"AC Dave is a skilled and trustworthy HVAC company that does quality work at a competitive price. I had an aging four ton system that was on its last leg. My funds were tight at the time, so they suggested installing more efficient ducting to extend the system’s life. That was three years ago, which allowed me to save for the inevitable expense of replacement. And when that time came, I was given a comprehensive estimate and the installation went smoothly. They also did a follow up to tweak the system for maximum reliability. AC Dave is a small company, so you may not get next-day service, but they will work with you and stand by their work. In today’s less and less neighborly world, that is a real asset."

"My interaction with Air-Tech went very smoothy. Alex Fish, the customer representative was very professional and easy to work with. He provided a clear and detailed proposal , with options, before leaving the site on his first visit. Alex stayed in communication throughout the project. As a result of this experience I plan to have Air-Tech take over the maintenance on my main HVAC system."

"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."

Heating and Air Conditioning questions, answered by experts

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.
