On the heating side, we repair, maintain, and install furnaces, boilers, and heat pumps.
For cooling, we cover air conditioners and swamp coolers, from quick repairs to full installations.
We handle the full range of water heaters too, from traditional tank and tankless units to heat pump models, for both repair and installation.
We also offer Total Home Care Club membership for ongoing maintenance and WiseTack financing for larger jobs.
Prime has served the Denver metro since 2012 and completed well over 15,000 jobs. We're family-owned and operated, and Nathan Padilla, who founded the company, has been its sole owner since 2016.
Nathan started his apprenticeship in 1998 and graduated at the top of his class of 68, earned his Colorado Master Plumber license in 2007 (License #PC3045), and holds an ICC National Standard Master Mechanical certification from 2013. That's more than 27 years in the trades, and it's the same person whose name is on the company today. You can verify the plumbing license through Colorado DORA.
We cover eight cities across the metro: Denver, where our headquarters sits at 7000 Broadway Suite 205, Denver, CO 80221, plus Arvada, Aurora, Broomfield, Commerce City, Lakewood, Thornton, and Westminster. Same-day availability runs across all of them.
Heating and cooling
Most cooling and heating problems come down to a straightforward repair, and that's usually the right call. But if your system is more than 10 years old and the repairs are getting more frequent and expensive, replacement often makes more sense than pouring money into aging equipment.
The rule of thumb I use: if the repair quote runs past about half the cost of replacement, or the system is 15-plus years old and breaking down repeatedly, replacement is usually the smarter investment. Denver's hard water and big temperature swings wear hard on coils, heat exchangers, and tank water heaters, so age catches up faster here than in milder climates.
We give you an honest assessment, not a push toward the bigger ticket. Learn more on our AC repair page.
A few patterns tend to show up together: air that never quite gets cool or warm enough, strange sounds or foul odors when the system runs, short cycling where it kicks on and off too often, water pooling around the unit, and energy bills that climb higher than your neighbors' with similar homes.
The clearest sign in Denver is a system that can't keep up, struggling through 90-plus-degree summer afternoons or sub-zero winter nights. If you're seeing two or more of these, it's worth a professional look. We can usually diagnose it in a single visit.
Most tune-ups cover the same core work: replacing the air filter, cleaning the condenser and evaporator coils, clearing dirt buildup, cleaning the drain pan, checking and replacing worn parts, and testing connected components like the thermostat and ductwork.
We recommend scheduling maintenance twice a year, in spring for cooling and fall for heating. That rhythm matches Colorado's seasons and catches small problems before they turn into emergency calls. Members of our Total Home Care Club get priority scheduling and discounted repair rates. Learn more on our AC maintenance page.
SEER2 stands for Seasonal Energy Efficiency Ratio 2, the current efficiency standard for air conditioners and heat pumps. It measures cooling output against the energy used, under test conditions that reflect how equipment performs in a real home.
Colorado sits in the federal Northern region, where new residential central air conditioners have to meet a minimum of 13.4 SEER2, and heat pumps have to meet 14.3 SEER2. A higher rating costs more upfront but generally pays you back through lower energy bills, which add up when your AC runs hard for weeks at a time. We'll help you land on the right efficiency tier for your home.
I'd steer you away from it. AC and furnace work is specialized, and manufacturers, warranty companies, and insurers often require that service be done by a certified, trained professional. Colorado law and most warranties also require licensed technicians for refrigerant handling and gas line work.
The bigger issue is safety. An improper repair on an altitude-adjusted furnace, common here, can create real carbon monoxide risk. I can tell you from experience that a botched DIY almost always costs more than doing it right the first time.
Yes. Denver sits at 5,280 feet, where thinner air changes how gas appliances burn fuel. Furnaces and water heaters built and tested at sea level need to be de-rated or calibrated for altitude, or you risk incomplete combustion, carbon monoxide, and reduced output.
An uncalibrated gas appliance can run inefficiently for years, quietly costing you on every bill while producing more combustion byproducts than it should. My ICC Master Mechanical certification covers exactly this work, and we check altitude calibration on every new installation and tune-up.
Plumbing leaks and emergencies
First, find the leak and shut off the nearest water source. If you can't find a local valve, shut off the main, usually near the water meter or where the line enters the foundation. Contain the water with buckets or towels to limit damage to floors and drywall, then call a plumber who can get out fast.
For active flooding or a burst pipe, don't wait. Go straight to our emergency plumbing service.
If water is threatening your walls, flooring, furniture, or belongings, that's a job for professional help right away. A burst pipe during a hard freeze, which Denver sees regularly, sewage backing up into the home, a water heater leaking heavily, or a gas smell near a water heater or furnace all qualify.
A slow-draining sink or a slightly overflowing toilet usually isn't an emergency and can wait until normal business hours. See our emergency plumbing page for more.
Frozen pipes are one of the most common emergency calls we run during the sub-zero stretches in January and February, and a few simple habits prevent most of them. Insulate pipes in unheated spaces like crawl spaces, garages, and exterior walls. Disconnect garden hoses and shut off exterior hose bibs before the first hard freeze.
