Why spring, in Pueblo
A typical Pueblo summer means a long stretch of hard running: 89 days at 90°F or hotter in 2024, 70 in 2025. A part that’s marginal in May — a capacitor losing strength, a contactor with pitted contacts, a coil caked with dust, a drain line slowly filling with slime — usually fails during that stretch, not before it.
A tune-up finds those parts while the weather is mild and a repair is a scheduled visit rather than an emergency. It’s also the time to ask whether an aging system is likely to make it through another summer.
What our technicians check
The list follows ENERGY STAR’s maintenance checklist for cooling equipment.
| Coils | Inspect and clean the outdoor condenser coil; check the indoor evaporator coil. Dirty coils cut the system’s ability to move heat and make it run longer. |
|---|---|
| Refrigerant charge | Measure it. Too much or too little reduces efficiency and can shorten the compressor’s life — and a low charge means a leak to find. |
| Electrical | Tighten connections, measure voltage and current on the motors, and test the capacitor and contactor. |
| Condensate drain | Inspect and flush the drain line and pan, and test the float switch if there is one. |
| Airflow | Filter, blower, and the return path. Too little air across the indoor coil is how coils freeze. |
| Controls | Check the thermostat settings and run the system through a full start, cooling cycle and shutdown. |
| Moving parts | Lubricate where the equipment calls for it; check the fan blade and motor. |
Have a swamp cooler too? The spring start-up — new pads, pump, float and belt — is its own job. See swamp cooler service.
Your part between visits
- Check the filter monthly through summer; change it at least every three months.
- Keep plants, weeds and stored items about two feet back from the outdoor unit.
- Keep return grilles clear of furniture and rugs.
- If you notice ice, water around the indoor unit, or new noises, call before it becomes a breakdown.
Questions we hear
When should I book it?
Spring — before the first run of 90-degree days. In Pueblo those can arrive in June: in 2025 the year’s 103-degree high came on June 20 and again on June 21. Once a heat wave starts, the calls are about breakdowns, and a tune-up is easier to schedule when nobody’s house is hot yet.
How often should I change the filter in summer?
ENERGY STAR’s advice is to check it every month and change it at least every three months. During long cooling stretches, check it more often; a filter that looks gray and clogged should go regardless of the calendar.
What can I do myself between visits?
Change the filter, keep weeds, plants and stored items about two feet back from the outdoor unit, and keep return grilles clear. Cleaning the coil properly means opening the cabinet with the power off, and the electrical parts and refrigerant side belong to the technician.
