We Deliver Heating and Cooling Service in the West Covina Community

Can you think of the last time you had your home’s furnace and air conditioner serviced? If not, you probably aren’t alone, but you may be accidentally shortening the lifespan of your HVAC system and increasing the possibility of serious problems down the road.

Even the best furnaces and AC units aren’t immune from problems when they’re neglected. Like vehicles, computers, and other complex machinery, a little bit of regular maintenance now goes a long way towards preventing problems later on.

Not all HVAC service is created equal, however. Here at Klaus & Sons Heating & Air Conditioning of West Covina, we have a long history of experience inspecting, maintaining, and replacing units of all sizes and shapes in a wide variety of situations. Paired with our excellent training and customer support, our technicians have all the tools they need to spot issues before they turn into big problems. An investment in your home’s HVAC system is an investment in the comfort of your home, so be sure you’re working with the right team when the time comes to perform preventative maintenance.

Of course, years of ignored maintenance and service (or perhaps just a small amount of bad luck) might mean you find yourself in a situation where you need your HVAC system fixed immediately. Though that’s obviously not the best situation, our team of technicians is here to help quickly identify and solve the problem. Whether you find yourself with a broken furnace in the dead of winter or an AC unit on the verge of breakdown in the summer, don’t be afraid to give us a call at ! We’ll ask a few basic questions and quickly dispatch someone to help fix your problem.

Unfortunately, even the best furnaces and air conditioners will eventually need to be replaced. (Some will last longer than others.) When that happens, there’s no one better to get in touch with than Klaus & Sons Heating & Air Conditioning. There’s a reason so many people in West Covina use us! Our best-in-the-business warranties back up our wide range of ENERGY STAR certified products designed to meet all needs.
