HVAC Services in Denver, CO

Call (720) 637-5157 Today. We’re Here When You Need Us.

Homes and properties go through a lot over the course of a year. Dry winters, sudden cold snaps, hot summer afternoons, and those in-between seasons where your system seems to run all in one day. That kind of climate doesn’t leave much room for guesswork when it comes to heating and cooling.

At True Heating & Cooling, we work with property owners across Denver who just want straight answers, dependable service, and systems that keep up with the pace of daily life. Whether it’s a furnace that won’t kick on, an AC that’s struggling by mid-afternoon, or a system that’s simply getting older, we’re here to help you figure out what makes sense and move forward from there.

A Local HVAC Company That Knows Denver 

We have been working throughout the Denver metro area since 2015. We are familiar with the specific challenges of our region, from older homes with aging ductwork to newer builds featuring high-efficiency systems.

Every property has a unique setup, and we approach each one individually. Some calls are straightforward mechanical fixes, while others turn into conversations about airflow issues or indoor air quality. We take the time to look at the full picture so you aren’t left dealing with the same recurring issue a few months down the line. Our team consists of licensed, NATE-certified technicians who stay current with the latest equipment. As an official Lennox dealer, we also provide access to reliable, modern options when it is time for a replacement.

How We Approach Each Service Call

Many of our clients have had the experience of calling a service company and feeling rushed into a big purchase. That isn’t how we operate. When we arrive, we explain what we see in plain terms. If it’s a simple fix, we’ll say so. If there are multiple paths forward, we walk you through each one so you can decide what fits your budget. We keep pricing clear and upfront, with no surprises halfway through the job.

When It’s Time to Call Us

Not every issue starts with a full breakdown. 

It is often better to catch things early if you notice:

• Rooms that feel warmer or colder than others.
• Higher-than-usual energy bills.
• Strange noises or odors coming from the vents.
• Frequent cycling or trouble maintaining a set temperature.
• Older equipment that hasn't been checked in a while.

Comprehensive Heating & Cooling Services

AC Repair, Installation & Replacement

When summer hits, a working air conditioner is a necessity. If your system is blowing warm air, short-cycling, or struggling to keep up with the thermometer, we will take a look and walk you through the cause. If repairs are the practical choice, we handle them efficiently; if your system is reaching the end of its life, we’ll discuss replacement options without any pressure.

Furnace & Heating Services

Cold mornings aren’t something you want to face without a working heater. We service and install furnaces, boilers, and heat pumps. If your system has been making unusual noises, cycling unevenly, or driving up your energy bills, it is worth having it checked before the next cold front rolls through.

Heat Pumps & Ductless Systems

Many local homeowners are looking into heat pumps and ductless mini-split systems for additions, older homes, or rooms that never quite stay comfortable. We install and service both, and we can help you decide if they make sense for your space based on how you actually use your home.

Indoor Air Quality & Humidity

Our dry climate can be tough on indoor comfort. Dry air and dust buildup are common concerns we hear about in the Front Range. We install humidifiers and air filtration systems that balance your indoor environment and make your home feel better day-to-day.

Ductwork, Thermostats & System Tune-Ups

Sometimes the issue isn’t the equipment itself, but how the air moves or how the system is controlled. We handle ductwork adjustments, smart thermostat installations, and seasonal maintenance to help keep everything running as intended.

How To Really Maintain a System

Maintenance isn't just a checklist; it's about preventing the "big" breakdown when you least expect it. In Denver, your system works twice as hard because of the drastic temperature swings. 

The most effective way to keep things running is consistency, focusing on a few key habits:

• Swap your filters every 30 to 90 days. This is especially important in Colorado during high-pollen springs or those late-summer smoke seasons.
• Keep leaves, tall grass, and cottonwood seeds away from your outdoor unit. Your system needs to "breathe" to move heat effectively.
• Professional eyes-on inspections. A deep-dive check once or twice a year allows us to catch worn belts, electrical wear, or small refrigerant leaks before they turn into a mid-winter emergency.
• Listen for changes. If your system starts making new sounds or the cycles feel longer than usual, it’s usually telling you something is out of alignment.

A well-maintained system doesn’t just last longer; it runs quieter and keeps your monthly utility bills far more predictable.

Working With True Heating & Cooling

We have built our reputation around straightforward service and consistent results. There are no shortcuts or overcomplicating the job here. Our goal is simple: help you keep your home comfortable with a system that works the way it should, making the process as stress-free as possible.

If you’re dealing with a heating or cooling issue or you’re thinking about upgrading your system, we’re ready to help. Call (720) 637-5157 or contact us online to schedule a service.
