Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.

Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.
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.

“McCarthy's is my go-to HVAC company. Before my appointment, I received a call to let me know that our technician was running ahead of schedule and they asked if it was okay to send him over. After I agreed, I got a text message with my technician's photo so I knew exactly who I was meeting. Cornell, our tech, was friendly and answered all of my questions. He provided me a review of what he did, and recommended services. I scheduled my next maintenance service on the spot. Highly recommend!”

Lindsey Jackson

“Our furnace went out when it was -12° on a Sunday. We called the company that put in our furnace two years ago and they told us they wouldn’t be able to get out to us for at least 24 hours. McCarthy came within a few hours. The technician was polite, knowledgeable and informative. Even shared what to do if we had further issues. I am SUPER pleased with McCarthy’s prompt and effective service!”

Catherine Todero

“Update! We had to replace our furnace and went ahead and upgraded to central air also and again completely fabulous customer service experience from all involved!! I cannot say enough good things about this company. We have had hell trying to even get a technician to show up before I found out about them. Their customer service from the moment you come into contact with them is superior to any company I have worked with in any field. They are true to their word, efficient and organized, timely and thorough. Mackenzie was friendly and accommodating, she didn't even react when I shrieked because my baby almost bumped her head on the table 🤣. Ethan located the problem right away, explained what was going on and looked over everything to make sure that it was functioning properly before he left. He was respectful and compassionate towards our family and wonderful to work with. I've been in customer service for twenty years and cannot tell you one time I have ever been made to feel this valued as a customer, especially as a potential customer not a returning customer. They saved us from freezing our butts off tonight, restored my faith in the field, and 100% earned a returning customer. We even signed up for a maintenance plan!! 10 stars!”

Heather Blackmore

“Wow! I had an amazing experience getting service for our heater from beginning to end. I booked an appointment online and there were plenty of time options for the next day which worked with our schedule. Before the technician arrived, I received a phone call to make sure it was ok for them to come. When the technician was on the way, I received a personal back story on Cornell who would be our technician. It helped so he didn’t feel like a complete stranger. Once arrived, Cornell was very professional, he even offered to show us where the problem was. I will definitely be using McCarthys One Hour company in the future. Thanks for the great service guys!”

Maria Jacinto

“Abel did a great job doing a service on our furnace. Did a run down on everything he did and some things he suggested we possibly have done in the future with the age of our furnace. Was quick and professional. House temperature is already feeling a lot better.”
