Get answers to common questions about hvac services in Longmont, Colorado.
In Longmont, a full furnace replacement typically ranges from $4,500 to $8,500+, depending on the unit's efficiency (AFUE), size (BTU output), and complexity of installation. Costs are influenced by Colorado's high-altitude requirements, which necessitate specific high-altitude kits for proper combustion and efficiency, and the type of furnace (e.g., modulating gas vs. standard). Always get multiple detailed estimates that include this critical altitude adjustment.
The optimal times are during the shoulder seasons—spring (April-May) and fall (September-October). Scheduling service before the intense summer heat or winter cold ensures your system is ready for Longmont's temperature extremes and helps you avoid the high-demand rush periods when HVAC companies are busiest and wait times are longest. This proactive timing can also prevent emergency breakdowns.
Yes. Longmont residents must comply with city codes for permits on new installations, which a reputable contractor will handle. Crucially, you should check for rebates from the City of Longmont's Utilities Department and from Xcel Energy for upgrading to high-efficiency HVAC equipment. These incentives can significantly offset the cost of qualifying ENERGY STAR® heat pumps, furnaces, and air conditioners.
Look for a licensed, insured, and locally established contractor with specific experience with high-altitude installations. Check for positive reviews on local platforms and ask for references from Longmont homeowners. A trustworthy provider will perform a detailed Manual J load calculation to right-size your equipment for our climate and will clearly explain local rebate and financing options.
Given Longmont's winter temperatures that can drop well below freezing, it's normal for your furnace to have longer run cycles on the coldest days. However, if it's constantly cycling on and off (short-cycling) or struggling to maintain temperature, it could indicate issues like a dirty filter, improper airflow, an undersized unit, or a failing component. An annual tune-up before winter is essential to ensure efficiency and reliability.
