Question 1

Why Is My AC Running But Not Cooling The House?

Accepted Answer

An AC that runs but is not cooling usually points to airflow, thermostat/control, drain, coil, electrical, or refrigerant issues. The most common cause is restricted airflow from a dirty filter or dirty coils that block heat transfer. Other times, a mis-set thermostat, a clogged condensate drain, or an electrical component fault keeps the system from actually cooling. A unit that short-cycles often leads us to check controls and sensors before we test refrigerant levels. We resolve this problem often for homeowners in the Morgantown area. Our technicians arrive in fully stocked trucks, so most repairs can be completed on the same visit. If you see ice on the lines or water around the indoor unit, turn the system off to thaw and schedule a diagnostic.

Try these quick checks before service:
- Set the thermostat to Cool and at least 5°F below room temperature; fan on Auto.
- Replace a dirty filter and make sure all supply and return vents are open.
- Clear debris around the outdoor unit and note any rapid starts/stops.
- Look for water at the air handler or ice on the refrigerant lines.

Question 2

How Do I Reset My Air Conditioner Safely?

Accepted Answer

Reset an air conditioner safely by fully powering it down, letting the controls discharge, then restoring power and restarting cooling. Most homeowners do this after a power flicker or nuisance trip to clear a minor control fault. A clean five‑minute power-down lets compressor pressure equalize so it can start smoothly. If your system immediately trips again or won’t start, stop and schedule service to prevent equipment damage. Our technicians handle safe resets and diagnostics throughout Central Indiana, including homes near Boggstown. - Turn the thermostat to Off (include fan Auto). - Switch the indoor furnace/air handler power switch Off and flip the AC breaker Off; pull the outdoor disconnect if present. - Wait 5–10 minutes with everything Off. - Restore power at the disconnect and breaker, turn the indoor switch On, then set thermostat to Cool and a lower temperature. If you smell burning, see ice on lines, or the breaker trips again, do not retry the reset and call a licensed technician.

Question 3

Why Is My HVAC Turning On But Not Heating The House?

Accepted Answer

An HVAC system that turns on but doesn’t heat usually means the thermostat or airflow is wrong, or the burner/ignition safety isn’t allowing a heat cycle. Most often the thermostat is set to Cool or Fan, or a clogged filter has choked airflow so the system can’t heat the house. If a furnace blower runs but the burners never light, the flame sensor or igniter may be the culprit; with heat pumps, lukewarm air can point to defrost or low refrigerant. This is common and often simple to correct, but repeated lockouts suggest a failing component and deserve a technician’s diagnosis. We handle calls throughout the New Palestine area and see this most after long filter intervals or thermostat reprogramming. Our certified techs arrive in fully stocked trucks, so most repairs can be completed on the same visit. Call now if you notice any of these: * Gas smell near the furnace * Ice buildup on the outdoor unit * Fast clicking or repeated restarting * Water pooling around the air handler Before you call, set the thermostat to Heat, replace the filter, and check the breaker; if it still blows cool air, turn the system off and schedule a diagnostic.

Question 5

What is the average cost to fix a furnace?

Accepted Answer

The average cost to fix a furnace is not a single set price; Johnson Heating, Cooling, and Plumbing provides upfront pricing after an on-site diagnosis because costs vary by the failed part, labor time, and system condition. Many no-heat calls trace to wear items or sensor issues, while larger components change the scope and cost. A quick ignitor swap and a seized blower can look identical at the thermostat but not on the invoice. You’ll get honest, upfront pricing with no surprise fees, and completed repairs are backed by our Fixed Right or It’s Free guarantee for six months. We serve the Needham area with fully stocked trucks, so many repairs are completed in one visit. Key factors that influence your total: * Part type and availability * System age and maintenance history * Existing part warranties * Equipment access and any safety/code corrections If you smell gas or a carbon monoxide alarm sounds, exit and call emergency services before scheduling repair.

Question 7

How Much Does Residential HVAC Maintenance Cost Annually?

Accepted Answer

Residential HVAC maintenance with Johnson Heating, Cooling, and Plumbing costs $19.95 per month through our Comfort Club, which is about $240 per year. Most homeowners choose this plan to cover seasonal tune-ups and receive 15% off repairs. Total annual spend can change based on your home and equipment, and any one-time tune-up outside the plan is priced at scheduling. Our team maintains systems across Central Indiana, including the Shelbyville area. A well-run tune-up often spots small airflow or drainage issues long before they become expensive failures. If your system is older or has frequent issues, a plan usually saves money; if it’s newer and under warranty, a basic check may be enough. Book maintenance before the first big heat or cold snap to avoid peak-season delays. * Factors that can raise or lower yearly cost: * Number of HVAC systems in the home * Age/condition and past maintenance history * Add-ons like air purifiers, humidifiers, or advanced filters * Urgent service needs discovered during checks

Question 8

How Can I Fix My HVAC When It Is Not Blowing Hot Air?

Accepted Answer

To fix an HVAC system that isn’t blowing hot air, start with basic checks: confirm the thermostat is set to Heat and a higher temperature, the air filter is clean, and power to the furnace or air handler is on. The most common cause is an incorrect thermostat mode or a clogged filter that restricts airflow and can shut equipment down. If the blower runs but air stays cool, ignition or safety sensors may be keeping the burner off; our technicians often find a dirty flame sensor after long gaps between tune-ups. We handle this problem routinely for families throughout Central Indiana, including homes near Zionsville. Our certified technicians arrive in fully stocked trucks, so most repairs can be completed on the same visit, with honest, upfront pricing with no surprise fees. Try these simple steps before calling: * Set thermostat to Heat and fan to Auto; replace batteries if needed. * Replace a dirty filter; make sure vents and returns are open. * Check the furnace switch and breaker; verify the gas valve is on. * For heat pumps, clear snow/debris from the outdoor unit. If you smell gas, turn the system off and call a licensed pro immediately.

