Excellent customer services, high quality work for a fair price and the company has ethics. Family owned & operated for 15 years, this is not a corporate company. Lots of HVAC companies in the area so do your research when choosing a company and support local.

Nelson Rivas was SO helpful and very friendly. Would recommend him to anyone having issues with their AC. Hopefully I don’t have any problems in the future, but if I do, he will be the first person I call! :-)

Why DIY Isn’t Worth the Risk
Attempting HVAC repairs on your own can create more problems than it solves. Risks include:
- Voiding manufacturer warranties
- Electrical hazards or gas leaks
- Additional damage to system components
- Higher long-term repair costs
- Reduced system efficiency
- Short cycling – Ensuring your unit runs steadily without frequent restarts.
Routine maintenance is also key. Without regular tune-ups, dirty coils, clogged filters, and aging components can push your HVAC system beyond its limits. Cold Factor’s team has the tools and expertise to manage these challenges safely and effectively.
