About this Service

Fast, Honest Heating Repair When You Need It Most

A heating system failure in South Carolina can go from uncomfortable to genuinely dangerous quickly — especially for elderly family members, young children, or pets. HighTech HVAC treats heating calls as the urgent matter they are. We offer same-day service on most heating repairs and 24/7 emergency dispatch for no-heat situations that can’t wait until morning.

Our technicians are trained and certified to repair every type of residential heating system — gas furnaces, heat pumps, electric air handlers, and packaged units. We carry common replacement parts on every service truck, so most repairs are completed in a single visit. Every repair comes with a written quote before we touch anything and a warranty on parts and labor when we’re done.

Safety Notice

Heating System Failures Can Be a Safety Hazard

Gas furnaces and combustion heating systems can produce carbon monoxide (CO) — a colorless, odorless gas — when they malfunction, crack a heat exchanger, or aren’t properly vented. If you smell gas, notice a yellow or orange burner flame (should be blue), or your CO detector is alarming, leave the home immediately and call 911. Then call us. We perform CO safety checks on every gas heating repair as standard practice — your family’s safety comes first, always.

Warning Signs

Signs Your Heating System Needs Repair

No Heat At All

If your system runs but produces no heat — or won't turn on at all — this is a priority repair. Call us immediately, especially in overnight low temperatures.

Yellow or Orange Burner Flame

A gas furnace flame should burn blue. Yellow or orange flame indicates incomplete combustion — a potential sign of carbon monoxide risk. Do not ignore this.

Short Cycling

Heating system kicks on and off rapidly without completing a full heating cycle. Common causes include dirty filters, oversizing, overheating safeties, or a failing flame sensor.

Insufficient Heat

System runs but can't reach the set temperature, or rooms stay cold regardless of thermostat setting — often points to a failing heat exchanger, dirty filter, or refrigerant issue on heat pumps.

Sudden Spike In Heating Bills

If your energy bill jumps significantly without a change in usage or a cold snap, your heating system is working harder than it should — often a sign of declining efficiency or a developing fault.

Banging, Rattling, or Squeling

Unusual sounds from your furnace or air handler — banging at startup, persistent rattling, or motor squealing — all indicate mechanical problems that worsen over time without repair.

Equipment We Service

All Heating System Types Repaired

Gas Furnaces

The most common heating system in SC homes. We repair all gas furnace issues — igniter failures, heat exchanger cracks, gas valve problems, blower motor failures, limit switch trips, and flame sensor issues. We perform CO safety checks on every gas furnace repair as standard practice.

Heat Pumps

Heat pumps both heat and cool, so a malfunction affects year-round comfort. Common heat pump heating issues include reversing valve failures, refrigerant leaks, defrost control problems, and compressor faults. We service all brands and configurations including dual-fuel systems.

Electric Air Handlers & Strip Heat

Electric heating systems use resistance heat strips inside the air handler. Common failure points include burned-out heat strips, tripped sequencers, failed contactors, and blower motor issues. These repairs are typically faster and more affordable than gas furnace repairs.

Packaged Units

All-in-one packaged gas/electric and packaged heat pump systems require specialized knowledge — we work on them regularly. Common in mobile homes and smaller residences throughout the Manning and Clarendon County area.

Ductless Mini-Split Heating

Mini-split heat pumps provide zoned heating with no ductwork. When heating mode fails — often from refrigerant issues, sensor faults, or communication errors between indoor and outdoor units — we diagnose and repair all major ductless brands.

Full System Diagnostic

Our technician performs a thorough diagnostic on your heating system — testing the heat exchanger, combustion, electrical components, controls, airflow, and safety devices. For gas systems, this includes a carbon monoxide check as standard practice.

Written Quote Before Any Work Begins

We explain exactly what's wrong and what it will cost to fix it before we start. No surprises, no authorizing work over the phone, no bait-and-switch pricing. You decide, then we work.

Repair Completed — Usually Same Visit

We carry the most common heating repair parts on every truck. Most repairs — igniter replacements, flame sensors, blower motors, heat strips, contactors — are completed the same day. We test the system through a complete heating cycle before we leave.

Warranty on Parts & Labor

Every repair is backed by a warranty on both parts and labor. We also walk you through any maintenance steps that can prevent the same issue from recurring, and let you know if we notice anything else on the system that may need attention down the road.

Common Questions

AC Repair FAQs

My heat isn't working — is this an emergency?

It depends on the conditions. If outside temperatures are dropping below 40°F, you have vulnerable family members (elderly, young children, infants) or pets in the home, or you’re seeing any signs of a gas or CO issue (yellow flame, gas smell, alarming detector) — yes, treat it as an emergency and call us immediately. We have 24/7 emergency dispatch and will get to you as quickly as possible. If conditions are mild and the home is staying above 55°F, a same-day or next-day appointment is typically fine.

How much does heating repair cost in Manning, SC?

Heating repair costs vary widely based on the system type and what’s wrong. Common repairs like igniter replacements typically run $150–$300. Blower motor or control board replacements are generally $300–$600. More complex repairs involving heat exchangers or compressors can run higher. We provide a full written quote after diagnosis — before any work begins — so you always know the exact cost upfront.

Do you check for carbon monoxide during a heating repair?

Yes — always. On every gas furnace repair, we check for CO as standard practice. We inspect the heat exchanger for cracks (a common CO source), verify proper venting and combustion, and check flame color. If we detect any CO risk, we’ll tell you clearly and explain your options before leaving the home. Your family’s safety is not optional.

My furnace keeps shutting off after a few minutes — what's wrong?

This is called short cycling, and it’s one of the most common heating complaints. The most frequent causes are a dirty air filter restricting airflow (causing the system to overheat and trip the high limit switch), a failed flame sensor that can’t “see” the burner flame and shuts off as a safety measure, or an overheating issue from a blocked flue or heat exchanger problem. Many of these are same-day repairs once diagnosed.

Should I repair or replace my furnace?

A good rule of thumb: if the furnace is over 15 years old and the repair cost exceeds $800–1,000, replacement is usually the better investment — especially since a new high-efficiency furnace will save significantly on heating bills. If the system is under 10 years old or the repair is relatively minor, fixing it almost always makes more financial sense. We’ll give you an honest assessment and never push a replacement when a repair makes more sense.

My heat pump isn't heating — is that different from a furnace problem?

Yes, heat pump heating failures have different causes than furnace failures. When a heat pump won’t heat, common culprits include a failed reversing valve (which switches the system between heating and cooling mode), low refrigerant charge, a defrost control issue, or outdoor unit problems. Heat pump diagnostics require refrigerant handling certification and different tools — our technicians are fully trained and certified to work on both systems.
