A furnace or heat pump is a long-term investment, and the contractor you choose matters as much as the equipment. Whether you need a repair, a tune-up or a full replacement, use this checklist to compare heating contractors in San Diego County.
1. Verify the license
In California, HVAC work must be done by a contractor holding a C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license from the Contractors State License Board. Look up any contractor's license number at cslb.ca.gov to confirm it's active and to see the business name, classification and any complaints. Precision Air Inc's license is CSLB #996275.
2. Ask about insurance
Ask for proof of general liability insurance and workers' compensation coverage. If a worker is hurt in your home or something is damaged, the contractor's insurance, not yours, should cover it.
3. Ask about equipment and training
Find out which brands the contractor installs and whether their technicians are trained on that equipment. Manufacturer dealers usually have direct access to parts, product training and warranty support. Precision Air installs Carrier, Bryant and Mitsubishi systems and services all major brands.
4. Get a written quote
A good quote spells out the equipment model numbers, efficiency ratings, what's included (removal of old equipment, thermostat, ductwork changes, permits) and the payment terms. If you're comparing bids, make sure each one is sized for your home rather than simply matching the size of the old unit.
5. Confirm permits
Replacing a furnace, heat pump or air conditioner usually requires a city or county mechanical permit and an inspection. A reputable contractor pulls the permit and schedules the inspection. Skipping permits can cause problems with insurance claims and when you sell your home.
6. Read recent reviews
Look at recent Google reviews for patterns: did the crew show up when promised, explain options clearly and clean up afterward? How a company responds to a less-than-perfect review tells you a lot too.
7. Know their hours and how to reach them
Ask when the office is open and what happens if you call after hours. Precision Air's office is open Monday through Friday, 8 am to 5 pm. After hours, our answering service takes your message and our office follows up the next business day.
Safety first: If you smell gas or a carbon monoxide alarm sounds, leave the home right away and call 911 or SDG&E from outside.
