"Extreme Heating and Air Conditioning installed an 18 SEER HVAC system with zone control for me. I am very pleased with the results and performance of the system - far better than the previous system WRT air flow balance. All personnel were very knowledgeable and professional and I highly recommend this company. Thanks to Tristan, Brett, Ryan, Joe, Paul and special thanks to Dave and Tyler for working through some parts failures. I am very pleased."

"I like everything about them. They are personable, the gentlemen who owns the company, Bob, is very polite and careful with anything around the windows they are washing. Anything they have to move to do their job, they make sure to put back. They take great care to clean up after themselves, and respect me and my property. To top everything off, the work they do is always great!

The rates they offer are very friendly and competitive."

Heating and Air Conditioning FAQs, answered by experts

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.
