"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"It went well. Not sure how many years it's been but Dave continues to solve the many riddles around our boiler (house circa 1930). This time was not so bad but I simply don't call anyone else PERIOD. Waste of time when you can work with a savant. Just as an FYI - he's pretty much done my entire basement from PEX to a water filtration system."

"You want an honest HVAC company? Look no further. Dave and his crew were the only people who would come and fix our boiler wiring- everyone else was either too busy or refused to deal with a smart thermostat. They came when they said they would, did the work, and charged exactly what I was quoted beforehand. So, when our 20 year old boiler stopped lighting, I called again. And again, he showed up when he said he would, explained what was going on, and charged an exceptionally reasonable price to fix it."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

"I feel confident in Ryan and Sons’ knowledge and expertise in caring for my 250-year-old house. They have serviced my water softener, hot water heat, furnace, as well as performed other services that come up in an old house. Their communication is excellent, sending emails and calling so I know when to expect them. With a service plan on my water system, I get a discount on other services , too - you can’t beat that! Highly recommend!"

"The technician was very professional and was able to answer many of my questions about the condition of my HVAC system that I inherited and its probable lifetime. I sensed that he was being honest and straightforward. Rather than accept his extensive list of possible replacement parts, I opted to have him install the one that he believed to be the most urgent- the capacitor. So far the unit seems to be functioning well."

Heating and Air Conditioning questions, answered by experts

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Though it may seem redundant, you can absolutely have a central AC unit and a window AC in your home. In fact, if you place a window AC unit near your central air, it can help move the cooler air throughout your home. But doubling up on your AC methods can get pricey, so factor in cost accordingly.
