First off, Thank You and Congratulations on the purchase of your new heating and/or air conditioning system from Control Tech! Welcome to our family! We look forward to working with you!

In an effort to make your installation go as smooth as possible, here are some guidelines and helpful tips that can help you prepare for our install team!

  • Who is Home? Upon our arrival, we will confirm the work we are there to perform and will request authorization, in writing, to proceed. We ask that a homeowner, or customer who is purchasing the new system, is available upon our arrival (typically between 8:00-8:30am). In the event that you are not able to meet us at your home; whoever is occupying the home must be over the age of 18, or we will not proceed into the home.
  • Pets. Pets are perfectly ok to have around, most of our team are animal lovers! However, our technicians will be in and out of the home, or fenced in yard, at various times throughout the day. If you are worried your pet will escape, please have them in an area that they won’t be able to escape. Our technicians are very conscious about making sure pets don’t escape, but we always expect the unexpected. If your pet is not good with outsiders being in the home, we ask that you please put them in an area where they won’t be frightened and our team won’t be put at risk.
  • Clearances. As the technicians will go right to work upon arrival, it is crucial that they have a clear path too and from the indoor/outdoor units. For the indoor unit, please make sure that there is nothing blocking the furnace or setting on the furnace. Imagine having a 4ft bubble around the furnace and ductwork where the technicians will be working. Please make sure there is a clear path from the entry to the home, to the furnace; whether it be in the basement or upstairs. Most furnaces (boxed) are around 2ft wide and 3ft long. If the furnace is in an attic where the entrance is in a closet; please make sure clothes are removed as sometimes insulation will fall when we are getting in and out of the attic. At the outdoor unit, please make sure bushes are cut back a minimum of 2ft from the unit. Please make sure there is a clear path to and from the outdoor unit.
  • Driveway. During our installation process; we may ask to park in the driveway as it provides the closest access to the new heating/air conditioning system. If someone in the home has a vehicle in the garage that will need to be moved at some point during the day, the technician will typically ask to swap you places (no he/she will not park in your garage) so that you can come and go freely throughout the day.


  • Who Will Be Coming to My Home? There will typically be two technicians to install your new heating and/or air conditioning system. Our install technicians will generally arrive between 8:00-8:30am. They will go over the installation with you and confirm the services they are there to provide. They will ask you to help them locate the equipment they will be replacing.
  • How Do They Protect My Home? Our technicians will wear shoe covers, and until further notice due to COVID-19 guidelines, they will be wearing a face covering and will not be shaking hands or performing any kind of physical contact in order to hopefully reduce the chance of spreading COVID-19. They will lay down canvas drop cloths from the entry of the home, to the location of the furnace or work area.
  • How Long Does the Installation Take? Most equipment can take all day to install. We define “all day” 8-10 hours. Sometimes, we will be required to come back a second day to finish the work. While that second day is not always consecutive, we will try and schedule it as close to your installation date a possible. Typically if we are installing a new furnace that will reconnect to your existing flue/exhaust venting; this work can take approximately 4-8 hours depending on the setup.
  • How Long Without Heating or Air Conditioning? Depending on the time of year, you may be without heating or air conditioning for several hours. Once the heating or air conditioning is turned back on; you can expect a recovery period of approximately 1 degree per hour. For example, if in summer; you will be without air conditioning for several hours. When they turn the system on for the first time (at the end of the day) the thermostat may say 80 degrees, but you normally have it set for 72 degrees. Please know that it could take approximately 8+ hours to recover and get back to set temperature. Your new system will be doing all it can on extremely hot days so please be patient. As far as heating goes; with natural gas or propane furnace, you may have a quicker recovery time than with an electric furnace/heat pump, so again, please be patient.
  • Do the Technicians Take Lunch? Typically, yes, our technicians break for lunch. Sometimes they pack their lunch and eat on site. Sometimes, they leave and grab a quick bite. Typically, lunch is no more than 30 to 60 minutes. If someone is home, the technicians will tell you they are breaking for lunch. If you are not going to be home, we ask that you please tell the technicians how you want them to lock up the home while they’re gone for their lunch break.
  • What’s that Smell? Most of the time, especially with a new natural gas or propane furnace, you will smell a slight odor when the system turns on for the first time. This is very normal. These units are made in a factory and sometimes have residual oil on the heating elements that will cause a slight odor. Also, when installing a high efficiency gas or propane furnace, we do have to use PVC glue and cleaner to install the PVC fittings for the venting. This will have a strong odor that will dissipate after several hours.
