What Our Clients Say About Chill Heating & Cooling
faq
We answer them below.
Aim for once or twice a year. Routine maintenance will keep your system in optimal condition. It also ensures techs find problems early before they escalate. Get in touch with our HVAC company to book your service today.
There are several things you can do to make your system more efficient:
- Change your filters regularly
- Schedule maintenance of HVAC services
- Seal air leaks
- Install a smart thermostat
Yes! We offer heating and cooling services for urgent situations. Call us if your system stops working. We’ll do our best to fix the problem quickly (especially in times of extreme heat or cold).
Our HVAC maintenance services include a full system check:
- Filter inspection
- Cleaning
- Diagnostics
- Thermostat evaluation
- Refrigerant leak testing
Our goal is to catch issues early on before they progress.
Possibly. It depends on the individual situation. Most new systems have a manufacturer’s warranty for five to ten years. Some brands offer extended coverage if you use an authorized contractor (like us).
Call us! Several things could be the cause. It may be a problem with the condenser. Or it could be a dirty air filter. We’ll diagnose and repair the issue.
That’s dependent on the service. A full system replacement will have a different price than maintenance or a simple repair. As a trusted HVAC company, we provide estimated cost ranges after a quick phone call. We also offer on-site estimates for more complicated services like replacements or installations.