When a deep freeze hits, open the cabinet doors under kitchen and bathroom sinks so warm air reaches the pipes, and let a slow drip run on faucets along exterior walls when temperatures drop below 20 degrees. Most important, know where your main shutoff is so you can stop a burst fast.
The main line usually runs through the yard and enters the house through the concrete foundation. Most homes have a main shutoff outside and a secondary shutoff inside.
Before you touch the main, try the valve closest to the leak or clogged fixture first. In Denver metro homes, the interior shutoff is often in a utility closet near the water heater or in the basement along the front foundation wall.
Drains and sewer lines
Slow drains and sewer trouble can look alike. Here’s how to tell them apart.
For a single slow or clogged fixture, like a kitchen sink, tub, or toilet, the fix is usually straightforward drain cleaning that gets it flowing again. For grease or stubborn buildup, we use high-pressure hydro jetting to scour the pipe walls clean instead of punching a hole through the clog.
If more than one drain is acting up at once, the trouble is usually in the main line rather than a single fixture, a different fix covered in the sewer questions below. Learn more on our drain cleaning page.
The signs tend to build slowly: a persistent foul odor, more pests, mold or mildew growth, a soggy patch in the yard, a sudden spike in your water bill, or a strip of grass that's suddenly greener than everything around it.
Colorado's clay-heavy soil and freeze-thaw cycles crack older sewer lines, especially on properties built before the 1980s. The fastest way to confirm a leak without digging up the yard is a sewer camera inspection, which shows the exact location and condition of the line.
Watch for water backing up in a sink, toilet, or shower, drains that empty slowly, gurgling sounds, or problems hitting several fixtures at once.
Tree root intrusion is one of the most common causes in Denver's older neighborhoods, where mature trees sit close to original clay lines. In most cases, hydro jetting clears the roots and debris without excavation and restores full flow.
We feed a small waterproof camera through a clean-out into your sewer line, and it shows the inside of the pipe in real time: cracks, blockages, root intrusion, sagging sections, and collapsed pipe. You watch the footage with the technician and get a clear recommendation on the spot.
We'd suggest one before buying a home in Denver, especially an older home with original clay lines, after repeated slow drains or backups, if there's a sewage smell in the yard, or anytime you've been quoted a major sewer repair and want a second opinion. Results are immediate.
You're responsible for the section of sewer line that runs from your house to the city main in the street. If the break is on your property, the repair is on you, so hire a certified plumber to handle it.
If the break is in the public right-of-way or the city main itself, your local water authority handles it at no cost to you. Call us first so we can run a camera inspection and pinpoint where the break sits, on your side or the city's, before you assume the bill is yours.
Water heaters
Denver’s hard water makes a few of these answers different than elsewhere.
A tank heater stores hot water and keeps it ready. A tankless unit heats water on demand as it passes through, so it never runs out the way a tank eventually does.
In Denver's hard water, tanks pick up mineral scale faster, which shortens their life and drags down efficiency. Tankless units cost more upfront but usually last 20-plus years, compared with 10 to 15 for a tank. For repair questions on either type, see our water heater repair page.
It depends on how much hot water your household uses and what your plumbing supports. For most Denver homes with three or more people, a 50-gallon tank or a tankless unit is a sensible starting point. If efficiency is the priority, a heat pump water heater uses far less energy than a standard electric tank.
An expansion tank is often required by code when you replace one. If you're weighing repair against replacement, our water heater team will give you an honest read.
Yes, more than most homeowners realize. Denver's water carries a moderate-to-high level of hardness, so calcium and magnesium scale builds up inside pipes, water heaters, faucets, and appliances over time. That scale cuts efficiency, restricts flow, and shortens equipment life.
Hard water is one of the most underestimated causes of early water heater failure I see in Denver homes. We recommend flushing tank water heaters annually, and many homeowners benefit from a water softener or whole-house filtration to protect the whole system.
Pricing, financing, and membership
There's no flat number, and anyone who quotes one sight unseen isn't being straight with you. The cost depends on your home's size, the equipment and efficiency tier you choose, the condition of your ductwork, and whether you're replacing the AC alone or pairing it with a furnace or heat pump conversion. Colorado's minimum efficiency standard also shapes which equipment fits.
We give you an upfront price before any work starts, so there are no surprises. If paying out of pocket isn't ideal, we offer WiseTack financing with approval in minutes and no upfront expense.
Yes. We offer WiseTack financing with no upfront out-of-pocket expense and approval that usually takes a few minutes. It removes the cost barrier when you need a repair or replacement now but can't pay the full amount today.
Financing works for AC replacement, water heater replacement, sewer line repair, furnace replacement, and other larger jobs.
It's our preventive maintenance membership, built around getting ahead of problems instead of reacting to them. Membership includes scheduled seasonal tune-ups for your heating and cooling, priority scheduling when something breaks, exclusive member discounts on repairs and upgrades, and quick access to emergency help.
It's the simplest way to extend the life of your equipment, keep your bills predictable, and skip emergency-rate pricing. You also get a documented service history that helps with warranty claims and resale.
Commercial plumbing and HVAC
Yes. We serve restaurants, dental and medical offices, property managers, apartment complexes, and HOAs across the Denver metro.
