"Peter and Mark were very professional. I needed to replace the HVAC dampers and the communication with Peter was excellent and we had all questions answered ahead of time so we didnt have any last minute surprises. They showed up on time and installed the dampers and the HVAC control panel. Very thorough and clean with their work. I've already recommended them to my neighbors."

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"He was timely, professional and responsive. He clearly knows the technical aspects of the trade and provided us with a lot of information about the equipment he would be installing and how it would work with our existing ductwork.  We did not care for his sales approach because he tried to sell us on things we did not ask for and did not need.  He tried to sell us on a humidifier for the system which we really don't need because we live right by the ocean where it is quite humid year round, even in the winter. Adding humidity to our house could cause problems with mildew or mold.   He also tried to sell us on replacing our hot water tank for a more efficient model even though ours is only 5 years old.  We got the feeling that he was trying to pack as much sales onto the heat loan program without really thinking about the customer's specific situation, and that put off me and my husband from wanting to work with him.  At the end of his sales presentation he decided on the spot he would give us an unspecified discount.  We did not like this high pressure sales tactic.  We had not received other quotes yet so we declined to decide on the spot.  He emailed us a couple days later offering a 10% discount if we decided by a certain date a couple days later.  We decided to wait beyond that date so we could get more bids.
Joe's quote was $2000 higher than a quote from another installer who has equally good reviews on Angies list.  Both quotes were to install the same equipment, however the second installer included the cost of converting two unused ducts into returns and installing a pass though in a ceiling to help balance our system.  I shared this information with Joe, and he responded by saying he would beat their price by $100.  It goes to show that it pays to shop around. 
As Airco's good reviews on Angies list attest and my interactions with him, I am sure they would do quality work, but my husband and I were totally put off by his sales and pricing approach and did not want to work with the company as a result.

"I've used this company for a few years, beginning with an issue I had where I needed some emergency assistance with an a/c system leaking water into the house. They fixed the issue and it cost far less than I thought it would. I've also used them for a couple heating repairs, annual furnace cleaning and a/c maintenance. I am about to hire them again since the a/c system is dying and it will need replacement since it's more than 20 years old. I would highly recommend Unique Indoor Comfort to anyone in need of a good HVAC/Heating company."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"I am months late getting this review in; sorry for the delay! We were out of state when we got word (from a neighbor) that our heat pump was making quite a loud noise. Got on Angieâ s List and found Dodge. Called and left a message (it was, of course, over New Yearâ s weekend!). Keith called me and said he would have it checked out first thing in am on )an 2, which did happen. (I did also call another local company who never responded:( Keith was able to repair our heat pump, which (he mentioned this as well) is on borrowed time! We really appreciated his dedication and immediate response/attention to our problem; it was quite a relief that this was taken care of... TU Keith :)"

Heating and Air Conditioning FAQs, answered by experts

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable
