Step 1 of 3: Equipment

What kind of equipment?*

One month of real heat, but Lakewood's storms are the bigger test

Lakewood only asks your air conditioner to work through July, with afternoons averaging 80°F. That is not a long season, but the unit still needs to be ready when it hits, and a short season means problems can sit unnoticed since the system runs so little the rest of the year.

The bigger wear comes from what is outside the unit. Jefferson County has logged 152 hail events and 114 damaging wind events over the past ten years, with hail as large as 2.75 inches. That kind of weather bends fins on the outdoor coil and can knock the unit around on its pad. A tune-up is when a contractor catches that damage, straightened fins, a coil that needs cleaning, a unit that has shifted, before July's heat asks the system to work through it.

1 months: July through July, your air conditioner is on duty
80°F: the average summer afternoon it cools against
152 hail events: in ten years, and hail bends the fins on outdoor coils
114 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in June, before homes here start needing cooling in July.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.

What does AC maintenance include?: A contractor checks refrigerant pressure, tests the capacitor, cleans the condenser coil, and clears the condensate drain so it doesn't back up. They also check the electrical connections and confirm the system is cycling on and cooling like it should. A coil caked with dust or debris makes the whole system work harder than it needs to, so cleaning it is one of the more important parts of the visit.
How often does an air conditioner need maintenance?: Once a year, before the heat sets in. Lakewood's cooling season runs through July, with summer afternoons averaging 80°F, so a spring visit gives a contractor time to catch a weak capacitor or a dirty coil before the system has to work through the season. An older unit or one that's needed a repair recently may be worth a second look partway through summer.
Is AC maintenance worth it?: Yes. A yearly checkup catches the small failures, a weak capacitor, a coil crusted with debris, a low refrigerant charge, before they leave you without cooling. Lakewood has also logged 152 hail events and 114 damaging wind events over the past ten years, and a maintenance visit is a chance for a contractor to spot storm damage to the outdoor unit before it turns into a bigger repair.
