The Heating & Air Company


Our team is here to meet all your HVAC needs, whether you've moved into a new home or want to maintain the equipment you already have. Here's how we can help.

  • New equipment installations
  • Responsive HVAC repairs
  • Preventive maintenance
  • Replacements and upgrades
  • Ductless heat pumps
  • Light commercial heating and cooling
  • Indoor air quality products

Air Conditioning Repairs, Maintenance, and Installations

Start the cooling season with a spring tune-up that covers all the major parts, from the compressor to the coils. We stock a wide selection of long-lasting parts if you need to replace a faulty component, such as a valve, switch, capacitor, or fan bearing. You can call on us for all your heat pump or air conditioning repair and maintenance needs.

Home Heating Equipment Services

Whether you have a heat pump, furnace, or dual-fuel system, we'll make sure that your heater runs strong all winter. We offer comprehensive tune-ups and responsive repairs. We can also upgrade your heating system. If your current system is over 15 years old, a replacement could lower your heating bills by 15% or more.

Indoor Air Quality Services and Allergy Relief

From dust and excess humidity to smoke and chemical pollutants, many homes have issues with poor air quality. At Wintri, we install tailored indoor air quality products that remove common allergens, such as pet hair, dander, and pollen. Our experts can give you more information and recommendations that are specific to your home.

Ductless Heating and Cooling

Ductless Mini-Splits are a smart solution for rooms that don't have central air ducts or need extra heating and cooling to feel comfortable. They're great for bedrooms, sunrooms, workshops, and additions. Customers also use them in offices and commercial buildings since occupants have the freedom to adjust the temperature and airflow in each room.

Light Commercial HVAC Services

Partner with our commercial HVAC contractors to experience optimal performance from your heating and cooling equipment. Punctual repairs minimize business interruptions, and preventive maintenance visits control operating costs while keeping your employees and customers happy.

Additional Services

Wintri also offers several other services in addition to those discussed above. Our experts are available for thorough duct cleanings that can help to improve the air quality inside your home. Furthermore, we install water heaters and tankless water heaters, and we provide electrical services like installing surge protectors and GFCI outlets.

Jay came out this morning, and I was his first customer of the day. He was incredibly kind, professional, and took the time to explain everything to me instead of just coming in and doing the repair. He changed out my filters, explained what happened with my AC, and even gave me a little much-needed lecture on maintenance and what I can do to keep everything running better. 😂 He was very upfront that he can get my system fixed and running today, but also explained why, in the long run, it would probably be in my best interest to start considering a new unit rather than just trying to sell me something on the spot. As a mom with three kids at home, having the AC go out in this heat is a BIG deal, so I really appreciated him getting out here first thing and making sure we would have air again today. Very knowledgeable, honest, patient, and easy to talk to. I really appreciate someone who explains the problem, gives you your options, and doesn't pressure you. Definitely recommend Jay!

Would recommend Wintri's HVAC maintenace team to anyone. They've been professional with excellent communication the entire time working with them. Jay recently performed semi-annual maintenace for the whole system and gave a comprehensive and insightful report with his recoomendations. 10/10 experience.

Wintri was the first and only call we needed to make for our AC repair needs! They came out first thing in the morning the very next day (which was a Saturday morning), and Supervisor Jacob and Kevin did an absolutely 100% perfect Job repairing and servicing our central air-conditioning unit. And they also provided us with a great quote for the installation of a new unit! 10 out of 10 in every way! - Ryan, Diane, and Nam

I had a refrigerant leak on my condenser coil. Wintri was fast to send a tech out (Jacob) and who was able to find the leak quickly and recommend we replace our 13yr old condenser with a new one. Jacob and Andy had the new condenser installed the same week and my house has never been as cool! Jacob & Andy were both very respectful. Pressure leaked everything before finishing and overall did a great job. Happy I chose Wintri to take on this job.

We had a great experience with this company. Keith came out to take a look at our aC unit, which was low on freak. He was incredibly kind and professional and took the time to clearly explain what was going on and what needed to be done. He worked quickly and efficiently, and before we knew it, our AC was up and running. It's such a relief to have it fixed so fast, especially in the warm weather. Highly recommend Wintri.

I highly recommend Wintri. The office was courteous, professional and immediately schedule a service visit. Keith was very knowledgeable, kind, and seems to truly care the consumer. You can just tell that he genuinely enjoys working with people and helping people...1 John 4:19. I appreciate their quick, careful, and caring service and the price is very fair.
