"It went better than I could have imagined. All the other calls I made required a repair technician appointment and a separate salesperson appointment. Vitaliy the HVAC Doctor was extremely knowledgeable -- able to repair our old A/C enough to get us through until the new A/C was installed AND get us set up with a new one. We got a great new 2-stage A/C at a terrific price. Vitaliy really knows HVAC, and did a super job. Also, he has an incredible work ethic. He fit us in on short notice on a Saturday, and took his time answering all our questions. Once we were satisfied with the solution, he fixed everything by headlamp in the dark. He made sure we never felt pressured or rushed. We absolutely have a new favorite HVAC company."

"Great service, and helpful suggestions to keep my HVAC system cleaner.  The guys showed up on time and took care when working throughout the house.  I'll be using this company again in two years for our next cleaning.

"They worked around our schedule to come out for an est. and provide space heaters to keep us warm. The techs were fast and provided great quality. The sales person was honest with us in determining what options would be best for our size house. Great place for HVAC."

"After reading all of the horror stories people tell about HVAC companies, I feel a little out of place writing a raving positive review about the company I do business with. From the call to schedule a service to the salesperson helping us decide which stove best fits our needs to the technicians who install or service our equipment, every contact with Comfort by Design is like living in a commercial where everything goes right. The company always lives by its quotes, the technicians always go beyond the expected, and for the first time in my life I am not tempted to do the work myself to avoid the hassle and disappointment when the work isn't done well, quickly, or for the price I expected. If they keep this up, I won't know how to do anything for myself in a couple of years."

"Would 100% recommend this company to anyone that has HVAC needs. From start to finish everyone that I interacted with was helpful, knowledge, and kind! Spending a lot of money on a new furnace, air conditioner, and water heater is never fun, but Aquarius made it so easy. They listened to what I was looking for and make recommendations that would serve my needs (and not just the most expensive option). They were very accommodating with my schedule and were able to install everything while I was out of the State. Everyone made it easy for me to trust getting everything installed when I was not around."

Heating and Air Conditioning questions, answered by experts

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

Assessing location for airflow, convenience, and minimal noise impact.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it.
