"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."

"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."

"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."

"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

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.
