Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for HVAC contractors that have earned the prestigious Diamond Certified award. For All Weather Heating & Air Conditioning Inc., the key to achieving and maintaining high levels of customer satisfaction is simple: take a comprehensive, detail-oriented approach to every job, regardless of its size. “We want to make sure every customer is happy, so we never compromise on the quality of our work,” says owner Gil Medrano Jr. “It makes us feel good to consistently produce such great results, and it lets our clients know we’re running a quality business that really cares about helping people.”

All Weather Heating & Air Conditioning has been providing services that improve indoor air quality for residential and commercial clients in Solano, Napa, Sonoma, and Contra Costa Counties since 2003. The company primarily focuses on installing humidifiers, ventilators and electronic air cleaners made by industry leader Bryant, but it’s also qualified to repair, install and maintain all types of HVAC systems.

Unlike less experienced HVAC contractors that give estimates over the phone without seeing the jobs in question, All Weather Heating & Air Conditioning provides a free in-home estimate for every installation and repair project. “It’s difficult to provide an accurate estimate without looking at the system because certain issues might be symptoms of other unseen problems,” explains Mr. Medrano. “It takes in-person diagnostics by a trained professional to solve most HVAC problems, and that’s exactly what we provide.”

Another distinguishing attribute of All Weather Heating & Air Conditioning is its commitment to solving its clients’ HVAC issues instead of trying to upsell them on new equipment. “Heating and air conditioning is all about air flow, and that’s where our expertise lies,” says Mr. Medrano. “Instead of just installing new furnaces, we take the time to diagnose ventilation and ductwork, which helps us get to the root of each problem rather than relying on selling unnecessary equipment.”

If you want a healthier home, indoor air quality is a great place to start. Most modern homes are airtight and sound-resistant, but homeowners pay a price for that efficiency in the form of stale, contaminated, recycled air. Luckily, good HVAC contractors can improve your home’s indoor air quality via filtration systems and high-quality equipment. “Many homes don’t ventilate well, and you should definitely be aware of that for your health’s sake,” says Gil Medrano Jr., owner of All Weather Heating & Air Conditioning Inc. in Vacaville. “Homes have a lot of chemicals in the form of paint and carpeting, but good ventilation and fresh air counteract that and provide a cleaner indoor environment.”

Mr. Medrano says the best air filtration systems capture airborne particulates like molecules, gasses, formaldehyde, chloroform, mold, mildew, algae and pollen. “MERV filters attack these molecules, oxygenate them and turn them into air that’s safe to breathe.” Other air sanitizing systems use ultraviolet lights to scrub and sanitize air as it passes through the filtration systems.

Getting cleaner air in your home
If you’re in the market for a new HVAC system, make sure the one you choose has features that are designed to improve indoor air quality. Then, hire a qualified contractor who can install the system to code so it operates correctly.

If your existing system still works well, there’s no need to replace it. “You can retrofit for better indoor air quality,” says Mr. Medrano. “The first step is to make sure your existing duct system is sealed. If your duct system leaks and draws in contaminated air, it’ll spread that air to your home.” Duct leaks in attics, crawlspaces, garages or between walls can bring in toxins, diseased air, mold, allergens and other particles you don’t want to breathe.

Once your ducts are sealed, it’s time to clean out the furnace and ducts and add good air filtration systems to the unit. “A good filtration system makes a lot of sense,” affirms Mr. Medrano. “Maintaining good indoor air quality will keep you and your family healthier.”

Q: How much does a new HVAC unit cost?

A: Yes, we charge $79 to diagnose any existing equipment that needs to be serviced or repaired.

We always confirm appointments the day before, and we’ll call when we’re on our way or if we’re running late. We want our customers to get the best possible service, so our technicians only take one call at a time, which means they don’t have to hurry through an appointment.
