"I used their website feature to request a tech for residential A/C repair for the following day. But I received a phone call from Cytech a couple of hours later asking if I wanted service earlier as they had a tech available at that time, which worked out even better for me. The service call and repair was completed in 45 minutes after tech arrived in a efficient and professional manner. Tech even went above and beyond the repair and fixed up a couple of minor issues without charging me anything additional. I'll will be calling them again in the future should I need HVAC services!"

"Great thermostat installation service. The technician was punctual, professional, and made the entire process easy to understand. The new thermostat works perfectly, and they took the time to ensure everything was properly configured before leaving. Excellent customer service and quality work. Highly recommend!"

Customers say: Super punctual

"Cost was just about what I expected. But in the future, quotes should be labor + materials. The work completed in a reasonable amount of time considering the project and weather conditions. The work done was done in a professional manner. I would recommend them highly, and would hire them again on any major project for my home. This project was an unexpected project due to the damage caused by the last storms high winds. The project was installing Duraskirt repairing siding that was torn and painting the steps to my home. I have insurance but all the Insurance could do is replace and repair storm damage. But, I wanted to upgrade my home and the work done did just that. My recommendation is give Raul a call if you want quality work."

Heating and Air Conditioning FAQs, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

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.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.
