AC Repair in Longmont, CO

Reliable Air Conditioning Repair for Longmont Homes

It is the first real hot stretch of the summer, and your air conditioner is blowing warm air across the living room. You bump the thermostat down, wait, and nothing changes except the temperature slowly creeping up. And by dinner, the whole house feels like an oven.

That is where we come in. High 5 Plumbing, Heating, Cooling & Electric has been handling AC Repair in Longmont, CO since 2012, and you can reach a real person any time at (720) 615-9621. We are licensed and insured under Colorado License #189849, and calls are answered by an actual human, not a call center, 24 hours a day.

What Goes Wrong With an AC System

Air conditioners fail for a lot of reasons, and rarely at a convenient time. Sometimes it is a small part that quietly gives out. Other times it is a bigger problem that has been building for months.

Here are the issues we see most often on service calls:

Warm air coming from the vents
Weak or reduced airflow
Refrigerant leaks and low charge
Frozen evaporator coils
Strange noises like grinding, buzzing, or clicking
A unit that turns on and off constantly
Water pooling near the indoor unit

The reality is that a struggling AC only gets worse the longer it runs that way. A minor refrigerant issue can turn into a compressor failure, and that is a far more expensive repair. But catching things early keeps costs down and keeps your home comfortable through the hottest days along the Front Range.

Our Approach to AC Repair in Longmont, CO

When one of our technicians arrives, the first job is finding the actual cause of the problem, not just treating the symptom. We diagnose the system, explain what we find in plain language, and give you the price before any work starts. No hidden fees and no surprises when the job is done.

Every technician is background-checked, so you know exactly who is coming into your home. And because we stand behind our work with a 100% satisfaction guarantee, you are not left wondering whether the repair will hold up.

The good news is that we service most major brands regardless of who installed the system originally. We install and service Rheem and Ruud equipment, and we work on units from most other manufacturers as well. If your AC can be repaired, we will repair it. If replacement makes more financial sense, we will tell you that honestly.

Longmont sits at the base of the foothills, where summer afternoons can heat up fast and a working AC is not a luxury. When it quits, you want a company that shows up and does the job right the first time.

Upfront pricing with the cost confirmed before work begins

Common Questions About AC Repair

Here are common questions we hear from customers in Longmont.

How quickly can you come out?

We are available 24/7, so you do not have to wait until business hours when your AC fails on a Saturday afternoon. Call (720) 615-9621 and a real person will help you schedule service.

Should I repair or replace my AC?

It depends on the age of the unit, the cost of the repair, and how well the system has been maintained. Our technician will lay out the numbers for both options so you can make the call with real information in front of you.

Do you work on my brand of AC?

Most likely, yes. We service most major brands no matter who installed the equipment, and we install Rheem and Ruud systems when a replacement is the better path.

Why is my AC running but not cooling?

This often points to low refrigerant, a frozen coil, or a compressor problem. Each has a different fix, which is why an accurate diagnosis matters so much before any repair begins.
