"Before I called Maynor, I had 4 other companies give me an hvac replacement quote. Maynor was the 5th. I was very impressed with Mike who gave me the estimate. He exactly gave me the picture of what HVAC I was going to get and gave me choices and time to think about it. I decided to go with Maynor because of their reputation. NATE certified installers. I was right. Junior and Biri came to install my trane hvac with both heating and cooling. I also had zoning done. Very professional. Came on time at 7:30 and finished around 4 pm as I had zoning done the same day. Very impressed with the work done and the efficiency is to say the least. The next day, Jaime (supervisor) came to my house and reassured me that everything is working great. I appreciate the reassurance as it is a big investment. They are open 24/7 and they listen to your needs. Competitive quote and honestly lower than everyone else considering the quality of work. My heating was in the attic and the work was outstanding (I took before and after pictures and inspected everything they did). The zoning works perfect. If you are looking for quality, efficient and superb work, go for Maynor. You will never go wrong. I had researched, read all reviews and got estimates from 4 other big hvac installers. I was not convinced until I met Mike who was honest, detailed and organized. The only one who gave me the specific model number of the hvac I was getting and educated me regarding the different kinds of hvacs. Also, he did not push me to go with other brands like all the other 4 companies did. Maynor took care of me and I know they will take care of you too."

"Sam is excellent! He replaced two HVAC systems for me, took the time to talk through and price-out many different options, solved some problems along the way, and when an issue arose he stood by his service and made it right. Sam is a professional and I've already recommended to friends."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

Heating and Air Conditioning questions, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

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.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.
