Furnace Service Frequently Asked Questions

You don’t! That is why we recommend a yearly safety inspection. Many furnaces still function even though they can be very dangerous.

You can buy a CO detector or have a furnace safety inspection performed on your unit. Many CO detectors do not detect low levels of Carbon Monoxide.

We recommend having your furnace and A/C checked every year.  You never know when a safety concern with your furnace or an efficiency concern with an A/C will arise. Properly maintained units will last longer and will also save you on costly undetected repairs or problems. It also helps maintain efficiency because unmaintained units lose 5% efficiency each year.

Most furnace filter changes require you to open a furnace cover door and access the filter. It will be accessible on the front of the furnace. Below is a helpful video to take you through a filter change step by step.


It is usually on the filter you pull out of the furnace or labeled on the duct work near the filter. Filter sizes vary greatly, and it should be easily visible since each unit is different.

Some furnaces and duct work can take a while to heat up.

That is a hard question to answer. It depends on proper equipment sizing, maintenance, and brand. In our climate, 15 years is average for a furnace and A/C. If properly maintained, a system can last as long as 20 years.

It depends upon what kind of furnace you have. Standard furnaces should be set to auto. Variable speed furnaces should be set to on. Our technicians will tell you which kind you have. The blower should be on at all times if you have indoor air quality products such as electronic air cleaners, UV lighting systems, and whole home humidifiers.

We repair all major furnace and A/C brands. If it is in your house, chances are we will work on it. We install quality American Standard products with pricing options for every budget.

If our technician diagnoses the issue and that is not the issue, you only pay for the repair that is necessary. Also, view the “No Breakdown Guarantee” below.

Furnace prices can range dramatically. For a 2500 sq. ft. home with a good warranty and city/county permits (most often skipped by most contractors), you can get a high-quality, long-lasting furnace installed for between $4k-$5k.

Common Furnace Tune-Up Scams to Watch out for

 Is it a Furnace Scam or Sales Tactic?

It usually starts off with the cheap furnace tune-up special in the dead of winter followed by a high-pressure sale.

This is the cracked heat exchanger furnace scam.

First, furnace heat exchangers do and will crack eventually, if not properly maintained or installed. It may be related to the oversizing problem from one of the earlier scams. If a technician ever says, “It’s a cracked heat exchanger. You need to immediately change your furnace. I can get started right now!” You may want to take a few steps back and get a second opinion.

First, you need to ask for visible proof that it is cracked. If they cannot provide that, chances are they are lying to you. Second, ask if your furnace is leaking any carbon monoxide. Real HVAC technicians should have combustion analyzers and ambient carbon monoxide meters on their vehicles.

Don’t be afraid to ask for proof!
Reputable companies, there are a lot of us out there, find all sorts of problems with furnaces, including cracked heat exchangers.  The difference is, reputable companies and their technicians will give you several options for repairs and replacements instead of looking for a quick high-pressure sale.

888 Heating & Air Conditioning is an awesome company. I've had them come out to do annual preventive maintenance checks on my ductless heat pump since it was installed. I have recommended them to friends and family.

888 Heating & Air Conditioning did a great job helping with our thermostat. The technician, Garen, provided great services, worked fast, cleaned up and explained everything I asked about, very professional.
Kevin M.
Excellent and informative service from Garen. He is clearly an expert and spent time explaining the differences and issues with our two heating units. We'll definitely be contacting 888 for our AC unit servicing in the spring!
Becky T.
These guys do great work and care about the results. At first the zoning was not working as well as I expected but the 888 team returned and made adjustments on several occasions. The system now works beautifully and we are very happy with the results.
