Thermostats and Humidifiers: Find Your Comfort Zone
When it comes to an ideal climate, most humans prefer temperatures between 18C and 24C and relative humidity levels of 30% to 60%. Staying within this narrow window in areas like London, Ontario, is challenging.
Thankfully, Comfort Zones Services offers expert installation and maintenance for humidifiers and thermostats, helping you achieve the perfect indoor environment.
A properly functioning thermostat ensures your heating system runs efficiently, while a humidifier adds moisture to the air, reducing dryness and improving overall comfort.

Read our heating FAQs to find answers to all of your heating questions.
How often should I change my heater’s filters?
Most furnace filters need to be changed every one to three months.
However, be sure to check the filter manufacturer’s recommended replacement frequency when you get a new filter, as it can vary depending on factors like the filter’s thickness and efficiency (this is expressed as MERV, or minimum efficiency reporting value).
Not changing your furnace filter can cause your unit to work harder than it needs to, potentially necessitating a visit from heating contractors for furnace repair.
When should I contact you for heating repair services?
A damaged heating system doesn’t just lead to poor performance, it can also be a potential health hazard if not fixed.
As soon as you notice one of these issues, contact Comfort Zone Services to have your furnace, boiler, or heat pump checked out by our heating contractors:
- Banging, rattling, or squeaking noises coming from the unit
- Water pooling in the area
- Poor indoor air quality
- Burnt smells or acrid odors
- Rising energy bills
- Not getting the home warm enough
- Cold spots in the house
- Frequent cycling on and off
- The smell of gas (call your gas utility and then call us, as this is an emergency situation)
How often should I have my heater serviced?
You should have your heating system professionally serviced at least once a year, ideally in the fall before the cold weather sets in. Regular maintenance keeps your system running efficiently and can prevent unexpected, costly breakdowns in the winter.
How do I know if it’s time to replace my heating system?
If your heating system is over 15 years old, requires frequent repairs, or is no longer heating your home efficiently, it may be time to consider a replacement.
Upgrading to a new, energy-efficient heater can save you money on energy bills and make your home more comfortable.
Can I install a thermostat myself?
Though it’s possible to install a thermostat yourself, professional installation is recommended.
A heating contractor will ensure the thermostat is properly wired and calibrated to work efficiently with your system, providing accurate temperature control and energy savings.
What should I do if my heater stops working in the middle of winter?
If your heater stops working, check your thermostat settings and, if needed, replace the thermostat battery. Next, check your circuit breaker, fuse box, and filters.
If the heater is still broken, contact Comfort Zone Services for an emergency repair. Our Ontario heating contractors are available 24/7 and will get your system back on track!
