They are thorough, kind, communicate clearly, and leave no question unanswered. Additionally, pricing is very affordable; even when I called for an emergency when my AC went out in the middle of the summer! Calling to schedule service is quick and there is always a welcoming voice on the other end. CNO is the only company I entrust my cooling and heating needs to.

Frequently Asked Questions About C-N-O Comfort Zone Heating & Cooling
How often do I need to change my air filters?
Quarterly is the best practice. More often if you have fury pets or live in an area of high dust or dander.
What size unit do I need?
There’s no easy answer for this one. A lot of factors will go into what size heating and cooling unit you’ll need. There are many factors that influence the size needed including the type of home, square footage, its walls, insulation, attic space, and more can go into determining what size unit is required. A system that is too large could result in a home that’s too humid, causing problems with moisture and mold. A system that is too small will run constantly, running up your energy bill. Only a qualified heating and cooling technician can determine what size unit is best for your home.
If I replace my outdoor unit, do I need to also replace my indoor unit?
In most cases, the answer is yes. There are a variety of reasons why you should replace both the outdoor and indoor units simultaneously. For starters, air conditioner and heat pump outdoor units are manufactured to work with a matched indoor unit.
Also, if you bought your indoor and outdoor units at the same time, your indoor unit will probably be approaching the end of its useful life at about the same time as the outdoor unit. By not replacing the indoor unit too, all you’re doing is delaying the inevitable and likely paying higher energy bills at the same time.
By purchasing indoor and outdoor units simultaneously, you’ll get a warranty covering the whole system, meaning that you won’t have to cover the full cost of any covered parts to your unit during the warranty period.
How often should I have my unit serviced?
To ward off any unnecessary surprises, it is best to have your unit serviced twice a year. Once in the spring and once in the fall.
How often do I need to service my boiler?
Once per year. Always prior to the cold season. It needs to be flushed and calibrated before the cold snap to run efficiently.
How do I find out if my unit is under warranty?
As soon as you get your new unit you need to register the unit with the manufacturer to receive the warranty. Check the label on the outer surface of your equipment to determine its manufacture date. If it’s less than five years old, there’s a good chance that your equipment is covered by a warranty. Give us a call and we can tell you about your active warranty.
What’s the best way to extend the life of my unit?
Heating and cooling units are a big investment, so it’s understandable that you’d want them to last as long as possible. Reducing usage is always helpful, so turn the thermostat up or down, as needed, to reduce use when you’re not at home. Changing air filters will prevent clogs. Regular tune ups by a HVAC professional will help prevent unexpected issues.
What Are the Signs of HVAC Problems?
You can tell your HVAC system needs repairs or replacement when you observe one or more of the following signs:
• Bad smells: The most common foul smells you might notice in your HVAC system include mold or mildew, burning, and decomposing. The problem could range from a dead animal to burning components.
• Poor air quality: If your air isn’t at the right temperature or isn’t circulating through the home, your system could suffer from a variety of issues.
• Weird noises: Unusual noises include banging, clanging, humming, rattling, buzzing, or clicking could be an indicator of a breakdown of internal components
• Power issues: If a device doesn’t turn on, doesn’t turn off, or turns on and off too quickly, it’s likely a power issue.
How Can I Lower My Energy Bills?
To help lower your energy bills, use the following best practices.
• Upgrade your furnace, air conditioner, and water heater to more energy-efficient models.
• Install a programmable thermostat.
• Use ceiling fans to cool your home or open windows to create a breeze.
