Trusted Heating & Cooling Services for Longmont Homes

Longmont sits along the Front Range of Colorado, right at the base of the foothills, where summer afternoons can heat up fast and homes range from older builds to newer neighborhoods. And when the temperatures climb, an aging or undersized air conditioner just cannot keep up with the demand.

That is where we come in. High 5 Plumbing, Heating, Cooling & Electric has been serving the Denver metro since 2012, and we handle AC Installation in Longmont, CO, with a level of care most homeowners are not used to. Give us a call at (720) 615-9621, and a real person answers, not a call center, 24/7.

When It Is Time for a New Air Conditioner

Some homeowners hold onto an old AC unit far longer than they should. But there are clear signs it is time to replace rather than repair.

The reality is that an air conditioner past its prime costs you more every month. Rising energy bills, uneven cooling from room to room, frequent breakdowns, and a system more than a decade old all point in the same direction. And in a climate where cooling matters through the warm months, limping along with a failing unit is not worth the stress.

Here is the problem: choosing the wrong size or type of system can leave you uncomfortable and paying too much. A unit that is too small runs constantly, while one that is too large cycles on and off without properly removing humidity. Our background-checked technicians take the time to size the system correctly for your home and your budget.

Our Cooling Services

AC Installation in Longmont, CO, is one piece of what we do. We handle the full range of cooling needs so your home stays comfortable no matter the season:

Not sure which option fits your home? A ductless mini split might make sense for an addition or a space without existing ductwork, while a heat pump can cover both heating and cooling. We walk you through the choices before any work begins.

What to Expect From Your Installation

A good installation is about more than swapping out equipment. Our team evaluates your ductwork, checks your home’s layout, and confirms the right system for the space. Then we install it properly the first time.

Even better, you know the cost before we start. We give you transparent, upfront pricing with no hidden fees, so there are no surprises when the job is done. And if the investment feels like a lot all at once, financing is available to make a new system easier to manage.

We install and service trusted brands like Rheem and Ruud, and we service most major brands regardless of who put the original system in. So whether you are replacing a worn-out unit or upgrading to something more efficient, we have you covered.

Frequently Asked Questions

Before you call, here is what most people ask.

How long does an AC installation take?

Most standard installations are completed in a single day. But the exact timeline depends on your home, your ductwork, and the type of system you choose. We give you a clear estimate before we start.

What size air conditioner do I need?

That depends on your home’s square footage, insulation, layout, and a few other factors. The good news is that our technicians handle the sizing calculation for you, so you get a system matched to your space rather than a rough guess.

Should I repair or replace my AC?

If your unit is more than a decade old, breaks down often, or drives up your energy bills, replacement usually makes more sense. But we always give you an honest assessment first and let you decide.

Do you install ductless systems?

Yes. Ductless mini splits are a strong option for additions, older homes without ductwork, or rooms that never seem to cool evenly. We can help you decide if one is right for your situation.

Is financing available?

It is. We offer financing so you can move forward with the system you need without paying the full cost up front. Ask us about the options when you call.
