"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

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.
