Air Conditioning

Stay Cool When It Matters Most

Northeast Indiana summers bring heat and humidity that can push your cooling system to its limits. Whether your air conditioner is struggling to keep up, making unusual noises, or has stopped working entirely, Complete Custom Heating & Air provides expert AC services designed to restore and maintain your home's comfort.

What We Offer

  • New System Installation — We assess your home's square footage, insulation, ductwork, and layout to recommend a properly sized unit. Oversized systems cycle on and off too frequently, while undersized ones run constantly — both waste energy and shorten equipment life. We install central air systems, ductless mini splits, and heat pumps from trusted brands like York, Fujitsu, and Hisense.
  • AC Repair — From refrigerant leaks and frozen coils to compressor failures and electrical issues, we diagnose problems accurately the first time. We carry common parts on our trucks so many repairs can be completed in a single visit.
  • Seasonal Tune-Ups — A pre-season inspection catches small problems before they become expensive mid-summer breakdowns. We clean the condenser coils, check refrigerant levels, test electrical connections, inspect the blower motor, and verify thermostat calibration.

Signs Your AC Needs Attention

  • Warm or uneven air coming from the vents
  • Higher-than-normal energy bills during cooling season
  • Unusual sounds like grinding, buzzing, or clicking
  • The system cycles on and off frequently (short cycling)
  • Excess humidity indoors despite the AC running
  • Ice forming on the refrigerant lines or evaporator coil

Why Proper Sizing Matters

An improperly sized air conditioner is one of the most common reasons homeowners experience high energy bills and uneven cooling. During every installation, we perform a Manual J load calculation to determine the exact cooling capacity your home needs — not a rough estimate based on square footage alone, but a comprehensive analysis that factors in insulation, windows, sun exposure, and occupancy.

Ductless Mini Split Systems

For homes without existing ductwork, room additions, garages, or spaces with persistent hot spots, ductless mini splits offer an efficient alternative. These systems let you cool individual rooms or zones independently, so you're not paying to cool unoccupied areas. We install and service Fujitsu and Hisense mini split systems.

Dependable Warmth Through Every Indiana Winter

When temperatures drop below freezing in Northeast Indiana, your heating system isn't just about comfort — it's about protecting your family and your home. Frozen pipes, hypothermia risks, and structural damage from ice can all result from a failed heating system. We work on furnaces, boilers, heat pumps, and hydronic systems to keep your home warm and safe all winter long.

Our Heating Services

  • Furnace Installation & Replacement — Whether you're upgrading a 20-year-old unit or installing heating in a new build, we help you choose the right furnace based on fuel type (natural gas, propane, or electric), efficiency rating, and your home's heat load. High-efficiency furnaces with AFUE ratings of 96% or higher can significantly reduce your heating costs compared to older 80% efficient models.
  • Boiler Services — We install, repair, and maintain hot water and steam boilers, including Weil-McLain and Navien units. Boiler systems offer even, quiet heat and are common in older Northeast Indiana homes. We handle everything from circulator pump replacements to complete system overhauls.
  • Heat Pump Systems — Heat pumps provide both heating and cooling in a single system. Modern cold-climate heat pumps can operate efficiently even in sub-zero temperatures, offering a lower operating cost compared to traditional furnaces, especially when paired with an electric rate plan.
  • Heating Repairs — No heat is an emergency. We offer prompt repair service for furnaces that won't ignite, boilers with leaking valves, heat pumps stuck in defrost mode, and everything in between.

Warning Signs Your Heating System Needs Service

  • The furnace or boiler takes longer than usual to heat the house
  • You notice a yellow or flickering burner flame instead of a steady blue
  • Unexplained increases in your gas or electric bill
  • The system makes banging, rattling, or popping noises
  • Rooms heat unevenly, with some staying cold
  • The unit is more than 15 years old and needing frequent repairs

Gas vs. Electric: What's Right for Your Home?

The best heating system depends on what fuel sources are available at your property, your local utility rates, and your home's existing infrastructure. Natural gas furnaces typically offer lower operating costs in areas with gas service, while electric heat pumps can be the most efficient option where gas isn't available. We'll walk you through the real costs — not just equipment price, but 10-year operating cost projections — so you can make an informed decision.

