"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."

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"I hired Marco about 4 months ago. I had just bought a house and it was in good condition but needed updating. Marco has been amazing. He does good work, is reasonably priced and competes the work on time. I initially hired him to replace the tile in my first floor power room, replace the toilet and the vanity. Marco did an amazing job, he very detailed oriented and didn’t cut corners. I eventually hired him to do the same job for our second floor bathroom, replace the tile in our laundry room and will be asking him to do the same for my master bathroom. In addition, he painted, did trim moulding, etc. He also removed flooring (tile, vinyl wood and linoleum) and helped us prep for hardwood installation.

"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

Heating and Air Conditioning questions, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

If an air conditioner is younger than 10 years, it’s worth trying to repair it in most cases. Some basic maintenance or a cleaning might bring it back to working condition. However, many HVAC pros swear by the “5,000 rule.” If the estimated cost of your repair multiplied by the unit’s age is more than $5,000, it’s time to replace it.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

A new HVAC system can add 5% to 7% to your home’s value, especially if you upgrade the entire system, including ductwork and insulation. In total, these upgrades could bring around a 30% return on investment (ROI). Add a smart home thermostat, and your home’s value could increase because the heating and cooling systems are more modern, efficient, and convenient.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.
