"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."

"From the moment we inquired about services to job completion, we had a great experience working with Air Quality Concepts for our HVAC air duct and dryer vent cleaning. The owner Charles was incredibly prompt with communication and took the time to answer all our questions about the cleaning process prior to scheduling. We were so impressed by how personable, hard-working, thorough, and efficient our technicians Austin and Michael were when they cleaned our two HVAC systems. They were very attentive to the issues we have been having with our indoor air quality as we navigate mold remediation and health concerns. The company’s customer care was genuine and so appreciated, and the cost of services was very reasonable. We already feel more comfortable in our home knowing we are breathing cleaner air! I highly recommend Air Quality Concepts if you are looking to improve the air quality of your home!"

"On site within 2 hours of us calling. Very fast, professional, and affordable. The large HVAC company in our area was a 4 day wait, $125 just for diagnostics, and we have had repeated issues since they installed the units 2 years ago. Cardinal Mechanical was the opposite experience in every way."

Heating and Air Conditioning questions, answered by experts

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
