"Was having problems with my HVAC / heat pump. I didn't want to call the emergency number on a Sunday, but I saw I could schedule service online. I picked a date and time and received e-mail and text confirmation. Tech arrived on time and found multiple issues. It was a 17-year system, which they have worked on in the past. They have always been on time and updated me on their arrival time. We went over the options to keep the system running (repairs and parts), but ultimately decided it would be better to replace it with a new and more efficient unit. Keri, in the office, provided a few quotes for systems with varying options and efficiencies. I selected a variable-stage compressor unit, and I'm looking forward to the installation soon. I will post again after the install."

"Previously I had used Rod Poppe for our HVAC needs, however, when he retired he sold his business to Watkins.  When our air conditioning unit stopped running on Friday evening, I gave Watkins a call.  Since it was fairly late, their answering machine gave an option of leaving an emergency breakdown message or a regular message (which I chose due to the late hour).  On Saturday morning I gave them another call about 8:00 AM and left an emergency message since it was going to be a hot, muggy day and I needed the unit fixed ASAP.  I received a call back from Michael House, the on-call tech very quickly and by 9:30 he was at our house.  After doing a thorough analysis, he found a blown capacitor and low Freon level, but otherwise the 24+ year old unit was in good shape.  Michael was VERY professional, courteous, and thorough.  I would HIGHLY recommend Watkins for any HVAC work."

"Very good service at a fair price. Service Manager Nick gave no pressure options for my situation. I elected for a new install which was performed within two days. Nick was very knowledgeable and responsive to my questions and concerns. Joe and Kaleb did an amazingly good job integrating the new furnace. Thrown together old systems now look like one streamlined unit. It doesn't just "work," it was put in with some craftmanship (HVAC art). Will definitely continue to use this company."

"Mr. DeSoto did an outstanding job replacing two thru the wall air conditioning units at my home. He found two units that were available and had them installed within 24 hours. He is very customer oriented, well organized, prompt and value oriented. I would recommend him for any heating/cooling work you my need."

"Scheduling was a breeze, and  they even came out on a Saturday to do the work.   Bob (the owner) and Tyler showed up on time on the scheduled day.  They first explained the entire process and answered all of our questions.   Bob  even made a couple recommendations regarding the heating system in our home.  They updated us through the entire process, which took about 4 hours.   They moved all of the furniture back after the work was complete and cleaned up any messes.   I felt the price was competitive for the quality of work.  I would highly recommend this company for duct cleaning.

Heating and Air Conditioning FAQs, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

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.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.
