AC Repair & Costs

How much does AC repair cost in Orange County?

AC repair in Orange County typically starts with a diagnostic service call from $75. Common repairs such as capacitor or contactor replacement run $150–$400. Refrigerant recharge runs $150–$500 depending on system type. Compressor replacement costs $1,200–$2,800. All pricing is provided upfront before work begins. Call (714) 908-3868 for a same-day estimate.

Why is my AC not cooling my house in Orange County?

The most common causes are a failed capacitor, low refrigerant from a leak, a dirty condenser coil, or a thermostat set incorrectly. First check your thermostat is set to COOL and the filter isn’t clogged. If the system is running but not cooling, call (714) 908-3868 for same-day diagnosis.

Why is my AC making a loud noise?

Humming without the fan spinning usually indicates a failed capacitor. Grinding or metal-on-metal sounds point to bearing failure. Clicking without startup can mean a failing contactor. Hissing near the line set often indicates a refrigerant leak. Turn off the system and call (714) 908-3868 to prevent further damage.

Should I repair or replace my AC in Orange County?

If your AC is over 12–15 years old and the repair cost exceeds 50% of a new system’s cost, replacement is usually the better investment. If your system uses R-22 refrigerant (phased out in 2020), replacement is almost always the right answer. Pulse Heating and Air provides honest repair vs. replace guidance at every service call. Call (714) 908-3868.

How much does a new AC system cost in Orange County?

A new central AC system in Orange County costs an estimated $5,500–$13,000 installed, depending on system size and home square footage. All pricing is an estimate and will be discussed with you before any work begins. Call (714) 908-3868 for a free in-home estimate.

Furnace Repair & Heating

How much does furnace repair cost in Orange County?

Furnace repair in Orange County typically starts from $150 for common fixes such as igniter replacement or flame sensor cleaning. All estimates are provided upfront. Call (714) 908-3868 for same-day furnace diagnosis.

Why won’t my furnace start?

Common causes include a failed igniter, a dirty flame sensor, a tripped high-limit switch, or a gas supply issue. First check your thermostat is set to HEAT and the filter isn’t blocked. If the furnace won’t light or won’t start at all, call (714) 908-3868 for same-day diagnosis.

Should I repair or replace my furnace?

If your furnace is over 20 years old or has a cracked heat exchanger, replacement is typically the safest and most cost-effective option. For furnaces under 15 years old with a straightforward repair, fixing is usually the right call. Pulse Heating and Air will give you an honest assessment. Call (714) 908-3868.

How much does furnace replacement cost in Orange County?

Furnace replacement in Orange County starts around $3,500 installed for a standard gas furnace. Pricing is an estimate and depends on system size and installation conditions. Call (714) 908-3868 for a free estimate.

Heat Pumps & Mini-Splits

What is a heat pump and is it right for Orange County?

A heat pump is a single system that provides both heating and cooling by moving heat rather than generating it. Orange County’s mild winters make it an ideal climate for heat pumps — the system is most efficient when outdoor temperatures stay above freezing, which is virtually always the case in OC. A heat pump replaces both your AC and furnace in one installation. Call (714) 908-3868.

How much does a heat pump installation cost in Orange County?

Ducted heat pump installation in Orange County starts around $9,500 installed. Pricing is an estimate and depends on home size and installation requirements. Call (714) 908-3868 for a free estimate.

What is a mini-split and when does it make sense?

A ductless mini-split delivers heating and cooling to a specific zone without requiring ductwork. Mini-splits are ideal for homes without existing ducts, older homes like those in Old Towne Tustin, garage conversions, ADUs, and room additions. Single-zone systems start around $3,000 installed. Call (714) 908-3868.

Maintenance & Seasonal Service

When should I schedule an AC tune-up in Orange County?

March and April are the best months — before summer heat arrives and before appointment availability tightens. A spring tune-up includes capacitor testing, refrigerant verification, coil cleaning, and a full system check. Call (714) 908-3868 to schedule.

When should I schedule a furnace tune-up in Orange County?

September and October are ideal — before the first cold nights and while appointment availability is good. A fall furnace inspection includes a CO safety check, heat exchanger inspection, igniter test, and flue inspection. Call (714) 908-3868.

How often should I change my air filter in Orange County?

For most Orange County homes, every 1–3 months depending on filter type and household size. During fire season or Santa Ana wind events, check filters monthly — OC air quality can clog filters significantly faster. A clogged filter is the most common cause of AC and furnace performance problems.

How long does an HVAC system last in Orange County?

Central AC systems typically last 15–20 years with proper annual maintenance. Gas furnaces last 20–30 years. Heat pumps and mini-splits last 15–20 years. Systems that are properly maintained consistently outlast neglected systems by 5+ years. Pulse Heating and Air offers annual maintenance plans starting from $150/year. Call (714) 908-3868.

How do I improve indoor air quality in my Orange County home?

The most impactful steps: upgrade to a MERV 13 filter, install a whole-home UV air purifier, ensure ductwork is properly sealed, and schedule annual maintenance.

What should I do if my AC stops working during a heat wave?

First check: thermostat settings (set to COOL, fan to AUTO), circuit breaker (reset if tripped), and air filter (replace if clogged). If the system won’t start or runs but doesn’t cool, call (714) 908-3868 for same-day emergency AC service throughout Orange County.
