"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

"I called and spoke with Keith.  I told him the size of the home and approximately how many air ducts I had.  I let him know that the heating system was also apart of a central a/c system.  Keith was able to quote me a price of $500.00.  However I was able to get the 5% discount  so it came to $475.00.  He scheduled the appointment for January 30th at 10:30 A.M.  The hvac tech Brett showed up rite on time.  He was very pleasant and easy to talk to.  Brett got rite to work and started setting up for cleaning the ducts.  He worked alone and had a lot of equipment to carry in.  I had one vent that was hard to access but that was no problem for Brett.  He was able to clean it from below.  I asked Brett a few questions about the process and he was happy to explain them.  I believe Brett was finished in about five to six hours.  I am very happy with the service.

"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!"

"Patrick called Friday night and showed up at 7:15 AM on a Saturday morning (OMG) to repair a central A/C system that was icing up inside. I'm still waiting to hear from the other 2 companies that were listed in my area. I know they will call Monday which would mean myself and my disabled wife would spend a very uncomfortable weekend and probably longer because most HVAC companies don't work weekends and it usually takes at least a day to schedule an appointment. Not fun when the humidity is 65% and the temp is close to 80. Patrick did a great job, A/C is running like new. Will hire him again and recommend him in a heart beat. Prices are very reasonable. Hire him!"

Customers say: True professional

"Gary and Tina went well beyond my expectations. From a detailed explanation of the job upfront including pricing and finding a break in the duct work after they began the job. They visited 3 times (about 3 hrs r/t each visit) waiting for a hvac company to repair the duct work so they could perform the work previously detailed. Very professional, meticulous in their work and the house was as clean when they left as when they arrived. I will without hesitation call on them to perform their service in the future."

Heating and Air Conditioning FAQs, answered by experts

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.
