"CAWIAMCA did an outstanding job installing 2 high efficiency ductless mini splits – 1 at each end of my house. The owners Ron and Jeremy worked with me patiently on the system sizing and selection process, rebates from my power company, income tax credits, etc. Everyone on the installation crew was polite, conscientious, and knowledgeable. They came back next day to complete the installation of the second system despite snow and freezing rain!!! This company is well equipped to do the job efficiently. CAWIAMCA's price was much lower than the other 2 contractors I got estimates from (who planned to use concrete blocks to support the outdoor condensers). CAWIAMCA used quality steel bases with tall legs to support the condensers and keep them higher up away from snow, leaves, mice, etc. Nice looking installation. I could not be happier with a company. :-) CAWIAMCA!!!"

"The technician showed up as scheduled. I thought I was hiring a "local" contractor but he said he had driven 2 hours to arrive to my job site. The work was done satisfactorily for what could be seen as inspecting all the duct work was not practical."

"Very knowledgeable owner-operator. Prompt and personable. He repaired our 30-year-old central ac unit and did not try to upsell us to a new one. He was very thorough in his inspection of our system. I will use him again when we decide to replace our ac."

"I had Ryan do an A/C job for me and did a fabulous job for me! It was much cheaper than these big-name companies. It was for a split a/c unit. Very knowledgeable. I was a bit apprehensive at first but he did fantastic work and I've recommended them to others!"

"Bill was amazing from the start. Within an hour of submitting an inquiry through home advisor he immediately contacted me. Not only did he have questions but also provided minor troubleshooting steps to ensure it wasn't anything small causing my forced air system from consistently power cycling. Highly recommended."

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"

"I scheduled cleaning of my heating air ducts and also my dryer vent. The team arrived when scheduled and provided excellent service. The estimate provided was accurate and the time-frame was adhered to. They gave me update photos to show any problem areas and before & after pictures. They were respectful of my property and left every area where they worked in my house spotless. I couldn't be more happy with my entire experience."

"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

Air Conditioning FAQs, answered by experts

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
