"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."

"Ducts were cleaned as we contracted for. When they finished the HVAC ducts they said they would do the dryer vent as a complimentary service. I told them I had recently cleaned it and they would probably not get much lint out of the vent. I was amazed at all they got out and it was at no additional charge."

"Affordable Heating and Air is by far one of the most responsive and reasonably priced HVAC contractors that I have dealt with. They were able to work me into their schedule less than 24 hours after I submitted my request and less than 4 hours after talking with someone from the company. They employees were very kind and quickly completed the job."

"From beginning to end of this process, Thermo Direct was outstanding! I had 2 other estimates done. My first choice, based on Nextdoor reviews, Arctic Air showed up smoking a cigarette. Continued to smoke while looking at my HVAC. Very unprofessional. Never received my estimate. Said their email was having issues at the time. It's been a month now and I've never heard back. 2nd company had a great salesman and prices but, they were referred to me from Angi's list and when I checked their reviews, they were terrrible. So, I called Thermo Direct. Eddie Blanchard was very informative and thorough. He made sure to follow up via calls and texts and was always available if I had any questions. In fact, I almost didn't use Thermo Direct as I'd found reviews for ThermoAC and they were awful reviews. When I told Eddie this, he pointed out their 4.7 star rating. I soon realized that I had clicked on the wrong name. But, I still didn't have 3 comparison quotes. Roto Rooter cancelled the first ap"

"Parker and Company Heating and Air completed a discounted tune up at my property and I was highly impressed with the quality of service that was provided. They were prompt, friendly, and spent a reasonable amount of time inspecting my HVAC unit and providing preventative maintenance. I feel comfortable in the future that I will continue to reach out to Parker and Company whenever I need HVAC services. Their pricing was also very reasonable!"

Heating and Air Conditioning FAQs, answered by experts

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.
