Air quality in the Fresno area can be negatively impacted by oak, birch and weed pollen, and by airborne allergens originating in the Central Valley’s agricultural areas. With our almost year-round warm weather and bright sunshine, though, indoor dust and dander levels can still be extreme when irritant levels outside are minimal. Happily, you don’t have to let fall allergies in Fresno get you down.

If you’re planning on adding on to your home, one of the first things you should investigate is how to heat and cool the new space. It might make a difference in how you design it or lay out its wiring and other mechanical systems. An HVAC contractor can advise you whether you can extend your current system, upgrade to a new one, or choose an independent HVAC system.
It’s important that you provide reliable and affordable heating and cooling for your San Joaquin Valley home, no matter the season. For you and other homeowners looking for savings, an effective way to accomplish this is to install ductless mini splits. These systems, often used for add-ons and extra rooms, don’t use ductwork to circulate conditioned air in your home, which means you won’t lose the significant amounts of air (and energy) that ducts typically lose through leaks and conduction.
Many homes use one thermostat to regulate temperatures for the entire house, despite the fact that different parts of the house have different climate-control needs. For families that want greater control over the heating and cooling levels in their home, however, a zoning system makes a great option. Rather than struggling to maintain one temperature for the whole house, zoning divides the home into more than one section, each with its own separate temperature control. Each zone might be a single room or multiple rooms.
Duct leakage can account for as much as 20 percent of the energy consumed by an average residence. It’s a major source of high utility costs for Fresno homeowners. California’s Home Energy Rating System (HERS) requires duct certification after a new central air conditioner or furnace is installed. The requirement has been extended to apply to change-out of individual components, as well, such as an air-handler, coil, or installation of more than 40 feet of ductwork. After the installation, an inspection must be carried out by a professional HVAC contractor using industry-standard equipment and practices. If leakage greater than 15 percent of system airflow is determined, duct sealing is required.
When was the last time you cleaned your clothes dryer’s vent? Like most people, you probably clean the lint screen regularly, but beyond the lint screen your dryer has a vent hose that carries hot air, humidity and more lint to the outside. Over time, that vent hose can become clogged with lint.
Sealing air leaks in your home is one of the most effective ways to improve the efficiency of your heating and cooling system, but only if you do it right. Poor sealing techniques won’t seal your home and will cost you money. Take the time to use the proper materials and technique to seal your home. Your HVAC system will thank you with lower monthly bills.
Before you install that new A/C, verify with the installation team that the company’s representative has sized it properly for your home. Going by your existing air conditioner can be misleading, and chances are the system you’re using is already too large. This is because most homes are more energy efficient than they used to be, as a result of weatherization improvements, including better air sealing and insulation.
