# Your HVAC maintenance schedule in Pueblo, season by season

Published by Fieldstone Online

## An HVAC routine for Pueblo's heating and cooling seasons

An HVAC maintenance schedule in Pueblo comes down to a check-in before the AC season and another before the furnace season. Each has a short list a homeowner can handle and a longer list that belongs to a licensed contractor.

Do the small items yourself. Leave anything that involves gas, wiring or refrigerant alone.

## Why does each season get its own check?

The furnace and the air conditioner run in different months, and they wear in different ways. A cooling check done in spring tells you little about the burner you will need in November.

In a typical year at the NOAA weather station near Pueblo, 74 days reach a high of 90°F or more and 152 days fall to a low of 32°F or below. Both seasons are real ones for the equipment, so each deserves its own look before it starts.

The same station logs 5,386 heating degree days a year (base 65°F) and 1,060 cooling degree days a year (base 65°F). Degree days add up how far daily temperatures sit from that baseline. A bigger total means the equipment is asked to do more, and the heating total is the larger of the two.

## What can you check before cooling season?

Start with the thermostat, the filter, the outdoor unit and the airflow at the registers. These checks need a screwdriver and a garden hose at most.

1.  Set the thermostat to cool and a few degrees below the room temperature. If the screen is dim, swap the batteries first.
2.  Slide out the filter. If it is gray and furry with dust, replace it. ENERGY STAR advises inspecting, cleaning or changing air filters in a central air conditioner, furnace or heat pump once a month.
3.  Walk outside to the condenser, the square box with a fan on top. Turn the power off at the thermostat and the breaker, then pull weeds, leaves and cobwebs away from it.
4.  Move furniture, rugs and curtains off the registers and return grilles so air can move.
5.  Check the breaker panel. If the AC breaker has tripped, reset it one time. If it trips again, stop.

Checking the filter is its own habit, and [the filter guide](/how-often-to-check-furnace-and-ac-filter/) covers how to do it. The reason it matters is plain: ENERGY STAR says a dirty filter can increase energy costs and damage equipment, and that wear can cut the equipment's life short.

How do you tell it worked? Air at the registers feels cooler than the room, and the outdoor fan runs with a steady sound. If the air stays warm, ice shows on the refrigerant lines or water collects at the indoor unit, stop checking and treat it as a fault.

## What can you check before heating season?

Run the same filter, thermostat and vent checks, then add the items that belong to a furnace. The goal is to catch a setting or a blocked path before the first cold night.

Set the thermostat to heat and raise the setting above the room temperature. Listen as the furnace starts. A furnace that lights, runs a full cycle and warms the rooms is behaving. One that lights and then drops out, makes a new noise, or leaves some rooms cold needs a contractor.

Keep boxes, paint cans and laundry baskets away from the furnace and the water heater. Burners need open space around them to draw air.

Press the test button on each carbon monoxide alarm and replace the batteries if the alarm maker says to. Then read the two safety lines that apply to any furnace.

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.

## Which tasks belong to a licensed contractor?

The US Department of Energy says regular maintenance, such as charging refrigerant and replacing filters, is necessary to keep central air conditioners at peak performance. Filters are yours to replace. Refrigerant is not.

Refrigerant is sealed in copper lines under pressure, and adding or removing it takes gauges and training. A low charge also usually means a leak, which a top-up does not repair.

A licensed contractor typically handles these items:

-   Checking the refrigerant charge and looking for leaks.
-   Tightening electrical connections and testing the capacitor and contactor.
-   Cleaning the indoor and outdoor coils.
-   Inspecting the burner, the ignition and the flue pipe that carries exhaust out.
-   Clearing the condensate drain, the line that carries water away from the indoor unit.

That list is general. Ask the contractor what applies to your equipment and how often it advises service, since that depends on the system.

## When does a check turn up a fault worth a call?

Some findings are ordinary housekeeping, such as a gray filter. Others point past the homeowner list.

Call about a fault when you see any of these:

-   Warm air from the registers after the filter and thermostat check out.
-   Ice on the refrigerant lines or the outdoor unit.
-   An AC that switches on and off in short bursts.
-   A breaker that trips again after a reset.
-   A puddle under the indoor unit.
-   A furnace that lights and drops out.

Age matters too. ENERGY STAR suggests considering replacement when a heat pump or air conditioner is more than 10 years old, and when a furnace or boiler is more than 15 years old. Those are points to weigh with a contractor, not deadlines.

Running a system with a fault tends to add strain to parts that were fine. A small repair found at a seasonal check is usually easier to judge than a failure in the middle of a hot or freezing stretch.

## Asking a contractor about a seasonal tune-up

If your checks found a fault, or you want a licensed contractor to handle the refrigerant, burner and wiring side, the details are on [the Pueblo HVAC page](/).

## Maintenance schedule questions

-   ### Can I skip the seasonal checks if the system runs fine?
    
    A system can run and still have a dirty coil, a weak part or a venting problem. The homeowner checks catch the easy items, and a licensed contractor looks at the parts that are not safe to open.
    
-   ### How often should I change the air filter?
    
    Check it often and replace it when it looks gray and clogged. The contractor advises how often your particular equipment needs service.
    
-   ### Who sets the fees for a seasonal check?
    
    Each independent contractor confirms its own fees.
    
-   ### Can I rinse the outdoor unit myself?
    
    Only after the power is off at the thermostat, the disconnect and the breaker. Pull leaves and weeds away by hand, then rinse the outside gently. Bent fins, refrigerant lines and electrical parts are for a licensed contractor.
    
-   ### What should I do if I smell gas while checking the furnace?
    
    If you smell gas, leave the house, then call the gas utility from outside. Do not use the phone line on this site for a gas smell.
