DIAMOND CERTIFIED EXPERT CONTRIBUTORS IN THE Solano County – Heating, Air Conditioning & Ventilation (HVAC) CATEGORY

Gil Medrano: All-Weather Man

By James Florence, Diamond Certified Resource Reporter

VACAVILLE — When Gil Medrano’s first job out of high school didn’t pan out, he didn’t realize it would free him up for a much bigger opportunity. “I had just quit my landscaping job because the business owner couldn’t pay us,” he remembers. “That very same day, I was telling my friend about what happened and he asked me if I was interested in working with him in the HVAC field. I took him up on the offer, and after doing it for a while, I decided I liked the trade and was going to stick with it.”

It was a long road to reach his desired professional destination, but Gil says it was the best route he could’ve taken. “I’ve always wanted to have my own business, and I considered going for it a couple of times early in my career. However, in hindsight, I can see that I wasn’t ready. Later, I went back to school and got my bachelor’s degree in electronic engineering, which advanced me in the field and equipped me with a lot of valuable knowledge.” In 2000, Gil obtained his contractor’s license and soon thereafter achieved his dream of business ownership.

Today, as owner of All Weather Heating & Air Conditioning Inc., Gil says that while most of his time is spent in the office, he still prefers working in the field. “These days, I spend more time working on the business than for the business, but when things get really busy, I get to go out and do hands-on work. I still enjoy diagnosing and repairing HVAC problems, but what I like most of all is meeting and interacting with our customers.”

A resident of Vacaville (where he lives with his wife and business partner, Caroline), Gil expresses his fond feeling toward his long-time locale. “I was born in Hayward but I moved to Vacaville when I was a boy, so I consider it my hometown,” he says. “We raised our five kids here, and now we have grandkids, so you might say we’ve established some pretty hardy roots.”

Outside of work, Gil spends the bulk of his free time engaged in outdoor activities. “Our kids and their families are all local, so we like doing family camping trips and going boating at Lake Berryessa and Lake Shasta,” he says. “I also do some off-road racing with my modified Volkswagen Beetle. In addition to racing locally, this will be the third year I’ve competed in the Baja 1000.”

In regard to his professional career, Gil says being a business owner is a 24/7 gig. “I think some people get the impression that running a business is easy, but it’s anything but. There’s really no time off, so you have to be willing to put in the time, even when you don’t want to. It takes a lot of dedication, a lot of hard work and a serious commitment.”

Not surprisingly, when asked the first thing he’d do if he could retire tomorrow, Gil says he’d take a vacation. “Even when I’m on vacation, I still have to deal with work in one way or another, so if I were to retire tomorrow, I’d take a long, relaxing trip with no phone calls. I have a good friend in North Carolina who I haven’t seen in a long time, so I might go hang out with him for a while.”

Ask Me Anything!

Q: What’s your favorite sports team?
A: The Oakland Raiders.

Q: What’s your favorite style of music?
A: Rock and roll.

Q: What’s the strangest food you’ve ever eaten?
A: Escargot. We were on a cruise and they brought some out, so I decided to try it. It was pretty good.

Q: How do you like your eggs?
A: Over easy.

Q: Do you have a favorite movie?
A: I’m a huge fan of the “Star Wars” movies.

    Final Steps Before Hiring Heating and Cooling Contractors in Solano County

    A new HVAC system, furnace or home air conditioner is a big investment that should keep you comfortable for years to come. So before deciding on the best heating and cooling contractor in Alameda County for you, consider the following questions.

    A new HVAC system, furnace or home air conditioner is a big investment that should keep you comfortable for years to come. So before deciding on the best heating and cooling contractor in Alameda County for you, consider the following questions.

