What's Going On?

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
