AC Maintenance in Longmont, CO

Reliable AC Tune-Ups for Longmont Homes

High 5 Plumbing, Heating, Cooling & Electric provides professional AC maintenance for homeowners across Longmont and the surrounding Front Range communities. We service air conditioners of every make and model, and we do it with upfront pricing and technicians who show up ready to work.

You can reach us at (720) 615-9621, and when you call, a real person answers, not a call center. We have been serving the Denver metro since 2012, and we are licensed and insured under Colorado License #189849. That combination matters when you are trusting someone to service the system that keeps your home comfortable through a hot Colorado summer.

Why AC Maintenance Matters in Longmont

Situated along the Front Range at the base of the foothills, Longmont sees real summer heat, and your air conditioner works hard to keep up. When a system runs season after season without a tune-up, small issues turn into big ones. Dirty coils, low refrigerant, worn parts, and clogged filters all force the unit to run longer and harder than it should.

Here is the problem: most of these issues are invisible until the system breaks down on the hottest day of the year. And a breakdown almost always costs more than the maintenance that would have prevented it.

That is where we come in. Routine AC maintenance catches wear before it becomes failure. It keeps your energy bills in check, extends the life of the equipment, and helps the air in your home stay clean and comfortable. The reality is that a well maintained system simply lasts longer and runs cheaper.

What Our AC Maintenance Includes

When our technicians perform AC maintenance, we go through the full system rather than a quick glance. We inspect and clean the parts that matter, check performance, and flag anything that needs attention before it leaves you sweating.

A typical visit covers items like these:

Inspecting and cleaning the condenser and evaporator coils
Checking refrigerant levels and looking for leaks
Testing electrical connections and components
Replacing or cleaning air filters
Clearing the condensate drain line
Measuring airflow and overall system performance

Even better, we tell you exactly what we find. You get straightforward answers about the condition of your unit, and if something needs repair, you hear about it with the price attached before any work begins. No hidden fees, ever.

For a system as important as your AC, that kind of ongoing care pays off.

We also run our High 5 Cares community program, which spotlights a local nonprofit every month. Serving Longmont means more to us than just showing up for the job.

When to Schedule AC Maintenance

The best time to service your air conditioner is before you need it, ideally in spring, before the first real heat wave rolls through. But honestly, any time is better than no time. If it has been more than a year since your last tune-up, your system is overdue.

The catch is that everyone tends to call at once when summer arrives. Booking your maintenance early means you get on the schedule before the rush and head into the hottest months with a system you can trust.

And because we are available 24/7, you are never stuck waiting if something does go wrong. Whether it is a routine tune-up or an emergency at midnight, we are ready.

Questions Longmont homeowners ask us most.

How often should I get AC maintenance?

Once a year is the standard recommendation for most home air conditioning systems. Annual service keeps the unit running efficiently and helps catch small problems before they turn into expensive repairs.

Do you service systems you did not install?

Yes. We work on most major brands regardless of who installed the unit originally, so you are welcome to call us even if another company put in your system.

Will I know the cost before you start?

Absolutely. We provide upfront pricing before any work begins, so you always know what you are paying with no surprises when the job is done.
