Every HVAC company puts the same things on a van and the same words on a website. Customer reviews are the one place where you can find out how a company behaves when something goes wrong, when a quote turns out to be wrong, or when a homeowner has a question six months after the job.
Here is how to read them, what to ask for afterwards, and the red flags worth walking away from.
What should you look for in customer reviews?
Read the detailed reviews, not only the rating. Seven patterns tell you the most about any contractor.
- How they explain the problem. Reviews that mention a clear explanation of the fault are the most useful signal you will find.
- Whether the price was explained first. Look for comments about being told the cost before the work started, and about no surprises on the invoice.
- How they handle a problem after the job. A company that comes back and fixes its own work without an argument is worth a lot more than one with a higher score and no aftercare.
- Whether the same complaint appears again and again. No business is perfect, but a repeated complaint about communication or punctuality is a pattern, not bad luck.
- Whether the technician was tidy and respectful. People mention matting, shoe covers and being told what was going to happen before it happened.
- How they handle a difficult job. Reviews that describe a tricky repair or an unusual install tell you more about skill than a review of a filter change.
- Whether the warranty was honoured. If a customer came back under a warranty, how the company responded is the most revealing review on the page.
Here is what that looks like in real Google reviews of our work.
Very punctual professional and honest company. shekhar prabhakar, Google review
They went out of the way to keep me informed along the way. I highly recommend this company for their honesty and integrity. russell thomas, Google review
Quick and fast service, price is very reasonable and job was done great. Vaneet Kahlon, Google review
Those three comments cover the three things worth checking: honest communication, a price that was reasonable, and people who turned up when they said they would.
What to check on the written quote
A quote is where a good contractor shows their working. Before you sign anything, check these six things.
| Check this | What a good quote says |
|---|---|
| Total price | Labour and parts together, with the price still valid if the job takes longer |
| What is being done | The fault, the repair or replacement, and why that option |
| Warranty | How long the workmanship is covered and what is excluded |
| Payment terms | When payment is due and what the payment method is |
| License number | The California license number on the document |
| What happens if it gets worse | Who to call and what the next visit costs |
Questions to ask before you book
- What exactly is wrong, and how do you know? The answer should be a diagnosis, not a guess. If they cannot tell you what failed and why, ask what they will do to find out.
- What does the repair cost, and what does the alternative cost? A good contractor will lay out the repair option and the replacement option with numbers for each.
- What is covered by the warranty? Parts, labour, and how long each lasts.
- Is the pricing transparent and provided in writing? Ours is provided upfront in writing before work starts.
- Who will be doing the work and what are they licensed for? Ask for the license number of the company that will be on your invoice.
Red flags that should make you call the next contractor
- A price that only exists on the day of the visit, with nothing written down.
- Work that starts before you have agreed a price in writing.
- A recommendation to replace a whole system based on a two minute look at a furnace.
- No license number anywhere on the paperwork, the invoice or the vehicle.
- A technician who cannot explain the fault in a sentence, or who will not answer a question about the warranty.
- Pressure to sign on the spot, or a quote that is only valid if you decide today.
Any of these is a reason to slow down. A well run company has nothing to hide and nothing to rush you into.
When to stop and call a licensed technician
Choosing carefully matters, but so does knowing when the job is beyond a homeowner. Whatever company you hire, call a licensed HVAC technician rather than attempting the repair yourself if you notice any of these.
- Any work on a refrigerant line, which has to be recovered and handled by a certified technician.
- Anything inside an electrical panel beyond resetting a breaker.
- Gas appliance work of any kind, including a pilot light that will not stay lit.
- A blower motor, a compressor or a heat exchanger, which are not DIY components.
- Water or a burning smell, which mean the system should be switched off, not adjusted.
