"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"Palmer Gas & Oil just did an entire replacement of the 20-year-old central HVAC + humidifier + thermostats two-zone system in my home with a new state-of-the-art total system and I could not be more pleased. From start to finish each employee was personable, extremely knowledgeable, very courteous, and the consummate professional. There is truth to the adage that you get what you pay for and I know I got the best. All Gold Stars!"

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Customer service and communication was outstanding. The quick response to resolving our problem (hot water heater replacement) was greatly appreciated. Not sure if the 5-star â valueâ rating is appropriate since we didnâ t pursue competitive pricing...we didnâ t bother because they were exceptional on all other fronts."

"They contacted us in a prompt timeframe, confirmed the appt, showed up and did the job all in one day for a reasonable fee. The new fan/ light for our bathroom looks great and they cleaned up after their work. They were pleasant and wore their masks the whole time. We will definitely call Bob Daniels Electric when we have another electrical project."

Heating and Air Conditioning FAQs, answered by experts

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
