Longmont HVAC Services | High 5 Plumbing, Heating, Cooling & Electric

Reliable Heating & Cooling Services in Longmont, CO

Longmont sits along the Front Range at the base of the foothills, where a warm afternoon can turn into a cold night without much warning. That kind of temperature swing puts real pressure on a home comfort system, and when the furnace quits in January or the AC dies in July, you feel it fast.

That is where we come in. High 5 Plumbing, Heating, Cooling & Electric has been serving Denver and the surrounding communities since 2012, and our team is ready to help you at (720) 615-9621. We are licensed and insured under Colorado License #189849, and when you call, a real person answers, not a call center.

HVAC Services in Longmont, CO You Can Count On

Home comfort is not a luxury in Colorado. It is the difference between a livable house and a miserable one. And because the weather here does not keep business hours, we do not either. Our phones are staffed 24/7, so a late-night breakdown does not have to wait until morning.

The reality is that most homeowners do not think about their heating and cooling until something goes wrong. But a system that gets regular attention lasts longer, runs cheaper, and breaks down less often. Whether you need a fast repair or a full replacement, we handle it with upfront pricing, so you get the number before the work starts and never see hidden fees on the invoice.

Cooling Services

When the summer heat rolls in off the plains, a working AC is not optional. Here is what we cool your home with:

Heating Services

Front Range winters are no joke, and a dead furnace at 2 a.m. is a problem you want fixed now. We service and install the equipment that keeps you warm:

We install and service trusted brands like Rheem, Ruud, and Navien, and our technicians work on most major brands regardless of who installed the system originally.

More Than Just Another Service Call

Anybody can send a truck. But we think you deserve more than a stranger poking around your home. Every technician who shows up at your door is background-checked, so you know who you are letting inside.

That trust is not something we take for granted. We hold an A+ accreditation with the BBB and have earned more than 6,000 Google reviews from homeowners across the metro. And every job is backed by our 100% satisfaction guarantee, because we would rather do the work right than do it twice.

The catch is that quality service should not force you to drain your savings all at once. That is why we offer financing on larger projects, so a new furnace or air conditioner fits your budget instead of blowing it apart.

Even better, our Club Membership plan keeps your systems in shape year-round. Members get routine tune-ups across plumbing, HVAC, and electrical, plus priority scheduling and discounts on repairs. It is the simplest way to catch small problems before they turn into emergencies.

We Do More Than Heating and Cooling

We started as a plumbing company, and that side of the business is still going strong. If you have a leak, a clog, or an aging water heater, the same crew you trust for HVAC handles it. Here is the range of plumbing work we take on:

Frozen pipes deserve a special mention here. When temperatures drop off the foothills and stay there, exposed plumbing can freeze and burst, and the water damage that follows is far more expensive than the repair itself. If you catch a pipe before it splits, call us. And if it already has, call us faster.

How We Handle Your HVAC Services in Longmont, CO

Good service is not complicated, but it does take discipline. We answer the phone, we show up when we say we will, and we tell you the price before we lift a wrench. No surprises, no runarounds, and no pressure to buy something you do not need.

Our High 5 Cares community program keeps us connected to the neighborhoods we serve, spotlighting a local nonprofit every month. Because being a good contractor and being a good neighbor should be the same thing.
