"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"I needed the water heater replaced at my house as soon as possible and Alex was super accommodating. I couldn't be more satisfied with his service. His professionalism and expertise were evident from start to finish. Not only did he provide a great price, but his work was also top-notch. He arrived on time, communicated clearly, and ensured everything was installed correctly and efficiently. I highly recommend Prime Cooling and Heating LLC for any HVAC needs. Excellent service!"

"I would give MORE stars if I could. Service was excellent. Greg arrived at the appointment time, was clear about what he would do and how he would do it. He was very clean in his work. He removed all duct covers, then began the cleaning. I had some issues with the antibacterial disinfectant (allergies) he would be using. He advised I could research it and let him know. He even allowed me to smell the disinfectant. We did use it and the smell was very mild and dissipated in about a half hour. After cleaning the duct work, he returned all the duct cover and cleaned up his work area. He worked by himself and had the job done in under 3 hours. And the price was fantastic, coming in at over $150.00 and $300.00 less than 2 other bids. If you're looking for duct cleaning for your HVAC system or dryer (he did that, too!), The Duct Pros are where you want to go! Thank you Duct Pros!"

Also took the time to keep the entire job site spotless and walk you through the whole process. Cares about doing the work right and is an all around professional. Will definitely go with Strive for all my HVAC needs in the future."

Heating and Air Conditioning FAQs, answered by experts

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.
