It's important to stay comfortable year-round, and with so many choices on the market today, weighing the options like brand, efficiency, and technology can make for a tough decision.

Over the last 10 years air conditioning technology has come a long way. Today, all major brands offer central air conditioning equipment that is much more efficient, quieter, and more comfortable than anything on the market before.

All major brands offer systems that have a wide range of optional add-ons and price levels. The real difference that you need to consider when choosing a new AC system is installation and local support.

Why trust Jansen with your new cooling system?

We’ve built our family-owned business on referrals from satisfied clients, and are proud to uphold a commitment to superior installation and service.

Our technicians will size your system properly. A poorly sized AC system is the number one reason for dissatisfaction with an air conditioning system. If the unit is too big, you’re spending money on equipment you don’t need, and your system will be too loud, and will not control humidity properly. And if it’s too small, you won’t be comfortable on those hottest days of summer.

We prioritize the proper sizing and insulation of the ductwork your new air conditioning system utilizes. Jansen will be around, you can count on us with your seasonal maintenance and repair.

Jansen Heating, Air Conditioning & Electrical stocks air conditioning equipment from Armstrong Air. If needed we can often complete your installation the next day. Our installation teams are clean, fast and efficient.
