"The experience was very positive from the provider selection decision through the actual installation. Joe was quick to understand my general heating and A/C situation and make recommendations appropriate for my expressed needs and preferences, consistent with best residential HVAC practices. Pricing was very competitive. The installers Mike and Randy were professional, courteous, and careful throughout their work, and completely cleaned up the installation site when they were done. They arrived on time. They were responsive and very informative in regard to all my questions, and provided guidance regarding system operation after installation. I look forward to Droegkamp Furnace being my new heating and A/C service provider."

"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"When our furnace went out the company we have been using for 12 years said they couldn't come out for 3 weeks. When I called Bob he returned my phone call the same day & proceeded to help us resolve the problem. We now have a new furnace & since it was older we decided to have them take care of the air conditioner at the same time. Mamayek Heating was very fair with their quotes & they don't try to sell you a monthly "maintenance fee" for service. Their company is definitely more family driven & you don't feel like just a number, the owner truly cares."

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

"ThermaTek Heating and Air - Jamey Jamrosz, HVAC Specialist/Owner gave me a quote over the phone. I agreed to have him come for any evaluation of my AC. He arrived within 3 hours of my call. After checking everything out, he explained my options and the cost of each. I decided to go with the repair option, which he proceeded to complete the same day. Jamey was fast and personable. I will follow up with him for my HVAC needs for my condo. I will recommend him to my condo neighbors."

"Marty listened to my needs, inspected the existing systems and provided a fair quote. I met the installation team as they took a close look at the project -- they knew their stuff. I wanted to hire Fast Air but my house is not a standard type of house and the brand of furnace I wanted didn't come in the right size for the house. Marty talked this through with me so I understood the situation. That helped me tremendously when I talked with other HVAC contractors. Fast Air is a professional outfit. They absolutely are at the top of my short list."

Heating and Air Conditioning FAQs, answered by experts

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.