    • Can a local heating and cooling contractor in Alameda County meet your needs in terms of products, scheduling, installation and service?
    • Are the Alameda County HVAC company representatives knowledgeable on the furnaces and air conditioners they install? Can they tell you which brands and systems best meet your needs and why (i.e. energy efficient furnaces, high-efficiency air conditioners, new furnace installation, Trane HVAC systems, Carrier heaters and AC systems, etc.)
    • Is the HVAC installer sensitive to your budget? Can they offer various brands and heating and cooling systems to fit your needs? Most heating and cooling companies can give you bids for good, better and best options that give you more control over the price and efficiency of your new furnace and air conditioner.
    • Do the written warranties and guarantees offered by the local Alameda County HVAC contractors protect you and your new heating, cooling and ventilation system?

    Get More from Your New HVAC System Installation

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Most homeowners want the best value from their new HVAC system. But sacrificing quality to save money on a new heating and cooling system may defeat the long-term value you can get from a high-quality, efficient HVAC system installed by experienced and skilled heating and air conditioning professionals.

    To help encourage good HVAC contractors in Solano County to bid on your job, remember:…

    Most homeowners want the best value from their new HVAC system. But sacrificing quality to save money on a new heating and cooling system may defeat the long-term value you can get from a high-quality, efficient HVAC system installed by experienced and skilled heating and air conditioning professionals.

    To help encourage good HVAC contractors in Solano County to bid on your job, remember:

    • Look for good value, not just the lowest price. The first question most homeowners ask heating and cooling companies is how much their new furnace and air conditioner will cost, so it’s important to show them you understand the significance of quality products, skilled installation and long-term value.
    • Be upfront with heating and cooling companies if you’re interviewing other local HVAC contractors, but assure them that you’re accepting three fair bids, not dozens of lowball bids.
    • Shop among local heating and cooling companies in Solano County. Most HVAC installers like to work in the local area because it allows them to provide better service in a more timely manner. Shopping locally shows contractors you’re not looking for cheap HVAC installations, as some fly-by-night furnace and air conditioning services travel long distances to install discounted products that local contractors may not be able to compete with price-wise.
    • Take the long view when purchasing HVAC equipment. Buying a quality home heating and cooling system and having it installed by professional tradesmen can save you more money in the long run than buying a cheaper system or hiring discount HVAC installers.
    • Remember that the installation can be as important to the long-term reliability and functionality of your heating, cooling and ventilation system. Even the best systems require proper installation and maintenance to operate safely and at maximum efficiency.

    Request a Written Estimate from Your Solano County Heating and Cooling Specialist
    When you’ve found a Solano County heating and cooling company that meets all of your requirements, it’s time to sort out the details. Ask for a written estimate and contract that includes a confirmation of the brand and quality of your new HVAC system, any installation details, the price of the system and the labor for installation, and any applicable warranties and HVAC maintenance agreements. You should also get in writing a timeline that details the job start date, major milestones and the expected final installation date.

    You may also write in any additional requests or items you and the heating and cooling company representative verbally have agreed upon. Once you’re happy with the contract and understand all the terms of the agreement, you can sign with confidence.

    Once your HVAC system is installed, your heating and cooling professional should supply you with a written invoice. This invoice generally will list:

    • The name, physical address and license number of the heating and cooling contractor.
    • A list of all HVAC work performed.
    • An itemized list of the new furnace, air conditioner and ventilation system installed and any replacement parts needed.
    • The total heating and cooling unit installation cost, including an itemized amount due for labor.
    • Any applicable warrantees or guarantees.

    Once you’ve reviewed the invoice, it’s smart to compare the work that was actually done to the written document. Ask your cooling and heating contractor to show you the new system installation or HVAC repairs that were done. Check the products and work against the line-item invoice. This is also a good time to have the furnace contractor explain the HVAC unit to you in detail and show you the best steps to take in running and maintaining your new system. If you have questions about the work that was done or any items that seem to be missing or in conflict with your written contract or invoice, this is the time to ask your contractor.

Not all HVAC companies in Solano County offer warranties on their work and products. But if the company you’ve chosen does, they should give you a written warranty that includes:
