Types of HVAC Systems We Service

Allen Service services furnaces, central air conditioners, heat pumps, ductless mini-splits, boilers, thermostats, ventilation equipment, indoor air quality systems and commercial HVAC equipment.
HVAC Problems To Look Out For
Changes in temperature, airflow, operating cycles or HVAC noise can indicate a developing equipment problem. Scheduling service when warning signs first appear may help address a smaller issue before it causes a complete heating or cooling failure.
Heating System Issues
- The furnace repeatedly shuts down before reaching the thermostat setting
- Warm air is noticeably weaker at rooms farther from the furnace
- The furnace makes a booming sound when starting
- The blower operates but little heat reaches the rooms
- Heating costs rise while the home feels less comfortable
Air Conditioning Issues
- The AC cannot keep up during hotter afternoon hours
- Cooling starts normally but stops after a short period
- Some rooms remain warm despite strong airflow elsewhere
- The outdoor unit runs while indoor air stays warm
- Water or condensation appears around the indoor cooling equipment
General HVAC Warning Signs
- The system cycles much more frequently than it used to
- Airflow changes significantly from one room to another
- New rattling, buzzing or grinding noises develop
- Unusual odors appear shortly after the system starts
- The thermostat requires frequent adjustments to maintain comfort
Local Considerations When Choosing a New HVAC System
Commerce City experiences cold winters, hot summers and substantial temperature swings throughout the year. The local housing stock also includes many newer single-family homes alongside older properties, making proper equipment sizing and evaluation of existing ductwork, insulation and electrical infrastructure important when choosing a replacement HVAC system.
Local Factors
Commerce City Data
HVAC Impact
Cold Weather Heating Demand
Winter temperatures typically fall into the low 20s, with December averaging about 46°F high / 23°F low.
Furnaces and heat pumps need sufficient heating capacity for below-freezing conditions and changing winter loads.
Summer Cooling & Humidity
July averages about 89°F high / 62°F low, and muggy conditions are uncommon.
Proper AC sizing and airflow are important during hot afternoons, while moisture removal is generally less demanding than in humid climates.
Snowfall & Outdoor Unit Exposure
Commerce City experiences snowy winters and regular freezing conditions.
Heat pump and AC outdoor units need appropriate clearance, drainage and placement to reduce obstruction from snow and ice.
Home Size & Housing Stock
Commerce City is largely a homeowner community, with about 77% owner occupancy, and detached single-family homes make up a large share of local housing.
Equipment should be sized to the individual home’s square footage, layout, insulation, windows and ductwork rather than selected by a general rule of thumb.
Home Age & Construction Mix
The city’s 2025 housing assessment identifies 2005 as the median year built for Commerce City’s overall housing stock.
Newer homes may have different efficiency and ventilation needs than older properties, while existing HVAC infrastructure still needs to be evaluated individually.
Electricity Rates & Energy Costs
Commerce City residents may receive electricity from Xcel Energy or United Power depending on location. Xcel also uses residential time-of-use pricing.
Efficiency ratings, fuel type, controls and when equipment operates can affect long-term heating and cooling costs.
Permits & Local Regulations
Commerce City uses the 2021 International Mechanical Code, and permits are required for new and replacement HVAC equipment.
New HVAC installations and qualifying replacements need to meet current local mechanical, energy and permitting requirements.

Common HVAC Questions
How often should I schedule HVAC maintenance in Commerce City?
Most homeowners should have their heating and cooling equipment serviced regularly, particularly before periods of heavy seasonal use. A heating visit before winter and cooling visit before summer can help identify developing problems before demand peaks.
How do I know when to replace my HVAC system instead of repairing it?
Consider the equipment’s age, repair frequency, efficiency, overall condition and the cost of the current repair. An HVAC technician can inspect the system and help compare continued repair with the potential benefits of replacement.
Do I need a permit to replace HVAC equipment in Commerce City?
Yes. Commerce City specifically lists new and replacement HVAC equipment among projects requiring a permit. Qualifying work must also comply with the city’s current mechanical and building codes.