Carbon Monoxide Safety

Any fuel-burning heating equipment — furnaces, boilers, water heaters — produces combustion byproducts including carbon monoxide. Cracked heat exchangers, blocked flue pipes, and poor ventilation can allow CO to enter your living space. During every heating inspection, we perform a combustion analysis and check for CO leaks to make sure your system is operating safely.

Indoor Air Quality

Breathe Easier in Your Own Home

The air inside your home can contain two to five times more pollutants than outdoor air, according to the EPA. Dust, pet dander, pollen, mold spores, volatile organic compounds from household products, and even bacteria circulate through your HVAC system every time it runs. Our indoor air quality solutions work alongside your existing heating and cooling system to remove contaminants and control humidity levels.

IAQ Solutions We Provide

  • Whole-Home Air Purification — Unlike portable room purifiers, whole-home systems are installed directly in your ductwork and treat every cubic foot of air that passes through your HVAC system. We install Aprilaire and other high-efficiency media filters, UV-C germicidal lights, and electronic air cleaners that capture particles as small as 0.1 microns.
  • Humidifiers & Dehumidifiers — Indiana winters dry out indoor air, causing static electricity, cracked woodwork, dry skin, and increased susceptibility to respiratory infections. Summer humidity invites mold growth and makes your AC work harder. We install whole-home humidifiers and dehumidifiers that maintain ideal moisture levels (between 30% and 50% relative humidity) automatically.
  • Ventilation Systems — Tightly sealed, energy-efficient homes sometimes trap stale air. Energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs) bring in fresh outdoor air while recovering the energy from the outgoing air, so you get ventilation without wasting heating or cooling dollars.
  • Duct Cleaning & Sealing — Leaky ductwork can pull in dust, insulation fibers, and contaminants from attics and crawl spaces. We inspect, seal, and clean duct systems to improve both air quality and system efficiency.

Signs of Poor Indoor Air Quality

  • Family members experience allergy-like symptoms only at home
  • Visible dust accumulates quickly on surfaces after cleaning
  • Musty or stale odors that don't go away with cleaning
  • Condensation on windows during winter months
  • Mold growth around vents, in bathrooms, or in the basement
  • Persistent dryness — cracking paint, static shocks, dry throat
Improve Your Air Quality

Why Standard Filters Aren't Enough

The basic 1-inch filters that come with most furnaces are designed to protect the equipment, not your lungs. They catch large dust particles but let allergens, bacteria, and fine particulates pass right through. Upgrading to a 4-inch or 5-inch media filter or adding a UV germicidal light can dramatically reduce airborne contaminants without restricting airflow — something that high-MERV 1-inch filters can actually cause.

Humidity & Your Health

Proper humidity levels do more than protect your hardwood floors and furniture. Research shows that viruses survive longer and spread more easily in dry air. Maintaining indoor humidity above 40% during winter months can reduce airborne virus transmission and support your respiratory system's natural defenses.

Thermostats

Smarter Control Over Your Home's Comfort

Your thermostat is the brain of your HVAC system. An outdated or poorly configured thermostat can waste energy, cause uneven temperatures, and make your equipment work harder than it needs to. We install and configure smart and programmable thermostats that let you optimize comfort and efficiency, whether you're home, away, or asleep.

Thermostat Services

  • Smart Thermostat Installation — We install Honeywell Home, Ecobee, and other leading smart thermostats. Smart thermostats learn your schedule, adjust temperatures based on occupancy, and can be controlled from your phone. Some models include room sensors that balance temperatures across multiple areas of your home instead of relying on a single reading from the hallway.
  • Programmable Thermostat Setup — Not everyone wants a Wi-Fi thermostat, and that's fine. A well-configured programmable thermostat can save up to 10% on annual heating and cooling costs by automatically lowering the temperature when you're sleeping or away from home. We'll program it to match your household's actual schedule.
  • Wiring & Compatibility Assessment — Not all thermostats are compatible with all HVAC systems. Heat pumps, two-stage furnaces, zoned systems, and boilers each require specific thermostat wiring and configuration. We assess your system and wiring before recommending a thermostat to ensure it works correctly from day one.
  • Zoning Systems — If your home has hot and cold spots, a zoning system with multiple thermostats and motorized dampers can direct heated or cooled air where it's needed most. This eliminates the problem of overcooling the downstairs to keep the upstairs comfortable.

