When can you start my project?

After your initial call, we’ll look at our schedule, confirm when your equipment will arrive and tell you our soonest available start date.

What type of HVAC system does my house need?

It depends on the size of your home, but we’ll measure the square feet to determine what type of system you need to properly heat and cool your space.

Can you recommend a specific HVAC brand?

Yes, we can recommend different brands based on your needs and budget.

Does my new equipment come with a warranty?

Yes, we always offer a one-year warranty on our labor. Manufacturers’ warranties can vary—some companies offer five-year warranties on things like compressors, but others offer up to 10 years.

How often should I maintain my HVAC system?

If you use your system every day, we recommend replacing the filter every three months. You should also have a professional maintain the system every six to 12 months, depending on how often you use it.
