## Signs that point to a heating or cooling fault

Most faults show up as something you can see, hear or feel. These are common signs and what usually sits behind them.

-   ### Vents blowing air that never cools
    
    The system runs, but the air stays warm. A dirty outdoor coil, a failed capacitor or low refrigerant are common causes.
    
-   ### Frost along the copper lines
    
    Ice on the lines usually means the indoor coil is too cold, from a clogged filter or low refrigerant. Switch cooling off and let the ice melt.
    
-   ### Starts, stops, starts again
    
    A system that runs in short bursts may be overheating, reacting to a faulty thermostat or choking on poor airflow. Oversized equipment can do it too.
    
-   ### A wet floor by the furnace or air handler
    
    Cooling makes water that should leave through a drain line. A clog or a cracked pan lets it spill at the indoor equipment.
    
-   ### A breaker that won't stay on
    
    Repeated tripping can point to a failing motor, a worn compressor or damaged wiring. Reset it once, then leave it off if it trips again.
    
-   ### Burners that light, then shut off
    
    A dirty flame sensor or an overheated heat exchanger can shut a furnace down soon after it lights. A clogged filter is often behind the overheating.

## What HVAC in Spanish Fork covers

HVAC means the heating, cooling and airflow equipment in a house. Work on HVAC in Spanish Fork can involve a furnace, an air conditioner, a heat pump, or the ducts and controls that tie them together. HVAC repair in Spanish Fork is what you need when the house won't hold its temperature, or when the equipment starts acting differently.

We connect you with a licensed, insured HVAC contractor. The call goes to a phone line that connects callers with licensed, insured independent contractors, and where a contractor is available, the line connects the call to that contractor. That contractor then confirms availability and fees.

## How the heating, cooling and airflow parts work together

The thermostat tells the system when to run. A blower then pulls house air through the return ducts and the filter. It pushes that air past a heat source or a cold coil and sends it back through the supply vents.

Each system changes the air in its own way:

-   A furnace burns gas and warms the air across a metal heat exchanger.
-   An air conditioner uses refrigerant to pick up heat at the indoor coil and release it outside.
-   A heat pump moves heat the same way, and it can reverse direction to warm the house in winter.

The blower, filter, ducts and thermostat are shared. A weak shared part can cause trouble in both seasons, and [the guide to shared parts](/hvac-spanish-fork/furnace-and-ac-both-not-working/) walks through them.

Airflow is one place a system can fail. A clogged filter can starve an indoor coil until it freezes, and the same filter can overheat a furnace until a safety switch shuts the burners off. Other faults are electrical, such as a worn capacitor or a failed motor. Refrigerant leaks and blocked drain lines cause their own set of symptoms.

## Which symptom points to which service

Start with what you can see or feel, then read the service or guide that fits it.

| What you notice | Where to read next |
| --- | --- |
| The AC runs, but the air coming out isn't cold | AC repair in Spanish Fork and warm air on summer afternoons |
| The AC won't start at all | thermostat, breaker and outage checks |
| Frost on the copper lines, or a wet floor at the indoor equipment | what to switch off and check |
| The system keeps starting and stopping | short cycling explained |
| The furnace blows cold or quits on a freezing night | furnace repair in Spanish Fork and why a furnace quits |
| A heat pump struggles in heating or cooling mode | heat pump repair in Spanish Fork |
| An old AC keeps failing | repairing or replacing an old AC and AC installation in Spanish Fork |

A new rattle, squeal or bang usually belongs with whichever system was running when it started.

## Older and newer homes fail in different places

About 25% of the 12,630 homes in Spanish Fork were built before 1980, and about 53% of the 12,630 homes in Spanish Fork were built in 2000 or later. The age of a house changes what a contractor looks for.

| Part | Older house | Newer house |
| --- | --- | --- |
| Ducts | Joints may have loosened, and the ducts may have been sized for earlier equipment | The ducts are younger, but a kinked flexible run can still cut airflow |
| Equipment | A furnace or AC may be a later swap attached to earlier ductwork and wiring | The equipment may be original to the house, with parts starting to wear |
| Venting and drains | A furnace may vent through a metal flue | A high-efficiency furnace may vent through plastic pipe and drain water through a condensate line |
| Controls | A simple wall thermostat may run on older wiring | A programmable thermostat has more settings to check |

## Safe checks before you call

These checks need no tools, and no panels come off.

-   Confirm the thermostat is set to the right mode and temperature, and replace its batteries if it uses them.
-   Pull the air filter and hold it up to a light. Swap it if you can't see through it, and read [how often to check a filter](/how-often-to-change-hvac-air-filter/).
-   Look at the breaker for the equipment. Reset it once, and if it trips again, leave it off.
-   Pull leaves, plants and stored items back from the outdoor unit, and keep your hands away from its fan.
-   Open any closed supply vents and move furniture off the returns.

