"The only time they had available was in the evening so I had to pay double the amount or a regular service call. I agreed to that because the temperature in my house probably around 40°. They gave me a timeframe for service from 5 PM to 9 PM and a service person would call when on their way. I was thrilled that Brett called me at before 5pm. Brett was very professional and thorough. He walked me through what needed to be fixed and prices. Within less than 35,minutes he replaced my broken igniter and answered questions about my desire to replace an 18 year old furnace."

"Nic was very accommodating to schedule my appointment next day and fix my furnace before the freezing weekend comes tomorrow. I tried another place and they can't do it until next week. He did a great job to quickly figure out what was wrong and equally quick for the fix. The price is also extremely reasonable. Can't thank you enough!"

"Early to appt. Nest and clean. Very knowledgeable. We do need a new furnace. But no pressure. Detailed, understandable replacement quote."

"Couldn't repair old furnace without excessive cost. Came out later thesame day gave us options with exact cost and replaced the old furnace the next morning. They werefair polite and wor j ed around our achedule. Highly recommend and will use them again to replace our air conditioner down the road."

"We decided to replace an outdated AC unit and furnace with a brand new heat pump and furnace. After speaking with a Four Seasons sales rep, we knew they were the best choice to go with due to their thorough assessment, knowledge of products, availability of service and overall transparency. And perhaps most importantly, they were not pushy and respect our decisions on what system we felt was best for our home. As with any expenditure of this nature, there will be some ironing out of details and inevitable bumps to get everything completed, but the overall experience amounted to an energy-efficient HVAC system that was installed with care and expediency. Their service technicians are also friendly, thorough, knowledgeable, and available at a moment's notice. We are so glad that we went with Four Seasons."

"As always, Mr. Duct kept in touch before hand, showed up absolutely on time, worked efficiently, and charged a very fair modest rate. The technician also noticed one or two things that we were trying to deal with (other than the furnace) and offered solutions with the equipment on hand. Saved us another call to another place! I'll have then back to clean the a/c and do our ducts (as they've done in past)"

"Installation of a new furnace and air conditioner was done. We were so impressed with the professionalism and follow through of the CR Mechanical team. Rick contacted us promptly and advised us of our options and his recommendations for our project. We did some additional homework and decided to hire CR Mechanical. Craig arrived on schedule and installed the furnace and did some additional pipe work the first day. On the second day, the AC was installed on the new compressor was relocated to a new area that we had discussed. The job was completed as agreed with efficiency and neatness. I would recommend CR Mechanical with hesitation."

"Home Advisor connected me w/ AVI Alliance Systems to install my smart thermostat. Andrew contacted me immediately, and was easy to communicate with through text, as I was unable to get on a call. He was able to come by same day and installed my thermostat in less than an hour! He also told me about other things that needed to be changed/fixed in my furnace, and explained everything. I will definitely be using AVI Alliance Systems for all my HVAC needs going forward!"
