FAQ
Common Questions About Commercial HVAC
How long does commercial hvac services take?
Most commercial hvac services jobs are completed in a single day. The exact timeline depends on the size of your home and whether any ductwork modifications are needed. We handle everything — equipment sizing, permit coordination, installation, and commissioning — so you are not juggling multiple contractors. Call (619) 792-8289 to schedule a free in-home estimate.
How do I know which system size is right for my home?
Correct sizing requires a Manual J load calculation — not just a rule-of-thumb based on square footage. An oversized system short-cycles and leaves your home humid. An undersized one runs constantly and never reaches setpoint. Karam performs a proper load assessment at the free estimate, factoring in insulation, window area, ceiling height, and local climate data.
Are there rebates available for new HVAC installation in San Diego?
Yes. San Diego Gas & Electric and the California Energy Commission both offer rebates for high-efficiency equipment including ENERGY STAR-rated heat pumps and variable-speed systems. Federal tax credits under the Inflation Reduction Act may also apply for qualifying heat pump installations. We help identify which incentives apply to your project during the estimate.
Is Everglade Heating and Air licensed and insured?
Yes. Everglade Heating and Air is fully licensed, bonded, and insured in California. Owner Karam Shaker holds NATE certification — the industry's highest field technician credential — as well as an EPA 608 license required for handling refrigerants. He personally oversees every job, which means you always know exactly who is in your home and who is accountable for the work.
Do you provide free HVAC estimates?
Yes. We give free, no-obligation estimates for all HVAC installations and major repairs. Call (619) 792-8289 or submit a request online and we will schedule a visit at your convenience. There is no pressure to book — we want you to have accurate information so you can make the right decision for your home and budget.
How fast can you respond to an emergency HVAC call?
We offer same-day service across all of San Diego County. For most neighborhoods, Karam can arrive within 30 to 60 minutes of your call. We keep the truck stocked with the most common parts so emergency repairs rarely require a return visit. Call (619) 792-8289 now — the sooner you call, the sooner your home is comfortable again.
What makes Everglade different from other HVAC companies?
The biggest difference is that Karam Shaker — the owner — does the work himself on every job. You are not getting a franchise technician or a subcontractor. That means consistent quality, honest recommendations, and someone with a real stake in the outcome. We are also NATE-certified and EPA 608 licensed, and we back every job with a parts-and-labor warranty.
