How often should I have my air conditioner serviced?

We recommend having your air conditioner serviced annually, preferably before the start of the cooling season. This helps ensure that your system is running efficiently and can prevent potential breakdowns during the hot summer months.

What are some signs that my furnace needs repair?

Some common signs that your furnace may need repair include unusual noises, uneven heating, frequent cycling on and off, and higher-than-normal energy bills. If you notice any of these issues, contact UniColorado for prompt furnace repair services in Centennial.

How can I improve my home's indoor air quality?

Key steps include regular filter changes, annual HVAC maintenance, and maintaining 30-50% humidity (especially important in Colorado's dry climate). We install electronic air cleaners and whole-home humidifiers to address Centennial's typical indoor air quality challenges.

What are the benefits of installing a heat pump in my Centennial home?

Heat pumps are an energy-efficient alternative to traditional heating and cooling systems, as they can both heat and cool your home. Newer heat pump models (often referred to as cold climate heat pumps) are particularly effective in colder climates like Centennial, as they can provide reliable comfort year-round while helping to reduce your energy costs.

How long does a typical AC installation take?

The duration of an AC installation can vary depending on the complexity of the job and the size of your home. However, most installations can be completed within the same day. Our team at UniColorado will provide you with a detailed timeline and keep you informed throughout the installation process.

How do I know if my Centennial home's ductwork needs modification?

Many 1970s-1980s Centennial homes have undersized ductwork for modern high-efficiency systems. Signs include uneven temperatures between rooms, weak airflow from vents, or excessive noise. We assess ductwork during every estimate and include modifications in the quote when needed.

Local HVACConsiderations

HVAC Engineering for the South Suburbs

5,830 ft elevation

Curing the 'Hot Upstairs, Cold Downstairs' Problem: Centennial's abundant split-level and large two-story homes suffer from massive thermal stratification. We solve this by installing variable-speed air handlers (like the Carrier Infinity system) that continuously mix the air, paired with smart zoning dampers.
Ductwork Undersizing Epidemic: Homes built in Centennial during the 70s and 80s were piped for standard 80% efficiency furnaces. Modern 96%+ efficiency equipment requires significantly more airflow. We rigorously measure your static pressure and resize return drops or add supplementary returns to prevent your new system from suffocating.
Combating Extreme Winter Dryness: Our 5,830-foot elevation means winter air here holds almost zero moisture. To protect your hardwood floors, prevent static shock, and make 68°F feel warm, we strongly recommend integrating an AprilAire or steam humidifier directly into your new furnace.
The Payback on High-Efficiency Upgrades: Because older Centennial homes are often running on original, 30+ year-old 70% AFUE furnaces, upgrading to a 96% modulating furnace or a Bosch cold-climate heat pump offers one of the fastest utility bill paybacks in the state.

Altitude Impact

At 5,830 ft, air conditioning systems derate approximately 12% compared to sea-level ratings. We account for this in every system design.

Centennial Housing

The bulk of Centennial's housing boom occurred between the late 1970s and 1990s. Neighborhoods like Willow Creek and Foxfield are dominated by classic bi-level, tri-level, and sprawling two-story floor plans. These layouts are notorious for extreme temperature stratification—freezing basements and boiling upper floors—which requires specialized variable-speed blowers and strategic zoning to correct.

Local Climate

At 5,830 feet, Centennial is one of the highest-elevation major suburbs in the metro area, sitting 500 feet higher than Denver. This intense elevation heavily derates gas furnace combustion by up to 18%, meaning an 80K BTU furnace only produces 65K BTUs of actual heat. Additionally, the Cherry Creek corridor creates unique microclimates that trap cold air pools, increasing baseline heating loads for nearby neighborhoods.

Local History

The Story of Centennial

Centennial, a suburb located within the Denver metro area, has a recent and modern history. Just over 20 years old, Centennial was incorporated in 2001 after citizens voted to incorporate it just one year earlier. The town's name is a nod to Colorado's incorporation as the 38th state in 1876 and the centennial year of the United States Declaration of Independence. Spread across 19,115 acres, including 94 acres of water, Centennial is defined by a multitude of hills, gullies, ravines, and open spaces that are accompanied by recreational trails and parks. Centennial is home to the second largest IKEA in the US, the Denver Broncos state-of-the-art training center, Centennial Center Park, and is ranked as one of the United States' safest communities since its incorporation.
