Frequently Asked Questions

How often should heating systems be serviced?

All heating systems should be serviced annually, ideally before the winter season. Regular maintenance helps prevent breakdowns, ensures efficiency, and can extend your system's life by years.
Common warning signs include:

• Unusual noises
• Uneven heating
• Higher than normal energy bills
• Strange odors
• Frequent cycling on and off
• Failure to reach the set temperature
Furnaces typically last 15-20 years, while boilers can last 20-30 years with proper maintenance. However, older systems become less efficient over time, so replacing a functional system might still be the most cost-effective option.
Boilers use heated water and pipes to warm your home through radiators or in-floor heating. Furnaces heat air and distribute it through ductwork using a blower motor. Boilers generally provide more even heat and better humidity, while furnaces can heat spaces quickly and work with central air conditioning.
Common causes include:

• Thermostat issues
• Pilot light problems
• Electrical issues
• Dirty filters
• Low fuel pressure
• Mechanical failures If your heat stops working, our emergency service is available 24/7.
Regular maintenance is crucial for efficiency. Also consider:

• Upgrading to a high-efficiency system
• Installing a programmable thermostat
• Checking insulation
• Sealing air leaks
• Changing filters regularly
In Chicago's climate, a high-efficiency system often pays for itself through reduced energy bills. Newer systems can be up to 95% efficient, compared to 60-70% for older models. We can help you calculate potential savings for your specific situation.
You can:

• Change or clean filters monthly
• Keep vents/radiators clear and clean
• Monitor thermostat function
• Listen for unusual noises
• Check for visible issues

However, leave technical maintenance and repairs to professionals to ensure safety and warranty compliance.
Consider replacement if:

• Your system is over 15 years old
• Repairs would cost more than 50% of replacement
• Your energy bills are consistently rising
• You're experiencing frequent breakdowns

Our technicians can provide an honest assessment based on your system's age, condition, and repair history.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
