"Having had bad experiences in the past, I can be pretty wary of contractors, but I need not have worried with Riley! We were in a no-heat situation during cold weather and he was able to move things around and get to us within a few hours. During the diagnostic, he insisted I was present as he walked me through what he was testing and what the expected results would be. There was full transparency. Once the issue was diagnosed, Riley offered different options to solve the issue. There was no sales pressure, he wanted to find the right option for us. Given the age and condition of our system we opted for a new HVAC system and Riley presented us with different solutions, again with no pressure. The installation was scheduled quickly and I was amazed with the quality of the workmanship and service he offered. His pricing is very fair but in terms of value for money, his service, professionalism, and workmanship easily beats any of the ‘big names’."

Heating and Air Conditioning FAQs, answered by experts

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
