# HVAC Boulder pro > We are here to do better ## Posts - [Winter Heating Rebates and Credits in Boulder: What Ended and What Is Still There](https://boulderhvacpros.com/boulder-heating-rebates/): The federal tax credit that paid up to $2,000 toward a heat pump is gone — it applies only to equipment placed in service before 31 December 2025, with no grandfather. What remains in Boulder is utility rebates from Xcel Energy and an income-qualified county programme, both with hard deadlines. All figures on this page […] - [Furnace Won't Ignite: The Diagnostic Sequence, and Where a Homeowner Stops](https://boulderhvacpros.com/furnace-wont-ignite/): A furnace that will not ignite has stopped at one specific point in a fixed sequence, and which point it is tells you almost everything. Does the inducer run? Does the igniter glow? Does the burner light and then die after a few seconds? Those three questions separate most ignition faults from each other. Why […] - [Furnace Short Cycling: The Causes, in the Order to Check Them](https://boulderhvacpros.com/furnace-short-cycling/): Short cycling is a furnace starting, running a few minutes, shutting down before the house reaches temperature, then starting again. Start with airflow, not the thermostat: restricted airflow overheats the furnace and trips its limit switch, and the filter takes a minute to check. What short cycling actually is A furnace shutting off before the […] - [Furnace Won't Turn On: What To Check Before Calling](https://boulderhvacpros.com/furnace-wont-turn-on/): Check the thermostat and the filter first — both take minutes and need no tools. Then read the error code on the control board if it can be seen through the blower door window. The power switch, the breaker and the blower door are for the technician. If the furnace only runs after you cut […] - [Furnace Blowing Cold Air: The Diagnostic Order](https://boulderhvacpros.com/furnace-blowing-cold-air/): A furnace blowing cold air can be a thermostat setting rather than a broken part. Check the fan setting first, because it takes seconds; then the filter, because it takes a minute; then whether the furnace is shutting down on a safety device. Working in that order tells you within a few minutes whether this […] - [Carbon Monoxide: What To Do When the Alarm Sounds](https://boulderhvacpros.com/carbon-monoxide-alarm-what-to-do/): If a carbon monoxide alarm is sounding right now: get everyone out of the building and call emergency services. Do not look for the source. Do not open windows first. Do not check whether it might be the battery. Move to fresh air outdoors, account for everyone who was inside, and call from outside. That […] - [Your Furnace's Safety Switches: What They Do, and Why Making One Stop Tripping Is the Wrong Goal](https://boulderhvacpros.com/furnace-high-limit-switch/): A furnace that shuts itself off can be a safety device doing its job. The switch is not the fault — it is the report of a fault somewhere else, and restricted airflow is the first thing to check. Stopping the switch from tripping without finding what triggered it removes the protection and leaves the […] - [Winter Heating in Boulder: Gas Furnaces, Heat Pumps, and What Actually Goes Wrong](https://boulderhvacpros.com/winter-heating-boulder-guide/): Boulder homes are heated three different ways, and each one fails differently in January. About seven in ten run on natural gas, roughly one in four on electricity, and a growing number on a heat pump with a backup that most owners have never had explained to them. This guide covers all three, what breaks, […] - [Winter Comfort, Safety and Heating Costs in Boulder](https://boulderhvacpros.com/winter-heating-costs-safety-boulder/): A Boulder winter bill is driven by three things: how much backup heat your system runs, what your thermostat is actually set to do, and how much heat the building loses. This guide covers what moves the number, which situations are genuine emergencies, and what incentives still exist for 2026–27. Why a Boulder winter costs […] - [AC Blowing Warm Air in Boulder? 7 Causes & What to Check First](https://boulderhvacpros.com/ac-blowing-warm-air-boulder-causes-what-to-check-first/): If your AC is running but blowing warm air, the most common culprits are a dirty air filter, low refrigerant, or a frozen evaporator coil and two of those three you can check yourself in under five minutes. The other five causes on this list require a licensed HVAC technician, but knowing which one you’re […] - [AC Repair vs Replacement in Boulder CO: How to Decide in 2026](https://boulderhvacpros.com/ac-repair-vs-replacement-boulder-co-2026/): Here’s the short answer: if your AC is under 10 years old and the repair costs less than $500, fix it. If it’s over 12 years old and you’re looking at a $1,000+ repair, start pricing replacements. Everything in between is where the real decision-making happens and that’s what this guide is for. We’ve walked […] - [AC Maintenance in Boulder CO: Avoid Costly Summer Repairs](https://boulderhvacpros.com/ac-maintenance-boulder-co-avoid-costly-summer-repairs/): The best way to avoid a $900 AC repair in July is a $120 tune-up in April.

The systems that fail on the hottest week of the summer are almost always the […] - [Emergency AC Repair in Boulder CO: 24-Hour Service](https://boulderhvacpros.com/emergency-ac-repair-boulder-co-24-hour-same-day-service/): We offer emergency and after-hours AC repair across Boulder, CO, and the surrounding Front Range.

(2026 Pricing Guide)](https://boulderhvacpros.com/how-much-does-ac-repair-cost-in-boulder-co-2026-pricing-guide/): Most AC repairs in Boulder CO cost between $150 and $900 for common issues.

On the high end, compressor replacement hits $1,200–$2,500 and at that point, replacement often makes more financial sense than repair. Those […] - [AC Repair in Boulder CO: Complete 2026 Homeowner's Guide](https://boulderhvacpros.com/ac-repair-in-boulder-co-complete-2026-homeowners-guide/): When your AC stops working in Boulder, you feel it fast.
