What Longmont Property Owners Should Know About Furnace Repair and Replacement
Humidity and Your AC in Longmont
In Longmont's climate, an AC does two jobs: cooling and pulling humidity out of the air. An oversized or short-cycling unit cools fast but leaves the home damp and clammy. HVACPros Heating and Cooling checks that your system actually controls humidity, not just temperature.
Right-Sizing Your System in Longmont
Bigger is not better with AC. An oversized unit short-cycles, wears out faster, and never dehumidifies properly; an undersized one runs nonstop. Before any replacement, HVACPros Heating and Cooling runs a load calculation for your Longmont home so the system is matched to it.
Refrigerant Type in Longmont Homes
Older systems in Longmont may still run on phased-out R-22, which is expensive and getting scarce. HVACPros Heating and Cooling tells you honestly whether topping off an older unit makes sense or whether moving to a current refrigerant (R-410A / R-454B) is the smarter spend.
Before You Hire: Furnace Repair and Replacement in Longmont Checklist
- ✓Verify the company carries liability insurance and workers' compensation coverage in CO
- ✓Ask for a written estimate with itemized costs before authorizing any work
- ✓Check their Google reviews — look for specific, detailed reviews from Longmont customers
- ✓Confirm they handle CO permits and inspections when required
- ✓Ask about their warranty and what happens if you're not satisfied
- ✓Request references from recent Furnace Repair and Replacement projects in Longmont
HVACPros Heating and Cooling meets every item on this checklist. Call (983) 221-1905 to verify or ask us anything.

Carbon Monoxide Safety
The CDC reports 400+ deaths annually from unintentional CO poisoning. Older Longmont homes with gas furnaces need annual safety inspections. Our HVAC professionals check for CO leaks, cracked heat exchangers, and gas line integrity.
Energy Efficiency Savings
Homes in Longmont can save 20-40% on energy bills with properly maintained HVAC systems. According to the U.S. Department of Energy, heating and cooling accounts for 48% of a typical home's energy use. Our technicians optimize your system for CO's specific climate demands.
24/7 Emergency HVAC Service

Local Code Compliance
Building codes in Longmont, CO require specific HVAC installation standards including ductwork sizing, refrigerant handling, and electrical connections. We ensure every job passes local inspection.
Indoor Air Quality Improvement

4 Signs Your Longmont Home Needs HVAC Repair or Replacement
Don't ignore these common indicators — early action prevents costly damage and saves money.
Unusual Noises from Your HVAC System
Banging, squealing, or rattling from your HVAC unit often indicates loose components, worn bearings, or failing motors. The Dept. of Energy notes that ignoring these sounds can reduce system efficiency by 10-25% and lead to complete failure.
Sudden Spike in Energy Bills
A sudden increase in heating or cooling costs of 15%+ without usage changes typically means your HVAC system is working harder due to a developing mechanical or airflow problem.
Weak or No Airflow from Vents
Reduced airflow can indicate a failing blower motor, clogged filters, or ductwork collapse. Restricted airflow forces the system to work 25-50% harder, increasing energy costs and wear.
Excessive Indoor Humidity
Your HVAC system should maintain 30-50% relative humidity. If your home feels muggy in summer or excessively dry in winter, the system's dehumidification or humidification function is failing.

What Longmont Homeowners Ask About Furnace Repair and Replacement
How much does HVAC service typically cost in Longmont?
HVAC service costs in Longmont depend on the type of work. A standard tune-up runs $75-$150, while common repairs range from $150-$800. Full system replacements typically cost $5,000-$15,000 depending on system size (measured in tons) and efficiency rating (SEER). Higher-SEER systems cost more upfront but reduce energy bills by 20-40% annually. HVACPros Heating and Cooling provides free written estimates with itemized breakdowns so you can compare options.
How often should I schedule HVAC maintenance in Longmont?
The industry standard is twice per year — once for heating (fall) and once for cooling (spring). Regular maintenance improves efficiency by 15-20%, extends system life by 5-10 years, and prevents 95% of breakdowns according to ACCA data. For Longmont homes with pets, allergies, or older systems, quarterly filter changes are also recommended. HVACPros Heating and Cooling offers maintenance agreements that include priority scheduling and discounted rates.
What size HVAC system does my Longmont home need?
System sizing requires a Manual J load calculation based on your home's square footage, insulation levels, window area, ceiling height, and orientation. A rule of thumb is 1 ton per 400-600 sq ft, but this varies significantly — an undersized system runs constantly and an oversized system short-cycles, both wasting energy and money. HVACPros Heating and Cooling performs proper load calculations for every installation in Longmont to ensure correct sizing.
