"We got an estimate from Jeff in early August (August 10) to install a ductless mini-split system in our MBR and family room.  Pretty basic job, Jeff said they have a whole crew that does only these kinds of job.  So you would expect them to be able to easily schedule and do this kind of job, right? Wrong.

Jeff's estimate was the most expensive of the 4 we got, but we were inclined to go with him because of the stellar Angie's List reviews.  We also liked him because he offered a 5 year labor warranty which he said JRB offers on everything ("We do that on all systems," he said - I wrote in my notes.)

His initial estimate was for $6,520 for two mini splits by Lennox.  We didn't really care which brand we got (we ended up with a Carrier) but we wanted a system that could heat the house even when it's really cold out.  Some of these systems are rated down to only 15 degrees F, but they're not good much lower.  When I told Jeff this he said he could research other systems, and I told him about a Fujistu system rated to -15 degrees.  He said he spoke with his distributor and he could install that system for the original quoted price.  (I was surprised because the other HVAC companies said the advanced systems were more expensive, but I figured Jeff's quote was originally high, so he probably built in some wiggle room.)

We scheduled the job 2 weeks out, for Sept 21 I believe.  Jeff's office sent me a contract to sign and return with a 50% deposit.



That's when the problems started. The contract included not a 5 year labor warranty, but 1 or 2 years.  I called and said Jeff told me it's always 5 and the woman in the office said that's not right.  Jeff called back and said we'll do 5 but that was special for you. (Again, that's not what he told me when he was trying to win my business - see above.)  So they sent a new version of the contract.  At some point I also gave them my CC number for the deposit, but they never charged it. 

I checked the parts numbers on the contract and they were not for the Fujitsu systems rated to -15 degrees. They were for a cheaper system.  So I emailed back and said there's a mistake again, please fix the part numbers.  I didn't hear back for several days.  I sent follow up emails and called.

Then, on Sept 17 - two business days before the work was supposed to start - Jeff sent me this email: "I'm emailing you to inform you that regretfully are retracting our estimate and involvement in your current project due to unforeseen circumstances. I thank you again for the opportunity. Have a great day."

That was the entire email.  No explanation.  No "Sorry, we messed up the price, it's actually going to be a bit more," (which we would have understood as I said).

I emailed Jeff back to say I was disappointed and would have understood if he needed to push the date or something, but to have no explanation or even a phone call leaves us in a tough spot.  No response.



We ended up getting the job done for cheaper ($6,300) by Shafer HVAC.  They did a great job, and you can find my review of them.

"They were very responsive and reached out immediately to schedule an appointment that worked for my schedule. Arrived on time and cleaned, serviced, changed filters and showed me how to maintain our system during the year. I will call them again when we need HVAC service or repair."

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"A great company, from the estimate to the install they were on time, informative and very professional. I really think I could not have found a better group of professionals to replace my current heat pump and air handler. Kudos to this company, I highly recommend you give them a shot at your HVAC needs. If their service is as punctual and professional as they have been for the install, I'm not sure you could find a better fit. Thank you Air Systems Mechanical and please say thank you to your team of guys for me who installed my system, they were outstanding! I found my go too for all my HVAC needs."

"We were so happy to have Sullivan Super Service (Plumbing, Heating, Cooling) come today to repair our central air conditioning unit and to service our HVAC system. Sullivan's technician, Bob Anderson, was polite, professional and experienced. We greatly appreciated his knowledge and counsel. Our AC has been out for a few days in a current hot spell, and Sullivan was the only company that contacted us. They proved the old saying that in winning, half of the battle is just in showing up and being there. We were not Sullivan customers before, but we are now! Sullivan's service was SUPER!"

"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

"Had a great experience with North Pittsburugh Heating. After getting screwed around by our home warranty company for almost 5 weeks (Choice home warranty btw, never use this scam of an agency), I contacted Tim independently to see how quick he could come out and get us a new condenser unit. Tim came out that very day to look at it and got our AC fixed within a week's time at a very good price. The tech's he sent to our house to do the job were also very courteous and helpful, amazing company! A major breath of fresh air after the nightmare we were dealing with previously. We'll definitely be using them in the future for our HVAC needs."

"Excellent service. Professional and quick! 100% would recommend. I live in a 100-year-old home whose ducts had never been cleaned. They managed to get it done quickly and the air feels so much better now. They even cleaned a birds nest from my bathroom extractor! Will be hiring them if I ever need carpet or duct cleaning done in the future."

Heating and Air Conditioning FAQs, answered by experts

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.
