Heating and Air Conditioning Maintenance and Repair Services

Emergency Service

Valiant Air Solutions is there for you when you need us most.

Heating and air systems do not wait to fail when it’s convenient. In the cool of winter or the heat of summer, our experts are here to make sure your home or office is comfortable.

In any HVAC emergency, our team is ready to quickly respond and resolve your heating or air problem quickly and efficiently.

In an emergency service visit, we will diagnose the problem and review your repair or replacement options. Once a solution is found + chosen, we’ll have your system up and running before you know it!

Custom HVAC System Installations

Improperly installed HVAC systems can lead to malfunctions. Drops in energy efficiency, loud operation, or inefficient heating and cooling can all be caused by poor installation.

Our technicians at Valiant Air Solutions are experts at their craft. No job is too big, if you have a unique home or project - we can determine the right custom solution!

Heating and Cooling Repair

When your heating and cooling system needs repair, it most likely needs to be done right away. Waiting for your heater to be repaired in the winter is not only uncomfortable for your family but puts your house at risk for other issues such as frozen pipes.

We stand behind our repair services, so the next time your HVAC system is repaired - you know it will last.

Our experienced technicians are expertly trained, licensed, and certified to ensure your heating and air conditioning needs are met.

Routine HVAC Maintenance

Routine maintenance is crucial to make sure your HVAC system will last. Repairs and replacements will be less frequent with yearly inspections/checkups. A costly replacement can be avoided by catching any system error early.

In Denver county, it’s likely that your HVAC system is working hard to keep your environment comfortable in the harsh winter months and will inevitably need some work.

To get the most out of your HVAC system, be sure to set up a routine maintenance schedule. If you’re unsure of how frequent you need to have your system checked - give us a call and we can recommend services needed.

Valiant Air Solutions will make sure that your HVAC system is in top shape all year long. With yearly maintenance you can look forward to:


With consistent check-ups, you’re unlikely to have to go without heating or air. You can sleep peacefully knowing that you won’t be waking up in the middle of the night with no AC.

Your HVAC system will last longer with good maintenance. Newer models are designed to last for over 10 years when they are taken care of.


Dust and debris cause your HVAC equipment to work harder, which in turn reduces its energy efficiency and costs you more money.

Checking and replacing your filter regularly is a simple step you can take in between maintenance visits.


Scheduled maintenance = a longer lifespan. Investing in routine HVAC check-ups will ensure the health of your heating and cooling system. You can avoid large setbacks or expensive repairs when problems are caught early.
