

Every 30-90 days depending on your filter type, home size, and whether you have pets. In hot climates like Florida where your AC runs 8+ months a year, change it monthly during summer. A 1-inch filter needs changing more often than a 4-inch media filter. When in doubt, pull it out and look — if you can't see light through it, it's done.

Question 3

Why Is My AC Leaking Water Inside?

Accepted Answer

A clogged condensate drain line is the most common cause — especially in humid climates where algae builds up fast. Turn off your AC immediately to prevent water damage, then check the drain line. You can usually clear it with a wet/dry vac or vinegar flush. If the drain line is clear, you may have a frozen evaporator coil or a cracked drain pan.

Question 4

How Long Do HVAC Systems Last?

Accepted Answer

A central AC or heat pump typically lasts 12-17 years, with 15 being the average in moderate climates. In hot, humid climates like Florida where systems run 8-10 months a year, expect closer to 10-14 years. Proper maintenance — annual tune-ups, regular filter changes, clean coils — can add 3-5 years to your system's life.

Question 5

Why Does My AC Smell Bad?

Accepted Answer

A musty or moldy smell means moisture is growing mold or mildew inside your air handler, on the evaporator coil, or in your ductwork. This is extremely common in humid climates. A dirty sock smell points to bacteria on the coil. A burning smell means turn the system off immediately — it could be an electrical issue. All are fixable, but the cause determines whether it's DIY or needs a pro.

Question 6

What SEER Rating Should I Get?

Accepted Answer

For most homeowners, a 15-17 SEER2 unit hits the sweet spot between efficiency and cost. Going above 18 SEER2 has diminishing returns — the equipment cost jumps significantly while the energy savings get smaller. The minimum in the Southeast US is now 15 SEER2. Focus less on chasing the highest number and more on proper sizing and installation, which affect efficiency more than the rating itself.

Question 7

How to Fix a Running Toilet?

Accepted Answer

A running toilet is almost always one of three cheap parts: the flapper (most common — a $5 rubber seal at the bottom of the tank), the fill valve (the tall mechanism that refills the tank), or the float being set too high. Open the tank lid, flush, and watch what happens. If water leaks past the flapper, replace it. If the fill valve won't shut off, replace or adjust it. Each fix is under $15 and takes 15 minutes.

Question 8

How to Fix a Leaky Faucet?

Accepted Answer

Turn off the water supply under the sink first. Most leaky faucets need either a new cartridge (single-handle) or new seats and springs (two-handle). Remove the handle, pull the cartridge or valve stem, and take it to the hardware store to match the replacement. The part is usually $8-20 and the repair takes 20-30 minutes. A faucet dripping once per second wastes over 3,000 gallons per year.

Question 9

How Long Do Water Heaters Last?

Accepted Answer

A standard tank water heater lasts 8-12 years, with 10 being typical. In areas with hard water (like Northwest Florida), expect closer to 6-9 years without proper maintenance. Tankless units last 15-20 years. The best way to extend your water heater's life is flushing the tank annually and replacing the anode rod every 3-5 years — two cheap maintenance tasks most homeowners skip.

Question 10

Why Is My Water Heater Not Working?

Accepted Answer

No hot water at all usually means a tripped breaker (electric) or a pilot light that's gone out (gas). Check those first — they're the two easiest fixes. If hot water runs out fast, sediment buildup or a failing heating element is likely. If water is lukewarm, the thermostat may need adjusting (should be 120°F). If you hear popping or rumbling, sediment has hardened on the bottom — flush the tank or start planning a replacement.

Question 11

How to Unclog a Drain?

Accepted Answer

Start simple: remove the stopper and clear any visible hair or debris. Then try a plunger (use a flat plunger for sinks, a flange plunger for toilets — most people use the wrong one). If that doesn't work, a $25 drain snake will clear most clogs within 3 feet of the drain. Skip the chemical drain cleaners — they damage pipes and rarely fix the real problem. If multiple drains are slow, the issue is in your main line and you need a plumber.

Question 12

Why Is My Water Pressure Low?

Accepted Answer

Low pressure at one faucet is usually a clogged aerator — unscrew the tip of the faucet, clean the screen, and reinstall. Takes 2 minutes. Low pressure throughout the house means something bigger: a partially closed main shutoff valve (check the valve at the meter and at the house), a failing pressure reducing valve, or a municipal supply issue. If pressure dropped suddenly after plumbing work, someone may have left a valve partially closed.

Question 13

Why Does My Circuit Breaker Keep Tripping?

Accepted Answer

A breaker that trips once is protecting you from a temporary overload — too many devices on one circuit. Unplug some things and reset it. A breaker that trips repeatedly means either a persistent overload (move high-draw appliances to different circuits), a short circuit in the wiring, or a failing breaker. If it trips immediately every time you reset it, stop resetting it — that's likely a wiring issue and you need an electrician. Breakers wear out after 20-30 years.

Question 14

How to Test a GFCI Outlet?

Accepted Answer

Press the TEST button on the outlet — it should click and kill power to that outlet (and any outlets downstream from it). Then press RESET to restore power. Do this monthly. If pressing TEST doesn't trip it, or if RESET won't hold, the GFCI is bad and needs replacing. One GFCI outlet can protect multiple regular outlets on the same circuit, so a dead outlet in your garage might be controlled by a GFCI in your bathroom.

Question 15

How Often Should I Replace Smoke Detectors?

Accepted Answer

Replace the entire unit every 10 years — there's a manufacture date on the back. Replace batteries yearly (or when it chirps). Test monthly by pressing the test button. You need one on every floor, one inside each bedroom, and one outside each sleeping area. A chirping smoke detector usually means low battery, but if it chirps with a new battery, the unit itself has reached end of life.

Question 16

Why Is My Dishwasher Not Cleaning Well?

Accepted Answer

Clean the filter first — most people don't know their dishwasher has one, and a clogged filter is the #1 cause of poor cleaning. It's usually at the bottom of the tub, twists out, and takes 2 minutes to rinse clean. Next, check the spray arms for clogged nozzles (use a toothpick). Make sure your water is hot enough — run the kitchen faucet until it's hot before starting a cycle. If you're using pods, make sure they're going in the dispenser, not the bottom of the tub.

Question 17

Why Does My Dryer Take So Long to Dry?

Accepted Answer

A clogged dryer vent is the cause 90% of the time — and it's also a fire hazard (2,900 dryer fires per year in the US). Clean the lint screen every load and clean the full exhaust vent from the dryer to the outside wall at least once a year. If clothes are still damp after a normal cycle, pull the dryer out and check for a crushed or kinked vent hose. If the vent is clear, the heating element or moisture sensor may be failing.

Question 18

How Much Does It Cost to Replace an AC Unit?

Accepted Answer

A full central AC replacement (equipment + installation) runs $4,500-$12,000 depending on system size, efficiency rating, and your region. In the Southeast US, most 3-ton residential replacements land between $5,500-$8,500 for a standard efficiency unit. High-efficiency (17+ SEER2) or heat pump systems cost more upfront but reduce energy bills. Always get 3 quotes, and be skeptical of quotes that are dramatically lower — the installation quality matters more than the equipment brand.

Question 19

How Much Does a New Water Heater Cost?

Accepted Answer

A standard 50-gallon tank water heater costs $1,200-$2,500 installed (equipment + labor). Tankless units run $2,500-$5,000 installed. Heat pump water heaters are $2,000-$4,000 installed but qualify for federal tax credits up to $2,000 and use 60-70% less energy. The installation cost varies a lot by region and whether your existing plumbing/electrical needs modifications. Budget $1,500-$2,000 for a straightforward tank replacement in most markets.

Question 20

What Home Maintenance Should I Do Monthly and Annually?

Accepted Answer

Monthly: replace HVAC filter, test GFCI outlets, check under sinks for leaks, test smoke detectors, run garbage disposal. Seasonally: flush water heater (fall), clean AC condenser (spring), clean gutters (spring and fall), flush condensate drain line (summer). Annually: professional HVAC tune-up, full plumbing inspection, check water heater anode rod, test water pressure, inspect roof from ground, clean dryer vent. Budget 1-2% of your home's value per year for maintenance.
