"We noticed a foul smell coming from one of the vents in our HVAC system. We turned the system off and called AC Dave. Dave sent Justin and James to troubleshoot the problem. They quickly found a tear in one of our ducts--and the remains of a dead rodent. They cut open the duct, cleaned it and resealed it. We had heat again, about an hour after they arrived. Very fast and competent service."

"A nice guy turned up on time to check my aging HVAC system to see there are any problems needing attention. He checked everything and gave me a clean bill of health. Other HVAC contractors have always presented me with a list of vague problems with a recommendation that I renew the whole system at $20,000 plus. It was refreshing to find someone honest for a change."

"⭐️⭐️⭐️⭐️⭐️ Integrity truly lives up to their name. We had them replace our entire HVAC system and also install a split system in our guest house, and the experience was excellent from start to finish. The team was professional, knowledgeable, and very easy to work with. They showed up on time, explained the process clearly, and made sure everything was done right. Replacing a full HVAC system can feel like a big job, but they handled it smoothly and kept everything organized and clean throughout the process. The split system they installed in the guest house works perfectly and was a great solution for the space. What really stood out was their honesty, attention to detail, and the pride they take in their work. It’s refreshing to work with a company you can truly trust. I highly recommend Integrity to anyone needing HVAC work and will absolutely call them again for future needs."

Heating and Air Conditioning questions, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
