Furnace Maintenance in Denver, CO
Unfortunately, many HVAC companies in Denver rush through maintenance visits, spending as little as 20-30 minutes on the job. At Fix-It 24/7, we take a different approach. Our deep clean service takes up to two hours, ensuring every part of your system is properly inspected and cleaned. And unlike other companies that skip over crucial steps or charge outrageous fees, we always pull and clean the blower wheel—a step that most companies charge $600 to $1,000 for.

- Inefficient heating

To get the most out of your heating and cooling system, you should schedule maintenance at the right time of year.
- Air conditioning maintenance should ideally be performed in the spring, before summer’s heat puts stress on your system. This ensures your AC is clean, running efficiently, and ready to handle the hottest days without unexpected breakdowns.
- Furnace or heating system maintenance should be scheduled in the fall, before the temperatures drop. A properly maintained heating system will run smoothly, keeping your home warm without overworking itself or leading to costly repairs in the middle of winter.
By staying ahead of the seasons, you avoid emergency repairs and ensure your system is operating at peak efficiency when you need it most.

- Shortened system lifespan, costing you thousands in premature replacements
- Poor indoor air quality, aggravating allergies and respiratory issues

The Fix-It 24/7 Difference: No Shortcuts, Just Quality HVAC Maintenance
Most HVAC companies in Denver, Highlands Ranch, Aurora, Littleton, and Golden perform a basic tune-up—a quick spray-down of your outdoor unit and a filter change—then call it a day. Their goal is often to find something “wrong” so they can upsell you on an expensive repair.
At Fix-It 24/7, we believe in preventative maintenance—if we do our job right, we save you money in the long run. That’s why we invest up to two hours cleaning and servicing every single component, including:
- Pulling and cleaning the blower wheel – Most companies don’t do this at all or charge $600 to $1,000 for it. We include it.
- Deep cleaning evaporator and condenser coils – Preventing overheating and improving energy efficiency.
- Inspecting and tightening all electrical connections – Reducing fire hazards and system malfunctions.
- Clearing and flushing drain lines – Preventing water damage and mold growth.
- Testing system performance – Ensuring your HVAC system is running at peak capacity.
We don’t believe in cutting corners. We believe in real service that brings value and peace of mind. This commitment is how we’ve built lifelong relationships with customers throughout the Denver metro area.
Broken HVAC System, We Know the Cause
Think the dust in your HVAC system is just dirt? Think again. Your blower wheel and air ducts are collecting:
- Human skin cells – You and your family shed millions of skin cells daily.
- Pet dander – Even if you don’t have pets, previous homeowners might have.
- Dust mite feces – Yes, bug poop! Dust mites thrive in dirty HVAC systems.
- Mold spores and bacteria – A dirty system is a breeding ground for airborne contaminants.
- Construction dust – If your home has been remodeled, fine dust from drywall and wood particles could still be circulating.
If you just moved into a home in Denver and haven’t had an HVAC deep clean, you’re breathing in the last owner’s dust and skin cells every time your system runs. Regular maintenance eliminates these contaminants and improves your home’s air quality.
Signs Your HVAC Needs Maintenance
If your HVAC system is struggling, it’s time for a professional tune-up. Look out for these warning signs:
- Uneven heating or cooling – Some rooms are too hot or too cold.
- Rising energy bills – Your system is working harder than necessary.
- Weak airflow – A clogged blower wheel or dirty air filter is restricting airflow.
- Strange noises – Rattling, banging, or squealing could indicate worn-out parts.
- Excess dust in your home – Your HVAC system is struggling to filter the air properly.
- Unpleasant odors – Musty or burning smells could signal mold or electrical issues.
