"I went with this company to replace my furnace and air-conditioner. My furnace went out on a Friday night, they came out to give me a bid on Monday and replaced both units on Tuesday. I chose them because their price was within $100-$200 of the big companies, but Precision is owner operated. The owner gave me the bid and was here to do the installation. I appreciate the owner doing the installation as he has a lot of experience and will be the one I call if something goes wrong. They only took 6 hours to do both installations - it was quick, clean, easy and well done. Highly recommend."

"We have an older home with older ductwork. We had Spencer and Brayton out and they cleaned and sealed our ductwork. They did a great job. Professional, great communication, attention to detail. They reduced our air leakage by 86%. We noticed an immediate difference in improved airflow, our cold spots are no longer cold spots. Thanks!"

Air Conditioning FAQs, answered by experts

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.
