Is It Time for a Heating Replacement?
The answer isn’t always so clear. While your heater may be working, replacing it may be more practical in terms of long-term convenience and affordability. Definitely consider replacing the unit if you notice the following signs:
- Increasingly loud and unusual noises.
- Uneven temperatures around your home.
- The system is over 15 years old.
- Its efficiency continues to decrease.
- It runs constantly or frequently turns on and off.
- The cost of repairs is too high.
What Schaumburg Neighbors Say
Very good service. Technician did a good job, answered our questions regarding replacement of the furnace and thermostat, and was polite.
On the Mark installed a new furnace and AC unit today. Everyone I’ve dealt with during the process has been very courteous and paid attention to details, i.e., explaining my systems, clearly answering my questions, leaving things very clean, doing good, neat work, and double-checking everything before leaving. I would highly recommend them for maintenance or replacement.
Proposal was complete and explained everything to be done. Very pleased with price. Mark’s understanding of our needs and budget restrictions (retired) was heartwarming. Installation completed in 3½ hours, including cleanup! Would highly recommend for your heating and cooling needs.
