Tell us the symptom, we'll tell you what it means and what it needs.
AC not blowing cold air?
Could be low refrigerant, a dirty coil, or a failing capacitor - and the fix ranges from a $20 filter to a real repair. Show us over video and we'll tell you which one you're dealing with.
Get my diagnosis →AC running constantly but not cooling?
Usually means the system is struggling, not just adjusting. Low refrigerant and a failing compressor both look like this from the outside - we'll help tell them apart.
Get my diagnosis →Furnace not turning on?
Start with the thermostat and breaker. If those check out, it's likely the igniter or a safety switch. We'll walk through it with you on video before you call anyone.
Get my diagnosis →Furnace won't ignite?
Often a failed igniter or flame sensor - a relatively small part, but not a safe DIY job on a gas system. Show us what's happening and we'll tell you what it needs.
Get my diagnosis →Furnace making a strange noise?
Banging, screeching, or rattling all point to different problems - loose panels, a worn blower belt, or something more serious. We'll help you figure out which before it gets worse.
Get my diagnosis →Thermostat not working or blank?
Sometimes it's dead batteries. Sometimes it's a tripped breaker or a wiring issue behind the wall. We'll help you rule out the easy fix first.
Get my diagnosis →Heat pump not heating?
Could be stuck in the wrong mode, low on refrigerant, or icing over. Heat pumps are more specialized than standard furnaces - show us what's going on before you pay for a guess.
Get my diagnosis →My AC just isn't cooling?
The most common HVAC complaint, and one of the widest in cause - from a dirty filter to a dying compressor. A quick video look narrows it down fast.
Get my diagnosis →What Should It Cost?
National averages, so you're not guessing. Your exact number depends on where you live and what's actually wrong - that's what your Chilll estimate gives you.
Furnace repair cost
Nationally runs $150–$600, averaging around $350. Major parts like a heat exchanger or blower motor push it higher. We'll tell you which tier you're in.
AC repair cost
Typically $150–$600 nationally, averaging around $350. A simple capacitor swap sits at the low end; a compressor failure sits well above it.
Thermostat replacement cost
Usually $150–$400 installed nationally. Smart thermostats and extra wiring work can push it higher - we'll tell you what your setup actually needs.
AC replacement cost
A full central AC replacement nationally runs $3,000–$7,500. Before you get quoted for this, make sure repair is actually off the table - we'll tell you honestly if it is.
Ductwork repair cost
Minor duct repairs typically run $200–$700 nationally. Full replacement costs considerably more - most duct problems don't require it.
Cost ranges above are 2026 national averages, sourced from Angi and HomeAdvisor cost guides. Actual pricing varies by region and the specific problem - Chilll's video estimate gives you a number for your actual home.
Fix It Yourself, or Call a Pro?
We don't make more money by telling you to hire someone. So we won't, unless you actually need to.
Should I fix my own furnace?
A dirty filter or a tripped breaker: fair game to check yourself. Anything involving gas, the igniter, or the heat exchanger: not a DIY job. We'll tell you honestly which one you're facing.
Ask us first →DIY AC repair vs. professional?
Cleaning coils and swapping a filter, sure. Refrigerant and electrical work needs a licensed pro, both for safety and because refrigerant handling is federally regulated. We'll walk you through where the line is.
Ask us first →When should I call an HVAC professional?
Any gas smell, burning smell, or repeated breaker trips - call immediately, don't wait. For everything else, show us first so you know if it's urgent or if it can wait for a scheduled visit.
Ask us first →Is it safe to replace a thermostat myself?
Often yes, for a simple swap with the same wiring setup. Smart thermostats needing a C-wire, or homes with older systems, are where it gets trickier. We'll tell you which situation you're in.
