HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter.

In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house.

Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.
The SEER (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER rating, the more efficiently a unit operates. The SEER rating of any given unit can range anywhere from 13 to 21.

“My A/C completely quit working recently so on recommendation from a friend I contacted Duggan’s for a service call and was surprised that calling on a Friday afternoon they were able to send someone out on Saturday to take a look. Peter showed up on time and quickly determined he would need to run a test but didn’t have what he needed on hand so he rescheduled for Monday. Peter showed up ahead of the appointment time(after confirming with me that it was okay), he wasted no time getting diagnostic testing underway and familiarizing himself with my Frankenstein system(which apparently has components from 3 different manufacturers). He maintained a professional and personable demeanor while quickly diagnosing the problem and explaining my options for repairs or replacement, and also patiently answered my questions(resulting in my finally having a minimal understanding of how A/C works), and all the while keeping a smile on his face. I would 100% recommend Duggan and Mr. Peter to anyone in need of any heater or A/C work!”

“Our tech who came out Initially Calvin was very informative, timely, polite, was great with our little dog. They gave us a Good feeling right from the get go. We have hired them to Replace our system and install an additional filtration system to help a bit with my allergies. The admin services have been very polite, and understanding. We Will keep them servicing our system after install.”

Kimberly Smith

“Reasonably priced work. Had our 1907 house power upgraded and rewired and porch fans installed. The electricians would not hesitate to stop and confer to make sure we were on the same page, eliminating costly mistakes from miscommunication. They were respectful of my home, cleaned up after themselves, and were very professional during the entire job. Would use them again and recommend them to others.”

“Spencer was undoubtedly the best informed and professional HVAC technician I have had show up for a service call. I am a serious technology nerd and he took the time to explain what and why he was doing what he was doing, as well as answer my potential upgrades to my system questions. This company without a doubt is my go to for all my needs going forward.”

Mike Baldwin

“Randell and the crew did a very thorough neat and clean job. The old system pan in the attic leaked at one time because of not having proper support. They installed new 2x4 bracing to support the new unit and pan. The job was outstanding and very professional in every manner.”
