"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

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.