Question 9

How Can I Reset My Air Conditioner to Fix Power Issues?

Accepted Answer

Resetting an air conditioner to fix power issues means safely shutting off power to the system, waiting five minutes, then restoring power in the right order. Most power problems follow an outage or surge that trips a breaker or puts the compressor into a protective timeout. Give the system a true five‑minute “compressor timeout”; cutting it short can keep the unit locked out. Our certified technicians arrive in fully stocked trucks, so most repairs can be completed on the same visit. We handle many post‑storm resets across the Columbus area and can test for loose connections or weak capacitors if it trips again. Try this simple reset procedure: * Set the thermostat to Off. * Turn the AC/HVAC breakers Off (and pull the outdoor disconnect if present); wait 5 minutes. * Turn breakers and disconnect On, then set Cool, Auto fan, and lower the setpoint. * Stop and call a pro if the breaker trips again, you smell burning, or hear loud buzzing. If the breaker keeps tripping or you hear humming without the fan, stop trying to reset and schedule service to prevent equipment damage.

Question 10

Why Is My Air Conditioner Not Turning On Despite Thermostat Set to Cool?

Accepted Answer

An air conditioner that won’t turn on with the thermostat set to Cool usually indicates a power, control, or safety lockout problem. The most common culprits are incorrect thermostat settings or dead thermostat batteries, followed by a tripped breaker or a condensate safety switch that shut the system down to prevent water damage. If the unit was just powered off, many systems impose a 3–5 minute restart delay to protect the compressor. Around our Trafalgar service calls, we often find a small algae plug in the drain pan float switch that silently stops the system. Try these quick checks before calling: * Set thermostat to Cool, Fan Auto, and drop the setpoint at least 5°F below room temp. * Replace thermostat batteries and confirm the date/time isn’t in a schedule Hold. * Check the furnace/air handler switch, outdoor disconnect, and the AC breaker; reset once only. * Inspect the air filter; a severely clogged filter can trigger safety limits. * Look for water in the indoor unit pan; a tripped float switch means the drain is clogged. If a breaker trips again after one reset, leave it off and book service to avoid equipment or wiring damage.

Accepted Answer

If your HVAC system needs emergency repair now, turn the system off and call Johnson Heating, Cooling, and Plumbing for rapid diagnostics and same-visit repairs.

Question 12

Why Is My HVAC Not Heating Even Though It Turns On?

Accepted Answer

An HVAC system that turns on but does not heat usually points to an airflow restriction, thermostat/control error, or a fuel/electrical safety lockout. Most often the problem starts with a simple setting or blocked airflow that causes the furnace or heat pump to shut the heat off for protection. Technician note: a stuck heat-pump reversing valve can make vents feel cool even while the system runs. Around Franklin, our certified technicians arrive in fully stocked trucks to finish most repairs in one visit. Before you call, check these quick items: * Set the thermostat to Heat and raise the setpoint above room temperature. * Replace a dirty air filter and ensure vents are open. * Verify the furnace switch and breaker are on; reset once if tripped. * For gas heat, confirm the gas valve is open; for heat pumps, clear heavy ice from the outdoor unit. If you smell gas, see repeated breaker trips, or the unit short-cycles, turn it off and schedule a professional inspection.

Question 13

What Is the Average Furnace Repair Cost for Homeowners?

Accepted Answer

The average furnace repair cost for homeowners varies by issue and is confirmed after an on‑site diagnostic; there isn’t a single “standard” price. Most costs stem from the specific part that failed and the labor time to test, access, and replace it. Many no‑heat calls trace to a dirty flame sensor or a failed igniter found with a quick meter check, while control boards and blower motors tend to be higher‑complexity fixes. We handle these diagnostics and repairs throughout the Lebanon area with honest, upfront pricing with no surprise fees. What drives repair price: * Part and labor: igniters, flame sensors, blower motors, or control boards need different parts and time * System age and warranty coverage for parts * Access limits, venting, or code updates that add labor * After‑hours or emergency timing If you smell gas, turn off the furnace and gas supply and contact a licensed technician immediately.

Question 14

How much does same day HVAC repair typically cost?

Accepted Answer

Same day HVAC repair pricing is confirmed after an on-site diagnostic because the cost depends on the exact failure and parts needed. The biggest driver is which component failed and how much labor is required to restore safe operation. A technician insight: simple electrical parts can be quick; motor failures or refrigerant issues take more time because testing and setup matter. Our team serving the Mooresville area provides honest, upfront pricing with no surprise fees, and our certified technicians arrive in fully stocked trucks so most repairs can be completed on the same visit. Expect the diagnostic to determine these price factors: * Part type and availability (sensor, capacitor, motor, control board) * System type and size (AC, furnace, heat pump) * Refrigerant or combustion work requirements * Accessibility and after-hours timing * Any existing warranties on parts or labor Optional savings: $50 off AC system repair (cannot be combined or applied to the diagnostic; expires May 2026). Turn the system off if you smell gas, see smoke, or hear sparking and schedule a diagnostic for a precise quote.
