"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!!!"

"Y and M Air Duct cleaning provided an important service in a way that was transparent and professional. Our house is noticeably cleaner as a result of the service. They were punctual, polite and clean. They did not cut corners and showed me what they were doing and cleaning every step of the way. The world would be better if more contractors had Y and M's work ethic."

"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!"

"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."

Air Conditioning FAQs, answered by experts

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