If the whole house is dark, the HVAC system may not be the problem. Spanish Fork Power & Light provides electric service to homes and businesses in Spanish Fork.

Stop there. Refrigerant work, wiring, gas valves and burners, and sealed parts are for a licensed contractor.

## If you smell gas or a carbon monoxide alarm sounds

If you smell gas, leave the house, then call the gas utility from outside. If a carbon monoxide alarm sounds, get everyone out and call emergency services.

Don't try to find the cause or restart the equipment yourself. A licensed contractor handles any work on gas parts and venting.

## What a contractor usually does on a visit

A licensed contractor usually starts by confirming the symptom, then tests the parts behind it. That can mean measuring airflow, checking electrical parts and watching the burners cycle. It can also mean reading refrigerant pressures or clearing a blocked drain. For more detail, see [what a contractor checks on a furnace](/furnace-repair-spanish-fork/what-happens-during-furnace-repair/) and [what to ask on an AC visit](/what-to-expect-ac-repair-visit/).

The contractor then usually explains what failed and the options, such as repair or replacement. Ask why the part failed and what each option involves. It can help to read about [repairing or replacing an older furnace](/furnace-repair-spanish-fork/repair-or-replace-furnace/) as well.

Spanish Fork City lists HVAC replacements among the common projects covered by a residential permit, so ask about it if a replacement comes up. If a job involves a gas line, ask about that too. Enbridge Gas lists Spanish Fork among the cities on its construction contacts page for gas lines and new service.

## How the weather wears on equipment

The NOAA weather station near Spanish Fork averages 5,415 heating degree days a year. The same station averages 1,013 cooling degree days a year. A higher count means more demand on that side of the system, so a furnace or a heat pump in heating mode carries the bigger load.

The average June to August daily high at the NOAA weather station near Spanish Fork is 89.8°F. Heat like that tests an outdoor coil and a starting capacitor.

The average December to February daily low at the NOAA weather station near Spanish Fork is 23.5°F. Cold like that keeps a furnace's burners, blower and safety switches cycling. It can also push a heat pump onto its backup heat.

## Routine care that heads off faults

The filter is worth checking often while the system is working through the heating or cooling season, and change it when it's clogged. A licensed contractor can advise how often the system needs service. Keep the outdoor unit clear all year. The [spring and fall HVAC checklist](/hvac-spanish-fork/spring-and-fall-hvac-checklist/) lays out the rest.

Contractor checks usually follow the seasons, with the furnace in fall and the AC in spring. A heat pump works in both seasons, so it's often checked in both. During those checks, a licensed contractor usually cleans coils, clears drain lines and tests electrical parts.

## What makes an HVAC job larger or smaller

-   Which part failed makes a big difference. A failed capacitor is a smaller job than a failed compressor.
-   Access matters, because a furnace in a tight attic or crawl space is harder to work on.
-   The age and type of the system count, since parts for older equipment can be harder to find.
-   The visit can turn up more work, such as a leak or a damaged duct found while tracing the fault.
-   The job grows if it moves from a repair to a replacement, which can also involve ducts or wiring.

Each independent contractor confirms its own fees.

## What Spanish Fork's weather and permits mean for HVAC equipment

Summer highs and winter lows put different loads on different parts of a system. A replacement also raises a permit question worth asking about.

-   ### Long runs on hot days
    
    The NOAA weather station near Spanish Fork averages 60 days a year with a high of 90°F or more, and an AC runs in long stretches on days like those.

## Questions about HVAC repair

-   ### What does HVAC repair cover?
    
    It covers faults in the furnace, the air conditioner, the heat pump and the ducts and controls that link them. A licensed contractor finds the cause and explains what failed and the options.
    
-   ### Which checks are safe to do myself?
    
    You can check the thermostat settings and batteries, the air filter and the vents and returns. You can also clear around the outdoor unit and reset a tripped breaker once.
    
-   ### What should I do about a gas smell or a carbon monoxide alarm?
    
    If you smell gas, leave the house, then call the gas utility from outside. If a carbon monoxide alarm sounds, get everyone out and call emergency services.
    
-   ### What changes the cost of an HVAC repair?
    
    The failed part, how easy the equipment is to reach and the age of the system all change the size of the job. Each independent contractor confirms its own fees.
    
-   ### When is a contractor available?
    
    Service availability and appointment times depend on the independent contractor, who confirms them when you call.
    
-   ### Should I repair or replace my system?
    
    It depends on what failed, the age of the system and how the rest of it is holding up. Ask the contractor to explain what failed and what each option involves.
    
-   ### Does replacing HVAC equipment need a permit?
    
    Ask the contractor whether the job needs a permit. That question matters most when equipment is being replaced rather than repaired.
