Denver Home Services

Heating, Cooling, Plumbing & Electrical From a Single Trusted Team

When your furnace quits on a January night or your AC fails during a Denver heat wave, the last thing you need is to call three different contractors and hope one shows up. Allen Service has handled heating, cooling, plumbing, electrical, sewer and drain, and restoration for Denver-area homeowners since 1962. Third-generation brothers Jeff and Mike Allen lead the company today under the same motto their family built it on: “The name you know and trust.” Allen Service works with Service Financing for all your HVAC and home service financing needs.

One Call For It All™

Home maintenance is simpler when one team handles everything. Instead of juggling multiple contractors, you only need our number; we cover HVAC, plumbing, electrical, and restoration under one roof. Our technicians are trained across disciplines, which means they can spot connected issues that single-trade contractors often miss. We also maintain a shared service history for your home, so every visit builds on what we already know. That matters most when multiple problems hit at once. One call to Allen Service covers all of it.

Thanks Allen! You guys are GREAT!
“My technician today was professional, courteous, thorough, and made everything easy to understand. My AC had stopped working and Allen was able to get someone to my house within 4 hours which was exceptional and appreciated!”

Heating, Cooling, Plumbing, Electrical & Restoration for Denver Homes

Allen Service handles every essential home system: heating, cooling, plumbing, electrical, sewer and drain, and restoration, for Denver-area homes and businesses. That single-team model matters most when a problem crosses system boundaries. A pipe failure that soaks a wall can involve your HVAC ductwork, your electrical, and your structure within hours. We coordinate across all of it without requiring you to manage separate contractors on separate schedules.

Emergency HVAC Service in Denver Since 1962

For over six decades, Colorado homeowners have counted on Allen Service when heating or cooling systems fail at the worst possible times. HVAC emergencies tend to happen on the coldest nights and hottest days, when systems are working hardest and other contractors may be least available. Our emergency response team is available 24/7 and arrives with the parts and knowledge needed to address your comfort issue. Same-day service is available for urgent calls across the Denver metro, including Aurora, Commerce City, and the broader Front Range.

Restoration Services for Denver Homes & Businesses

Our restoration services cover water damage cleanup, fire damage cleanup and repair, mold inspections, mold removal, and sewage cleanup. Few Denver HVAC and plumbing providers offer restoration in-house. When damage is done and repairs need to start immediately, having one company that handles both the failed system and the resulting damage can make a real difference in how quickly your home can return to normal. Commercial service is available in addition to residential.

Plumber Services for Denver Homes

Water problems don’t wait for a convenient time, which is why our plumber team responds quickly to everything from small drips to major pipe bursts. We arrive ready to resolve most issues on the first visit with fully stocked service vehicles. From toilet backups to water heater failures, our technicians handle each job carefully to help prevent future complications.

Many Denver homes built before 1980 have galvanized or aging copper plumbing prone to corrosion and reduced water flow. Our team is experienced with these older systems and can assess whether targeted repairs or proactive repiping makes more sense for your home. Plumbing remodel services for kitchens and bathrooms are also available, and we use protective coverings throughout every job to keep your home clean.

Drainage Service to Protect Your Property

Blocked drains and sewer line problems can cause expensive damage quickly. Our drainage service team uses video pipeline inspection equipment to pinpoint blockage locations and sewer line conditions without guesswork. Tree root intrusion is a common issue in established Denver neighborhoods with mature landscaping. Video inspection lets us diagnose it precisely without destructive digging.

For stubborn blockages and buildup, we offer hydro jetting for thorough pipe cleaning and trenchless sewer repair for line damage that would otherwise require significant excavation. For homes with recurring drainage problems, we identify and address root causes rather than offering temporary fixes. Maintenance programs are available to keep your drains and sewer lines flowing freely year-round.

  • A plumbing emergency typically involves situations that threaten your property with water damage or create health hazards. These include burst pipes, major leaks that can't be stopped by shutting off a local valve, sewage backups, complete drain blockages causing overflow, and no water throughout your entire house. If you're unsure, call us—we can help determine if you need immediate service.
  • Due to the after-hours nature of the work, emergency plumbing service in Denver typically costs more than regular business-hour appointments. Exact pricing depends on the specific problem, necessary repairs, and the time required to fix it. Allen Service always provides upfront pricing before beginning work, so you'll know exactly what to expect. We never surprise customers with hidden fees or charges.
  • No, you should not call 911 for plumbing emergencies. Emergency services should only be contacted if there's an immediate threat to life or safety. For plumbing emergencies, call a professional emergency plumber like Allen Service directly. However, if your plumbing issue has caused a dangerous electrical situation or if gas leaks are involved, evacuate the home and call 911 first, then contact us.
  • Act quickly to minimize damage when facing a water emergency in your Denver home. First, locate and turn off your main water valve (usually near your water meter or where the water line enters your home). Move valuable items away from water if it is safe to do so. For localized issues like an overflowing toilet, close the fixture's shutoff valve instead. Soak up standing water with towels or mops to prevent further damage. Take photos for insurance purposes if needed.
  • Denver's climate creates unique plumbing emergencies. Winter brings frozen and burst pipes during cold snaps. Spring snowmelt often causes sewer backups as the ground becomes saturated. Water heater failures spike in winter when units work harder. Other common emergencies include water line breaks, major toilet clogs causing floods, and sump pump failures during summer storms. All require immediate attention to prevent costly water damage.