Signs It's Time for a Thermostat Upgrade

  • Your current thermostat is a non-programmable manual model
  • The displayed temperature doesn't match how the house actually feels
  • Your HVAC system short cycles or runs constantly
  • You want remote access to adjust settings while traveling
  • Different floors or rooms have significant temperature differences

The Real Value of Smart Thermostats

Beyond convenience, smart thermostats provide usage reports that show exactly when your system runs and how much energy it uses. This data helps identify problems early — if your system suddenly starts running 30% more hours than normal, that's a sign something needs attention before it becomes an expensive repair. Some utility companies also offer rebates for smart thermostat installation.

Common Wiring Issues We Fix

Many DIY thermostat installations run into wiring problems. Older homes may lack a C-wire (common wire) that most smart thermostats require for continuous power. We can run new wiring, install add-a-wire adapters, or recommend thermostats that include battery backup options so your new thermostat works reliably without jury-rigged workarounds.

System Maintenance

Prevent Breakdowns Before They Happen

Most HVAC breakdowns are preventable. Dirty filters, worn belts, loose electrical connections, and low refrigerant levels cause the majority of emergency service calls — and all of them can be caught during a routine maintenance visit. Regular professional maintenance keeps your equipment running at peak efficiency, extends its lifespan, and protects your manufacturer warranty.

What's Included in a Maintenance Visit

  • Cooling Season Tune-Up — We clean the outdoor condenser coil, check refrigerant charge, inspect the evaporator coil, test the capacitor and contactor, lubricate moving parts, inspect the condensate drain, verify thermostat operation, and measure airflow across the system.
  • Heating Season Tune-Up — We inspect the heat exchanger for cracks, clean and test the burner assembly, check gas pressure, inspect the flue and venting, test safety controls, check the ignition system, measure carbon monoxide levels, and verify proper airflow.
  • Filter Replacement — We check and replace filters as needed. A clogged filter is the number one cause of HVAC inefficiency and premature failure. We'll recommend the right filter type and replacement schedule for your specific system.
  • Full System Inspection — Beyond the mechanical components, we inspect electrical connections, ductwork conditions, thermostat calibration, and overall system performance. You'll receive an honest assessment of your system's condition and any recommended repairs — no pressure, no scare tactics.

Why Maintenance Pays for Itself

  • Well-maintained systems use 15-25% less energy than neglected ones
  • Catch small problems before they become major repairs
  • Extend equipment life by 5-10 years beyond the average
  • Maintain your manufacturer's warranty coverage
  • Reduce the chance of an inconvenient mid-season breakdown
  • Improve indoor air quality by keeping components clean
Schedule Maintenance

How Often Should You Schedule Maintenance?

The industry standard is twice a year — once in spring for your cooling system and once in fall for your heating system. This timing ensures each system is inspected and tuned before the season when you'll rely on it most. If you have a heat pump that handles both heating and cooling, we still recommend two visits because different components are stressed during each season.

Our Honest Approach

We don't use maintenance visits as a sales pitch for unnecessary equipment. If your 15-year-old furnace is running well and passes all safety tests, we'll tell you it's running well. When we do recommend repairs or replacement, we'll explain exactly why and give you the information to make your own decision. That's the difference when you work with a company that values your trust.

Repair vs. Replace: How We Help You Decide

We use a straightforward rule of thumb: if the repair cost exceeds 50% of a new system's value and the equipment is past its expected lifespan, replacement usually makes more financial sense. But we never push replacements. We'll show you both options — the repair cost and the long-term replacement cost — and let you decide what's right for your budget and situation. Plenty of older systems have years of reliable service left with a well-done repair.

Why Accurate Diagnosis Matters

Replacing parts by guessing is expensive and frustrating. We use systematic diagnostic procedures — measuring pressures, temperatures, voltages, and amp draws — to identify the actual cause of the problem, not just the symptom. A system blowing warm air could be a refrigerant leak, a failed compressor, a bad capacitor, or even a thermostat wiring issue. Each has a very different repair cost, and the right diagnosis means you only pay for what you actually need.
